Addressing Emissions From Coal Use in Power Generation

November 2008

Coal is a cheap and abundant resource, and carbon dioxide (CO2) from coal use is responsible for about 40 percent of global greenhouse gas (GHG) emissions from fossil fuel use. The United States and China are by far the largest emitters of CO2 from coal consumption, accounting for nearly 60 percent of global CO2 emissions from coal, with India a distant third. The United States currently relies on coal for roughly half of its electricity generation resulting in roughly one third of total U.S. emissions. China generates 80 percent of its electricity from coal, and in recent years, emissions from coal use have grown five times faster in China than in the United States. With enough coal reserves to meet current consumption levels for centuries, the United States and the rest of the world face the challenge of reconciling the realities of coal use with the dangers posed by climate change.

Carbon capture and storage (CCS) is a means to meet this challenge. If widely deployed, CCS could allow the world both to continue to exploit its cheap and abundant supply of coal and to adequately address the threat of climate change. CCS works by separating CO2 from other gases in the exhaust stream at power plants and industrial facilities, compressing the CO2 to pressures suitable for pipeline transport, and injecting the CO2 into deep geologic formations where it can be safely and indefinitely stored.

Although components of the CCS suite of technologies have been used in a variety of situations, the entire suite has not been deployed at a commercial scale at any coal-fueled power plant to date. Deployment has not proceeded for a number of reasons, primarily the high costs of installing and operating CCS technologies and the absence of government policies that place a financial cost on GHG emissions. In addition, uncertainties remain concerning actual cost and performance of CCS technologies at commercial scale. Finally, CCS deployment requires an appropriate regulatory system for CO2 storage, including long-term liability.

This brief describes the potential role of government in facilitating widespread and more rapid deployment of CCS through a number of means including: providing financial incentives for initial CCS projects through the use of bonus allowances under a cap-and-trade program, or a fund generated by charges on electricity or fossil-fuel based sources of electricity; setting GHG emission performance standards for coal generators or electricity providers; and establishing the required regulatory and liability frameworks for CO2 storage.

Technology Policies to Address Climate Change

November 2008

This brief presents public policy tools available to provide support for research, development, demonstration, and deployment (RDD&D) of technologies that reduce greenhouse gas emissions. An emissions price induced by a cap-and-trade program can provide an incentive to “pull” new technology into the marketplace, while public funding for technology can provide a “push” with the two approaches more powerful in tandem than either alone. Economic theory provides the rationale for public expenditure on RDD&D, which can compensate for several market failures that would otherwise generate sub-optimal investments from the private sector. The appropriate policy tool depends on the stage of development for a particular technology and the scale of a project. Direct public expenditures, channeled through organizations such as the Department of Energy or the National Science Foundation, have a long history of funding earlier stages of research and development, and make up the bulk of current technology dollars. Some technologies to address climate change, such as next-generation nuclear power and carbon capture and storage, require a larger investment for early projects than private industry is likely to make, and could benefit from public funding of demonstration projects. The federal government can also provide inducements for private industry to invest in RDD&D with mechanisms such as investment tax credits. Indirect policies that can support technology deployment include standards that require a minimum performance or a market share requirement, and programs that identify and certify top efficiency performers in the marketplace. Funding sources for technology programs include appropriations from general revenues and dedicated revenues, perhaps from climate- or energy-related sources such as allowance auctions or dedicated energy taxes. Regardless of the source, funding must flow through and to multiple institutions that manage, select, and perform the actual RDD&D options. Each institutional option has strengths and weaknesses.

U.S. Election and Prospects for a New Climate Agreement

Read the full article

By Elliot Diringer
October 2008

This article was first published by the Heinrich Böll Stiftung Transatlantic Climate Policy Group.

After years of stalemate in the international climate negotiations, the inauguration of a new U.S. president presents an opportunity for a genuine breakthrough.  Both John McCain and Barack Obama support mandatory limits on U.S. greenhouse gas emissions, and both favor renewed international engagement.  But unrealistic expectations about how quickly the United States will move – and how far – could severely damage prospects for any sort of agreement next year in Copenhagen.

An effective post-2012 climate agreement is impossible without the United States, the world’s largest economy and largest historic emitter.  Europe was able to persuade other developed countries to push ahead with initial commitments under the Kyoto Protocol despite the U.S. withdrawal.  But there appears very little appetite among those countries to take on new, stronger commitments without the United States, and even less prospect of commitments by the major developing countries.

Fortunately, there is at long last real momentum for stronger efforts to reduce U.S. emissions.  While skeptics remain, the political establishment has largely accepted the scientific consensus that human-induced warming is underway and must be addressed.  Many states are taking mandatory steps to reduce emissions; 24 states have entered into regional initiatives to establish cap-and-trade systems.  Many corporate leaders are calling for mandatory federal action, and Congress is seriously debating the establishment of an economy-wide cap-and-trade system more than twice the size of Europe’s Emissions Trading Scheme.

Statement: Dingell-Boucher Draft Legislation Released

Statement of Eileen Claussen
President, Pew Center on Global Climate Change

October 7, 2008

I commend Chairmen Dingell and Boucher for their leadership in producing draft legislation that advances the climate change debate and demonstrates the commitment needed to pass national climate policy in the next Congress. I am strongly encouraged that, even in the midst of challenging economic times, Chairmen Dingell and Boucher remain focused on producing a thoughtful piece of legislation that would reduce U.S. greenhouse gas (GHG) emissions.

I'm especially encouraged by the Chairmen's approach to reducing GHGs through an economy-wide cap-and-trade system. Cap and trade is the most economically efficient way to meet our most urgent environmental imperative. The discussion draft also looks to control costs with sensible mechanisms and to encourage rapid deployment of efficient and low-carbon technologies.

As with any draft, there is room for improvement and refinement, and here I look forward to seeing the debate progress, especially in discussions about the near-term emissions target, trade measures, and appropriate regulatory authorities. I recommend that the final bill include tighter caps requiring that GHG emissions be reduced to 1990 levels by 2020. Also, trade measures should only be considered as a last resort, and not be implemented before 2020 to allow other efforts to protect energy-intensive industries enough time to succeed. Finally, I am concerned about some proposed options regarding the pre-emption of existing state and EPA authority under the Clean Air Act.

That said, I salute the Chairmen for their dedication to tackling this difficult challenge and am anxious to get started on the work ahead.

Climate Policy and Natural Gas: A Bridge to a Lower-GHG Future

Speech by Eileen Claussen, President, Pew Center on Global Climate Change

American Gas Association Executive Conference

October 6, 2008

I am delighted to be here and to add my welcome to Washington.  

Of course, I am here to talk about global warming, but I can't stay away from politics, and I think it is interesting that, even in the middle of our economic troubles, the presidential and vice-presidential candidates are talking about this issue too.  Governor Palin, for one, has publicly acknowledged that her state is suffering from the effects of higher temperatures.  Polar bears are disappearing, coastal erosion is a problem, her poll numbers are melting … it’s a real mess.  She also said rising sea level is uprooting coastal communities so they have to move inland.  And you know what that means: it’s getting harder to see Russia.  So there goes all that foreign policy experience.

But Governor Palin still isn’t sure of her position on the causes of climate change.  When asked if man had anything to do with it, she said it was a sexist question and women should get some credit too.

The Obama campaign, for its part, already has shown it has the capacity to keep a lid on dangerous emissions. Joe Biden was on live TV for 90 minutes last week and he kept the verbose answers to a minimum and did not "emit" a single gaffe.  That’s quite an achievement.

There was one awkward moment – when the moderator asked what he thought about CAP and TRADE, Biden thought she was talking about Governor Palin's children.    

In all seriousness, Charlie Cook has given you a true insider’s perspective on the 2008 elections and how things are shaping up.  What I want to do today is talk about what all of this means for climate policy – or, more specifically, what we can expect to see in the next year or two as Washington finally comes to grips with climate and energy issues in a serious way.  

We all know that climate legislation has been making the rounds, and the Senate actually considered  a major cap-and-trade bill this summer.  But as I reflect on what is likely to happen in 2009 and 2010, I am reminded of the old Monty Python line … “And now for something completely different.”   

I predict that we will see real legislation, a real debate, and real action on the climate issue in the next Congress .  And what happens on this issue will obviously have important implications for the natural gas industry – which I will discuss in some detail later in my remarks.

But first I want to offer some perspective on the state of play in Washington right now – and where we stand today in the effort to forge a response to one of the most urgent global problems of our time.  

The reality of course, is that at the moment, all of Washington has been caught up in trying to rescue the U.S. economy, and so the question becomes – again – will the immediate crisis trump the need for climate policy?  Many seem to think so, but I have a different view.   

Certainly the new Administration and the new Congress will have a very full plate, but I do not believe that climate policy will fall off the agenda – and there are 4 reasons why I say that.  First, there are very high global expectations (unrealistic expectations, actually ) for what the next administration will do on the climate issue.  Foreign countries are anxious and frustrated with the lack of action by the U.S.; they are hoping for quick and dramatic changes from the new Administration.  If the next President wants to get off on the right foot with the global community, something that will serve us well on a variety of  critically important foreign policy issues, it is imperative that we craft and pass reasonable national policy, and that we engage constructively with the rest of the world on a global framework for action.   

Second, there is momentum and pressure from corporate America and from the states.  In the midst of this economic meltdown, the Western Climate Initiative unveiled their design recommendations for their regional cap-and-trade program – the most aggressive design to date in the U.S. - and RGGI, the consortium of northeastern states, held their first auction on Thursday Sept. 25– ringing the opening bell on Wall Street no less!  In total - 24 states are currently involved in regional cap and trade programs.  And corporate America is ready for the certainty that a well-designed national policy will afford them.  

Third, the Supreme Court decision in Massachusetts v. EPA paves the way for a more traditional “command and control” regulatory approach to addressing greenhouse gases.  Continued inaction is not an option.  If federal legislation doesn’t move, an approach based on existing Clean Air Act authorities is more likely – and yet less cost-effective – than a greenhouse gas cap-and-trade program.  And as this summer’s DC Circuit decision vacating the CAIR rule illustrates, it’s not clear that EPA can choose a more flexible and cost-effective approach such as emissions trading – or determine an allocation under a cap – in the absence of specific authorizing legislation.   So traditional standards (at least under some parts of the Clean Air Act) are the more likely outcome, a scary thought for many in industry and in the Congress.

And finally, and most important of all, we cannot have a growing, competitive economy without both a comprehensive energy policy and a sound climate policy.    A good climate policy will drive private and public investment in new, cleaner technologies, create jobs, and help us to transform our dependence on foreign energy supplies. Conservation and efficiency will help stabilize the climate, and make us more energy secure.  Moving forward with alternative, renewable technologies will decrease our carbon footprint and harness our innovation agenda.  Doing whatever we can to make use of existing cleaner, greener technologies, whether expanding our use of nuclear energy, or mounting a crash effort to demonstrate carbon capture and sequestration, or expanding our supplies of natural gas, have to be a part of our energy and climate policy.  Because without a major effort in all of these areas, I do not believe our economy will rebound, I do not see us being globally competitive, and I see us spending far more of our tax dollars in responding to the serious effects of a changing climate than we would spend preventing them.   

And, happily, since this economic crisis erupted – both Senator Obama and Senator McCain have reaffirmed their commitment to addressing climate and energy policy, including working for passage of a greenhouse gas cap-and-trade bill.   

So – while I believe some will try to use the current economic situation to obfuscate and delay – I do not think they will succeed.   Certainly, it  will be a challenge getting people to pay attention to climate change. But the bottom line is we have to.  We don’t have any other choice.  And to the extent that we can make the connection between protecting the climate, decreasing our dependence on foreign energy supplies,  and advancing the economy, I believe we will be successful.  

Now back to the state of play.   I am sure that all of you followed what happened in the Senate this summer on the Lieberman-Warner bill.  Whether you agreed with the specifics of that measure or not – and believe me: we had our share of concerns about the bill, as I am sure many of you did … But the specifics aside, this was truly an historic moment: the first time ever that comprehensive climate legislation came to the Senate floor out of a committee.  

And how did the Senate greet this historic opportunity, this unique chance to engage in a civil and substantive debate about how best to get this nation on track toward reducing its contribution to climate change?  

The answer is they engaged in a knock-down, drag-out partisan fight over Senate procedures.  Because of an unrelated dispute over judicial nominations, opponents of the bill dispensed with Senate courtesy and forced the reading of the entire 492-page bill into the Senate record.  It took nine hours.  

Now, if you are going to take up nine hours of the public’s time reading aloud on the Senate floor, the least you could do would be to read from the classics, or Harry Potter, or perhaps Chicken Soup for the Soul of an Aggrieved Public.  The Climate Security Act of 2008 was, sad to say, not a page-turner.  And the wasted opportunity, and the wasted time that these shenanigans entailed, are even more galling when you consider that Congress wasted no time this summer passing bills recognizing National Corvette Day and the National Day of the American Cowboy.  

But still … but still there was the fact that bipartisan climate legislation had been voted out of committee and reached the full Senate.  And it was an important reminder of how far we have come on this issue in the last ten years.  

When we started the Pew Center in 1998, many people in the United States still viewed climate change as unimportant, unproven and undeserving of a lot of public debate.  Now, ten years later, Washington is moving ever-closer to developing a national plan for reducing U.S. greenhouse gas emissions, many U.S. states and cities have adopted innovative climate strategies of their own, and we have two major-party presidential candidates who both are committed to taking serious action on this issue.  For all their differences, John McCain and Barack Obama agree on the salient facts about climate change.  They agree that this is a real and an urgent problem, that it is caused in large part by human activity, and that the United States must focus on solutions.  And they even agree, albeit with some differences, on the broad outlines of a solution: a strong domestic cap-and-trade law coupled with U.S. support for a global climate change agreement.  Where there is a real difference is when you contrast the McCain and Obama positions to what’s happened in the last eight years.  

So we have come a long way indeed.  And one of the main reasons we’ve come this far, as I see it, is because of people like you.  All across this country, there is an ever-expanding contingent of business leaders who are saying they trust the science on this issue and it’s time to act.   

Today, the Pew Center’s Business Environmental Leadership Council includes 42 companies representing roughly $2.8 trillion in market capitalization and more than 3.8 million employees.  It is the largest U.S.-based association of companies committed to climate change policy and business solutions.  Members come from a range of sectors, including oil, high technology, diversified manufacturing, transportation, aluminum, electric and gas utilities, chemicals, healthcare, insurance, financial services -- and, of course, natural gas.  Our members include Exelon, PG&E and other natural gas industry leaders.

These companies share our belief that climate change is an urgent problem that will affect our economy and our communities in profound ways in the years and decades to come.  And they believe, and I quote: “The United States should significantly reduce its GHG emissions through economy-wide, mandatory approaches,” including a “flexible, market-based cap-and-trade program.”

Last year, many of these same companies took their advocacy on this issue to a new level when they joined with the Pew Center and others to form the U.S. Climate Action Partnership.   The USCAP group has issued a cap-and-trade proposal with specific targets and timetables—a real plan of action to slow, stop and reverse U.S. emissions. In addition to cap and trade, the group has embraced an array of other policies aimed at building a low-carbon energy economy.

So we have seen enormous progress, in large part because of business leadership on this issue.  But, of course, we still have an enormous amount of ground to cover.  And now people are looking ahead to what will happen – or, more precisely, what must happen – in 2009 and 2010. 

And so here’s my prediction: The Pew Center anticipates that the next President, whether it is John McCain or Barack Obama, will propose a framework for achieving substantial reductions in U.S. greenhouse gas emissions, including a cap-and-trade program, during the first half of 2009.  We expect Congress to begin debate on comprehensive climate legislation in the same timeframe, and we believe it is likely that a cap-and-trade bill will be signed by the President during the 111th Congress.  
As of January 20, 2009, the date of the next president’s inauguration, the question driving the U.S. debate on this issue will not be whether we need comprehensive, mandatory action, but how to do it right.  And the major challenge facing the next Administration and Congress as they seek to answer this question will be to resolve the cost and spending issues associated with comprehensive climate action.  

How can we minimize and contain the overall costs of a mandatory program?  How can we provide relief for those who will be most affected – including energy-intensive industries that will face higher fuel prices, regions of the country that rely on less climate-friendly sources of energy, and consumers who will face higher prices for electricity?  How can we reduce administrative costs and bureaucracy?  And, last but not least, how should we spend and invest the estimated trillions of dollars in future allowance value that could flow to the government, the private sector and consumers under a cap-and-trade regime?

Answering these questions will not be easy, which is why the next President and Congress should get to work right away.   And, of course, the questions I have asked are only the beginning.  Of great interest to all of you will be how our leaders here in Washington address specific questions having to do with natural gas.  And that’s where I want to focus in the remainder of my remarks.  

The Pew Center soon will be publishing a paper on the coverage of natural gas emissions under a cap-and-trade regime.  According to this paper, combustion-related GHG emissions from natural gas are 16 percent of total U.S. GHG emissions.  The largest source of emissions from the burning of gas is industry, accounting for 5.3 percent of total U.S. GHG emissions, followed by the power sector, at 4.4 percent.

Clearly, regulating and reducing GHG emissions related to the use of natural gas has to be part of any solution to climate change.  But the question, again, is how to do this effectively and fairly … how to do it right.   

This is a question that has spurred a very intense and very impassioned debate – well, as impassioned as you can get, I suppose, when throwing around terms like “points of regulation” and “allowance allocation provisions.”  

Seriously, the debate has been intense because these are important decisions with wide-ranging implications for your industry and for our economy as a whole.  And one of the biggest decisions that lawmakers will have to make has to do with the point-of-regulation issue.   The issue, as you know, is this: Should we regulate natural gas-related emissions on the upstream side – at the point where gas is produced and processed and distributed to consumers?  Or should it happen downstream – where gas is actually used?  

Well, to adapt the classic round, “Row Row Row Your Boat,” I say the chorus right now should be “thoughtfully down the stream.”  The Pew Center supports downstream regulation as the short-term answer to the point-of-regulation question.  And I say “thoughtfully down the stream” because we need to think carefully about how to do downstream regulation right.  More specifically, I agree with the AGA that it is impractical to include small-volume consumers of natural gas as part of any emissions cap.  Rather, we believe that any cap-and-trade measure that becomes law should cover downstream emissions from large users in the industrial and power sectors.

Over time, we believe local natural gas utilities should become responsible for meeting a cap on emissions related to the service they provide to residential and commercial customers.  This will make them “covered entities,” to use the legislative lingo.  (As an aside, I think it’s interesting that the only other statutes using the term “covered entities” are those governing indecent exposure.)

How many facilities would this kind of downstream approach cover?  Well, let’s do the math …

Our forthcoming paper estimates that fully 54 percent of the natural gas consumed for combustion in the United States is consumed at facilities producing more than 10,000 metric tons of greenhouse gases each year.  If we set that volume of emissions as the threshold for new regulations governing large users of natural gas, our paper says it would cover about 7,000 manufacturing facilities, plus 500 gas-only power plants and 750 or so compressor stations.  That adds up to about 8,250 facilities that would be regulated for their downstream CO2 emissions from natural gas consumption.

Accounting for co-ownership of these facilities and other factors, the paper comes up with a final estimate of 5,382 entities to be regulated under this approach.  Add the largest 150 LDCs, which account for 95 percent of gas throughput, and you get 5,532 covered entities – a number that could clearly be accommodated within a larger cap-and-trade program.  At the Pew Center, we believe the best choice is to include these large LDCs right now, but we recognize there are differing opinions.  The AGA has said that LDCs should not necessarily be included as covered entities now, and I hope that in the spirit of compromise we can agree that LDCs should at least be phased in.  Whether we phase them in or not, the largest LDCs are certainly an appropriate point to regulate the gas industry over time if we are looking at downstream emissions.

But at the same time that we are discussing “points of regulation” and all these other technicalities, we also need to consider something else – and that is how to better support natural gas as a bridge fuel to a more climate-friendly energy supply.

This is a real opportunity for your industry – this is not a “bridge to nowhere” that we are talking about.  Natural gas provides a bridge to the future.  To the extent that you can deliver gas at a reasonable cost, you can be part of the solution to climate change.

But here’s the problem: this industry cannot come close to fulfilling its role in protecting the climate without a strong policy push from Washington.  If natural gas is to play a role in helping us reduce greenhouse gas emissions, we need to keep it affordable, and we need policies to help make this happen – policies to help expand our natural gas infrastructure, policies to keep costs down, and policies to increase natural gas supply.

And we also need policies to help make natural gas even more efficient as a fuel source.  This industry is doing great things  to promote increased energy efficiency.  And America’s natural gas companies are funding programs that help their residential and commercial customers reduce their natural gas use by 9.5 trillion BTUs per year.  The resulting reduction in CO2 emissions: 500,000 metric tons every year.  

From home energy audits and cash rebates to low-interest financing for high-efficiency natural gas appliances, your industry offers consumers an array of tools to help them get a better handle on how much energy they use, and reduce it.  Today, according to AGA’s own data, the average American home uses one-third less natural gas than in 1980.  This has happened even as demand for energy has risen, and it can be explained in part because consumers are installing energy-saving windows and insulation, buying more efficient appliances, and taking other steps they might not have taken in the absence of incentives and active encouragement from America’s natural gas utilities.

Take PG&E, which I already mentioned is a member of the Pew Center’s Business Environmental Leadership Council.  PG&E offers its gas customers a rebate of up to $300 toward the purchase of an energy-efficient natural gas furnace, up to $400 toward the cost of sealing leaky ductwork, and up to $150 per 1,000 square feet for insulation.  That is real money, and a real incentive for PG&E’s gas customers to do their part to save energy and protect the climate.

This is important and commendable work.  But we can do more, with  tightened product and equipment efficiency standards, stronger building codes, and more.  We also need to make sure that natural gas utilities have the right economic incentives to promote efficiency.  The bottom line is this: Utility profits should not take a hit when customers use less natural gas.  The government needs to step up its support for innovative utility rate designs that encourage increased energy efficiency.

And this is why industry partnerships are so important.  The Pew Center has been proud to stand beside our business partners in the U.S. Climate Action Partnership and advocate for sensible solutions to climate change.  And we feel there is much more room for additional partnerships on this issue – between NGOs and business, and among business and NGOs and government.  With active industry involvement, I strongly believe that we can develop not just the right technological solutions but also the right policy solutions – solutions that make sense given the issues that all of you face in your businesses each day.

In just one month, the election will be over and a new President-elect and Congress will begin the work of preparing to take their seats at either end of Pennsylvania Avenue, just blocks away from where we sit today.  They will have a lot on their plates – a lot of people coming after them to do their bidding on issues from the economy and health care to energy and climate change.  And my challenge to you is this: as an industry, natural gas needs to do everything in its power to make absolutely certain that the climate issue receives the attention it deserves.  

We will not have another chance like this … and the longer we wait to act, the harder and more expensive this problem will be to solve.  Indeed, some say we have a window of just a few years.  We are going to need to use all of the persuasive power we have – all of the contacts, all of the political savvy – to make the case for workable solutions to the climate problem – solutions that combine all of the tools we have at our disposal to reduce greenhouse gas emissions.  Natural gas is one of those tools – and a crucial one.  We just have to help our leaders figure out how to use it right.  

Thank you very much.

Federal Court Activity

Over the past decade, individuals, NGOs, trade associations, communities and even whole nations are increasingly using the federal courts as a venue to address climate change. While some claimants bring suit to enforce or clarify existing laws and regulations, others seek relief from the detrimental effects of increased carbon dioxide emissions. Still others challenge the very legitimacy of climate change law and regulation. How the courts handle these cases can and will continue to fundamentally impact industry, government, law, policy, and the environment.

The following exemplifies the most relevant case law impacting climate change activities of the last decade. Taken together, they illustrate the main challenges plaintiffs have used to bring suit, the core legal defenses that opponents have presented, and the ways in which the federal judiciary is approaching climate change litigation

Click on the links below to view case summaries within each respective area of litigation.

Clean Air Act/Pre-emption Cases

In 2007, the Supreme Court ruled in Massachusetts v. EPA that Greenhouse Gases (GHGs) are air pollutants covered by the Clean Air Act. The Court made clear that the Environmental Protection Agency could regulate Greenhouse Gases under the Clean Air Act, if the Administrator made a determination that greenhouse gas emissions were a danger to human health. In 2009, EPA did just that, and found that greenhouse gases (along with six other air pollutants) threatened the health and welfare of present and future generations. Prior to these findings, parties brought legal challenges questioning whether the Clean Air Act applied to greenhouse gas emissions at all. More recently, challengers questioned whether actions taken by EPA to regulate emissions were outside of their legal authority. Still others have challenged whether federal action (via EPA and the Clean Air Act) preempts states from regulating greenhouse gas emissions. The following cases illustrate these arguments and the associated court holding.

Common Law Nuisance Claims

Perhaps the most difficult challenge confronting plaintiffs in climate change litigation is the problem of demonstrating that the emission of GHGs to the atmosphere by a particular activity or facility will give rise to specific impacts on a local area or population. Proving causation, a causal link between the defendants activities and the plaintiffs harm, seems to be a daunting challenge. In the last decade, parties have used a tort (a civil wrong) called nuisance (a legal inconvenience resulting in damage) to challenge defendant corporations whose activities result in large amounts of GHGs being released into the atmosphere, which allegedly lead to global warming events that result in damages. The following cases illustrate how plaintiffs have you used the federal common law nuisance and how the courts have responded.

National Environmental Policy Act Cases

The National Environmental Policy Act (NEPA) established a U.S. national policy promoting environmental improvementt. Of significance, NEPA set up procedural requirements for all federal government agencies to prepare Environmental Assessments (EAs) and Environmental Impact Statements (EISs) whenever environmental effects of a federal project cross a certain threshold. EAs and EISs contain statements of the environmental effects of proposed federal agency actions. The following cases illustrate challenges against government agencies who have allegedly failed to sufficiently analyze or disclose information about the implications of their projects and programs as they relate to climate change.

Clean Water Act Cases

Oceans readily absorb carbon dioxide (CO2) emissions from power plants and other human activities. In turn, the CO2 causes seawater to become more acidic, lowering its pH level. This process, known as ocean acidification, impairs the ability of marine animals to build the protective shells and skeletons they need to survive. Certain provisions of the Clean Water Act require EPA to protect waters from pollution, such as ocean acidification. In the following cases, challengers have alleged that the Environmental Protection Agency, in failing to recognize the impacts of ocean acidification on waters, have violated the Clean Water Act.

Renewable Fuels Standards Cases

EPA's 2012 Renewable fuels standards require gasoline producers and importers to displace a certain percentage of their total gasoline production with the purchase of cellulosic biofuels.The following case is a challenge brought against the EPA for its 2012 Renewable Fuels Standard (RFS) volume mandate. Specifically, it challenges the reasonableness of EPA's decision to require refiners to blend domestic fuel with cellulosic ethanol or pay a penalty.

Public Trust Doctrine Cases

The Public Trust Doctrine imposes a legal duty on the U.S. Government to hold vital natural resources in 'trust' for present and future generations, including protecting the trust asset from damage or loss. In the following cases, plaintiffs claimed that the atmosphere, including the air, is one of the crucial assets protected by the Public Trust Doctrine, and that defendant federal agencies have allowed, facilitated, and contributed to the waste of trust assets, including the atmosphere, by allowing it to become polluted with high levels of human-caused CO2.

Endangered Species Act

The Endangered Species Act (ESA) aims to protect species and the ecosystems upon which they depend. It is administered by the U.S. Fish and Wildlife Service and the Commerce Department's National Marine Fisheries Service (NMFS). Under the ESA, species may be listed as either endangered or threatened. "Endangered" means a species is in danger of extinction throughout all or a significant portion of its range. "Threatened" means a species is likely to become endangered within the foreseeable future.

The Obama Administration has repeatedly stated that the ESA is not an adequate or proper legal mechanism to regulate GHGs. However, the effects of climate change are far reaching. On March 1, 2013, the D.C. Circuit upheld the U.S. Fish and Wildlife Service's (FWS) decision to list polar bears as a threatened species under the ESA after the agency determined that climate change threatens the bear's habitat and range. In particular the polar bear's primary habitat, sea ice, is rapidly decreasing as a result of climate change.

National Environmental Policy Act Cases

Alec L. v. Jackson (United States District Court for the District of Columbia, May 31, 2012). 

Five children, along with the groups Kids vs. Global Warming and WildEarth Guardians, sued the heads of several federal agencies for failing to adequately address global warming. The plaintiffs proceeded on the theory that the atmosphere is a commonly shared public resource that defendants, as agency heads, have a duty to protect under the public trust doctrine. As relief, plaintiffs asked for an injunction directing the named federal agencies to “take all necessary actions to enable carbon dioxide emissions to peak by 2012 and decline by at least six percent per year beginning in 2013.” Defendants and intervenors argued in a motion to dismiss that plaintiffs failed to state a valid claim for relief. The district court agreed and dismissed the suit.  Relying on the recent Supreme Court decision PPL Montana, LLC v. Montana (2012), the court held that the public trust doctrine is a matter of state, not federal, law. It further held that even if the public trust doctrine were a federal common law claim, such a claim has been displaced in this case by the Clean Air Act (as was similarly held in the 2011 Supreme Court case American Electric Power Co. v. Connecticut).

Loorz v. Jackson (United States District Court for the District of Columbia, April 2, 2012). 

A federal district court in Washington D.C. allowed business groups to intervene in a lawsuit that seeks to require the federal government to establish a plan for an immediate cap on GHG emissions and start lowering these emissions by six percent a year beginning in 2013. Several advocacy groups, including Our Children’s Trust, filed the federal lawsuit in May 2011 along with similar actions in many states. The lawsuit alleges that the federal government has a duty under the public trust doctrine to reduce GHG emissions in the atmosphere. So far, no state challenges have been successful.

Association of Irradiated Residents, et al.  v. California Air Resources Board (Superior Court of California for the County of San Francisco, October 20, 2011)

Background:  On September 27, 2006, then Governor of California Arnold Schwarzenegger signed into law the Global Warming Solutions Act of 2006, or AB 32. The law seeks to fight climate change through comprehensive program reducing GHG emissions from all sources statewide. The act requires the California Air Resources Board (CARB) to develop regulations and market mechanisms that will cut the state’s GHG emissions to 1990 levels by 2020—a 25% reduction statewide.

On December 17, 2010 CARB selected a cap-and-trade program as the market mechanism to cut the state’s GHG emissions. CARB scheduled the program to take effect in 2012, placing a limit that would decrease by two percent each year through 2015. From 2015 through 2020, the proposed limit would decrease by three percent annually. AB 32’s rules would first apply to some of the major emitters—utilities and large industrial plants. In 2015, the rules would apply to fuel distributors as well, eventually totaling 360 businesses throughout California. The market would begin with a distribution of free allowances to businesses accounting for approximately 90 percent of the business’s overall emissions; however, for any additional emissions, the business must purchase the necessary allowances.

Case Discussion and Holding:  On December 19, 2010, two days after CARB’s selection of a cap-and-trade program, a number of associations—among them the Association of Irritated Residents (AIR)—filed suit against CARB. The complaint alleged that CARB failed to meet the requirements of AB 32 as well as those for the California Environmental Quality Act (CEQA). AIR asked the court to require CARB to correct the deficiencies under both AB 32 and the CEQA before allowing implementation to proceed.

AIR alleged that CARB violated the requirements of AB 32 in three ways. First, AIR claimed CARB excluded sectors of the economy from emissions controls. Thus, selecting a cap-and-trade program could not allow for a determination of whether potential reduction measures achieved maximum technologically feasible and cost effective reductions. Second, CARB did not adequately consider the total costs and benefits to the environment, economy and public health before selection of its plan. Finally, CARB did not consider—as instructed to do in AB 32—information regarding GHG emission programs throughout the United States and the world.

The Court determined that the implementation and interpretation of AB 32 was delegated to CARB; thus, on review, the Court largely deferred to CARB’s findings and interpretations under an “arbitrary and capricious” standard of review. This standard affords CARB a “wide latitude” for interpretation and implementation, and challenging a determination under this standard is an extraordinarily difficult task. In this case, AIR was unable to overcome this burden, and the Court held that CARB’s findings satisfied the requirements of AB 32.

AIR also claimed that CARB violated the requirements under the CEQA in three ways. AIR’s first claim was that CARB did not “adequately analyze the impacts of the measures described” in the plan. Second, AIR claimed that CARB did not sufficiently consider alternatives to their chosen plan. Finally, in light of the first two allegations, AIR claimed that CARB approved and implemented its plan before completing the necessary environmental impact review (EIR).

In reviewing CARB’s compliance with the CEQA, the Court used a lesser standard—abuse of discretion. Under this standard, CARB’s findings would be upheld unless there was “no substantial evidence” supporting its decision or CARB did not proceed in a manner required by law. On the first claim, the Court found that CARB did not need to provide a comprehensive analysis of the various details of the plan that would be implemented at a later date. However, on AIR’s second and third claims, the Court found CARB in violation of the CEQA. With regard to CARB’s failure to analyze alternatives, the Court noted that CARB provided five alternatives to the selected plan. The first alternative, “no project,” received 10 pages worth of discussion in the documentation supporting CARB’s plan. However, the total discussion for the other four alternatives yielded only three pages in the same document. The Court was unsatisfied that the other four alternatives received sufficient analysis, and held that CARB violated the CEQA stating that CARB’s “analysis provides no evidence to support its chosen approach.” The Court also decided the third claim against CARB. On this issue, the Court treated a resolution adopted by CARB at a hearing in December 2008 as initiating the approval of CARB’s plan. However, the finalization of CARB’s CEQA review was not finalized until May 2009. In light of CARB’s “jumping the gun,” the Court held that CARB had not complied with CEQA’s requirements.

In response to CARB’s failures under the CEQA, the Court issued an injunction preventing any further implementation of the measures contained in the selected plan until CARB has satisfied the requirements of the CEQA.

Center for Biological Diversity v. NHTSA (Ninth Circuit, 2007)

Eleven states, the District of Columbia, the City of New York, and four public interest organizations challenged a rule promulgated by the National Highway Traffic Safety Administration (NHTSA).  The rule was entitled “Average Fuel Economy Standards for Light Trucks, Model Years 2008-2011” and set corporate average fuel economy (CAFE) standards pursuant to the Energy Policy and Conservation Act (EPCA) – prior to the passage of the new energy bill (EISA).  The rule was significant in three ways.  The rule set CAFE standards for light trucks, including SUVs, minivans, and pickup trucks, for the model years 2008-2001.  The rule set new CAFE standards using its traditional method, fleet-wide average, for model years 2008-2010.  The rule also created a new CAFÉ structure that sets “varying fuel economy targets depending on vehicle size and requires manufacturers to meet different fuel economy levels depending on their vehicle fleet mix.”  The rule was challenged by the petitioners under the EPCA and the National Environmental Policy Act (NEPA).   

The petitioners’ complaint argued that the NHTSA is “arbitrary, capricious, and contrary to the EPCA because (a) the agency’s cost-benefit analysis does not set the CAFE standard at the ‘maximum feasible’ level and fails to give due consideration to the need of the nation to conserve energy; (b) its calculation of the costs and benefits of alternative fuel economy standards assigns zero value to the benefit of carbon dioxide (CO2) emissions reduction; (c) its calculation of costs and benefits of alternative fuel economy standards fails to evaluate properly the benefit of vehicle weight reduction; (d) Reformed CAFE standards will depend on manufacturer fleet mix and not guarantee a minimum average fuel economy or ‘backstop’; (e) the transition period during which manufacturers may choose to comply with either Unreformed or Reformed CAFE is contrary to the ‘maximum feasible’ requirement and unnecessary; (f) it perpetuates the ‘SUV loophole,’ which allows SUVs, minivans, and pickup trucks to satisfy a lower fuel economy standard than cars; and (g) it excludes most vehicles rated between 8,500 and 10,000 pounds gross vehicle weight (comprised mostly of large pickup trucks) from any fuel economy regulation, even though these vehicles satisfy the statutory criteria for regulation.”

The petitioners also argued that NHTSA’s Environmental Assessment (EA) under NEPA was inadequate because it fails to sufficiently examine greenhouse gas implications.  Petitioners also claimed the EA failed to analyze a reasonable range of alternatives or examine the rule’s cumulative impact.  Additionally, petitioners argued that NEPA requires that an Environmental Impact Statement be prepared as opposed to the less exhaustive EA, because a properly performed EA would have shown “significant impacts” which would then trigger the requirement of an Environmental Impact Statement.  

The court found in an unanimous decision that “the Final Rule is arbitrary and capricious, contrary to the EPCA in its failure to monetize the value of carbon emissions, failure to set a backstop, failure to close the SUV loophole, and failure to set fuel economy standards for all vehicles in the 8,500 to 10,000 gross vehicle weight rating (GVWR) class.”  The court first rejected the rule because the cost-benefit analysis did not include the cost of climate change caused by carbon dioxide.  The court also discredited contrary precedent by stating more is now known about climate change, and Mass. v EPA is more relevant than past cases where climate change science was allowed to be ignored.  The rule was then criticized for not having a “backstop” that would prevent companies from simply building bigger vehicles, which would then be allowed to produce higher emissions under the rule’s system.  The court rejected NHTSA’s arguments that this was done to account for consumer preferences stating that consumer demand cannot be the sole factor dictating the necessity of a “backstop.”  The court then challenged the “SUV loophole,” which allows SUV’s and minivans to be characterized as “light trucks” instead of “passenger automobiles” despite being predominantly used for the transportation of passengers.  The court ordered NHTSA to reexamine the classifications and provide new definitions or sufficient reasons for the SUV and minivan classification.  

The court also found “the Environmental Assessment was inadequate and that Petitioners have raised a substantial question as to whether the Final Rule may have a significant impact on the environment” because the “impact of greenhouse gas emissions on climate change is precisely the kind of cumulative impact analysis that NEPA requires agencies to conduct.”  The court found that climate change’s global nature and influence of actions outside of NHTSA’s control did not allow the agency to avoid considering the effects of the rules impact.  Additionally, the court rejected NHTSA’s argument that an EA was adequate because the CAFE standards were reducing carbon.  The court countered that the standards merely decrease the rate of carbon contribution from new cars and that NHTSA does not offer sufficient analysis to support its finding of no significant impact.  The court then remanded the case to “NHTSA to promulgate new standards as expeditiously as possible and to prepare a full Environmental Impact Statement.”

Common Law Nuisance and Tort Claims

Comer v. Murphy Oil USA, Inc.  (S.D. Miss. Aug. 30, 2007).

A group of Gulf Coast property owners filed a lawsuit against energy companies for their contributions to climate change, which the plaintiffs claimed contributed to the intensity of Hurricane Katrina.  The plaintiffs sought damages under the tort theories of unjust enrichment, civil conspiracy and aiding and abetting, public and private nuisance, trespass, negligence, and fraudulent misrepresentation and concealment.

The defendants were granted their motion to dismiss, because the court found that the plaintiffs did not have standing and raised non-justiciable questions according to the political question doctrine.  The standing decision was based on the Court’s determination that the harm was not traceable to individual defendants.  The Court’s finding of a non-justiciable question was based on the Court’s determination that more guidance from the executive and legislative branches was necessary in order for the court to create a culpability standard.  The Court also dismissed claims against parties who did not join the motion to dismiss sua sponte, or without provocation from a party before the court, due to the plaintiffs’ lack of standing. 

Procedural History: The plaintiffs thereafter filed an appeal with the Fifth Circuit Court of Appeals, which reversed the district court in part in 2009.  The reversal was vacated when the Fifth Circuit agreed to rehear the appeal en banc.  Before the rehearing, however, the appellate court lost its quorum and appellate rules required its dismissal.  Because the Fifth Circuit’s opinion had already been vacated, the 2007 district court dismissal was reinstated.  When the Supreme Court denied the plaintiffs’ request for a writ of mandamus, they filed Comer II in 2011.
See below for case outcome.

Comer v. Murphy Oil USA (United States District Court Southern District Court of Mississippi, March 20, 2012). 

The same court that dismissed Comer I dismissed Comer II  on procedural grounds, holding that the doctrines of res judicata and collateral estoppel bar claims for trespass, nuisance, and negligence against oil, coal, electric, and chemical companies for damages allegedly stemming from Hurricane Katrina. The lawsuit alleged that the companies’ activities amounted to the largest sources of GHG emissions and that climate change led to high sea temperatures and sea level rise that fueled the hurricane, which in turn damaged their property. The court held that the lawsuit was nearly identical to lawsuit the individuals had filed in 2005. The court also found that the plaintiffs lacked standing because their claims were not fairly traceable to the companies’ conduct, that the lawsuit presented a non-justiciable political question, that all of the claims were preempted by the Clean Air Act, that the claims were barred by the applicable statute of limitations, and that the plaintiffs could not demonstrate that their injuries were proximately caused by the companies’ conduct.  In the 2005 lawsuit, the district court granted defendants’ motion to dismiss. On appeal, a panel of the Fifth Circuit partially reversed, holding that plaintiffs had standing to assert their public and private nuisance, trespass, and negligence claims, and that none of these claims presented nonjusticiable political questions. The Fifth Circuit subsequently granted a motion for en banc review, but then because of a loss of quorum, the court dismissed the en banc review, which had the effect of reinstating the district court decision dismissing the case. The plaintiffs appealed for a writ of mandamus to the U.S. Supreme Court, which was denied.

Kivalina v. ExxonMobil Corp., et al. (2008)

The Kivalina complaint was filed February 26, 2008 by the native Inupiat village of Kivalina and is currently being litigated.   The complaint alleges that defendant energy and electric producers’ actions released carbon dioxide, which fueled the effects that climate change is having on the village.  Kivalina is a village of approximately 400 people located on the tip of a barrier reef about 70 miles above the Arctic Circle in Alaska.  The village must be relocated because the melting of ice which formerly acted as a wave barrier.  Without this barrier, the village is beginning to fall into the ocean.  Both the U.S. Army Corp of Engineers and the U.S. Government Accountability Office concluded that the ancestral home of the Inupiat must be relocated at an estimated cost of $95 million to $400 million.  

First, the complaint states claims of public and private nuisance under federal and, in the alternative, state law.  A nuisance occurs when a defendant unreasonably or substantially interferes with the enjoyment of one’s property.  Nuisance claims have been rejected by all previous courts in the climate change context.  The main problem with a nuisance claim for climate change damages has been showing that individual polluters’ emissions were the proximate cause of the plaintiffs’ harm and to what degree that harm was increased due to the defendant’s emissions.  These causation questions also trigger separation of powers issues as well.  

The plaintiffs hope to avoid these causation issues through the additional claims of civil conspiracy and “concert of action.”  These claims allow the plaintiff to hold multiple defendants joint and severally liable when it is impossible to determine which defendant is responsible for the individual harm.  The complaint claims the defendants “conspired to create false scientific debate about global warming in order to deceive the public.”  Methods mentioned in the filing include the using front groups, purchasing and authoring misleading advertising, funding critics of questionable expertise, denying the scientific community’s current views, and denying the effects of climate change on the Arctic.  The complaint also states that the defendants engaged in these activities despite the fact they “knew or should have known of the impacts of their emissions on global warming and on particularly vulnerable communities such as coastal Alaskan villages.”  The complaint alleges that profits and the ability to continue to profit without addressing climate change were placed above the need to prevent harm.

In order for the village to prove a civil conspiracy and concert of action, the plaintiffs are using a strategy similar to that of state governments against the tobacco companies.  States in those suits used concert of action and civil conspiracy theories based upon fraud claims based on both common law and statutory law.  Civil conspiracy only requires that two or more persons enter into an agreement to commit a wrongful act that results in harm.  Here the plaintiffs claim that the defendant corporations agreed to perpetuate a misinformation campaign on the public, which resulted in harm to the plaintiffs and the public.

A concert of action can occur in three ways.  The first requires a defendant to commit a tortious act in concert with another or pursuant to a common design.  The second occurs when the defendant knows that the other's conduct constitutes a breach of a duty and gives substantial assistance or encouragement to conduct the breach.  The third way of committing a concert of action tort occurs when one gives substantial assistance to another in accomplishing a tortious result and its own conduct, separately considered, constitutes a breach of duty to the third person.  In this instance the plaintiffs claim that the defendants acted in concert to provide misleading and false information so as to continue to cause the nuisance, global warming.  

Native Village of Kivalina v. Exxonmobil, et al. (Ninth Circuit, September 21, 2012). 

Background: This case was originally filed on February 26, 2008 (see case above).

On September 21, 2012, the Ninth Circuit unanimously affirmed the Federal District Court’s decision to dismiss the lawsuit.  In doing so, it held that federal courts are blocked from providing judicial relief in this area because when there is a federal statute that speaks directly to the issue posited by the federal common-law, (I.e. the Clean Air Act), courts must find that the federal common law has been displaced by that statute.  In his decision, Judge Sidney Thomas relied heavily on the U.S. Supreme Court’s decision in American Electric Power Co. that “Congress has directly addressed the issue of domestic greenhouse gas emissions from stationary sources and has therefore displaced federal common law.” In essence, the Ninth Circuit concluded that the regulation of greenhouse gas emissions via a federal statute (Clean Air Act) extinguished Kivalina’s federal common law public nuisance damages and abatement actions.

Significance: With the Supreme Court’s decision in American Electric Power Co., (AEP) the ability to successfully bring a common law nuisance suit associated with damage from greenhouse gas emissions was effectively curtailed.  While the AEP decision focused only on claims for injunctive relief under the federal common law of public nuisance in the context of climate change, the decision in Kivilina uses the same theory of displacement to extend the bar to cases seeking monetary damages. Now, the only possible basis for other common law nuisance suits would be state common law.

Status: In March 2013, The Kivalina village filed a petition for a writ of certiori with the U.S. Supreme Court.

American Electric Power Co. v. Connecticut (2009)


In 2004, eight states (California, Connecticut, Iowa, New Jersey, New York, Rhode Island, Vermont and Wisconsin) and New York City filed a complaint against the five largest emitters of carbon dioxide in the United States (American Electric Power, Southern Company, TVA, Xcel Energy and Cinergy Corp.) in the District Court of New York. Their complaint sought “abatement of the defendants’ ongoing contributions to a public nuisance.” The complaint relied on reports from the Intergovernmental Panel on Climate Change and the U.S. National Academy of Sciences to support the causal link between increased greenhouse gas emissions and global warming. It listed current injuries from climate change, for example, flooding in California from earlier melting of snowpack, and expected future injuries if emissions were not abated. The relief sought by the plaintiffs included requiring the defendants to cap their carbon dioxide emissions and to reduce them over time. A similar complaint was filed by three land trusts (Open Space Institute, Open Space Conservancy, and Audubon Society of New Hampshire).

The District Court dismissed the compliant ruling that the case raised a “non-justiciable political question” – an issue not well suited for the court’s to decide. It ruled that the questions raised in the complaint involved balancing the costs of reducing greenhouse gas emissions, the benefits from such actions, and the foreign policy implications and that balancing such interests required an “initial policy determination” that should first be made by another branch of government (Congress or the Executive Branch) that is better suited to such deliberations.

Second Circuit Court’s Decision

On appeal, the 2nd Circuit Court rejected the District Court’s claim that the case presented a political question better addressed by another branch of government. It stated, “Well settled principles of tort and public nuisance law provide appropriate guidance to the district court in assessing plaintiffs’ claims and that the federal courts are competent to deal with these issues.” It goes on to say that simply because a matter has political ramification, this is not a reason by itself for restricting action by the courts. The 2nd Circuit’s decision also looks at whether Congress has already spoken to the issue of limiting global warming and therefore has displaced any common law basis for action. After reviewing existing statutes, including the Clean Air Act (CAA), it concluded that no such displacement has yet occurred. Finally, the 2nd Circuit Court’s decision goes on to address the issue of standing and determined that the states do have a legitimate interest in protecting their natural resources and the health of their citizens and that the redress sought by the plaintiffs would reduce the harm alleged. The decision concludes by quoting from a water pollution case decided by the Supreme Court (Illinois v. Milwaukee, 406 U.S. 91 (1972) and applying it to greenhouse gas emissions: “It may happen that new federal laws and new federal regulations may in time pre-empt the field of federal common law of nuisance. But until that comes to pass, federal courts will be empowered to appraise the equities of the suits alleging creation of a public nuisance by greenhouse gases.” The defendants may appeal the 2nd Circuit’s decision or the case will be returned to the District Court and heard on its merits.

American Electric Power Co. v. Connecticut (U.S. Supreme Court, June 20, 2011).

The Supreme Court “granted certiorari”—chose to hear—oral arguments challenging the ruling by the 2nd Circuit Court of Appeals in Connecticut v. AEP (see above).  The suit brought by eight states and New York City (along with three land trusts) sought to use the federal common law of nuisance as grounds for obtaining reductions in carbon dioxide emissions from the utilities named in the suit. The District Court had dismissed the case on the grounds that the claim presented a “political question” that could more appropriately be addressed by another branch of government. The Second Circuit’s decision ruled that the claims do not fall within the political question exclusion and that the plaintiffs had standing to bring the case. The appeals court decision vacated the lower court’s decision and sent the case back to the District Court for further proceedings.

The case came to the Supreme Court through a petition for a writ of certiorari, which was filed by the defendant electricity producers. The Court granted the petition “without limitation.” This grant allows the Court to hear three questions that were posed by the petitioners. The questions in the petitioner’s writ were, first, whether the plaintiffs lack standing to sue; second, whether the Clean Air Act displaces the federal common law of nuisance; third, whether the claim is a political question that should be dismissed.

The U.S. Supreme Court was asked to decide whether a party can assert a federal common law nuisance claim against a company’s carbon dioxide emissions. In a unanimous (8-0) decision, the U.S. Supreme Court ruled that plaintiffs could not invoke a federal common law public nuisance claim against the electric power companies.  Building on their 2007 decision in Massachusetts v. EPA, the Court held that in passing the Clean Air Act, Congress had authorized federal regulation of greenhouse gas emissions and in doing so had effectively “occupied the field” thereby displacing  any common law claims. The Court described EPA as being far better positioned than any federal judge to develop emission control requirements to limit greenhouse gas emissions.  Importantly, the Court also made clear that any action taken pursuant to the Clean Air Act by EPA concerning greenhouse gas regulations would be subject to judicial review, clarifying that such challenges are appropriately brought under the Clean Air Act and not as federal common law nuisance claims.  The Court remanded the case to the United States Court of Appeals for the Second Circuit to consider whether the Clean Air Act also displaces the plaintiffs’ claims under state nuisance law.

Conclusions: Litigation against the harmful effects of climate change and GHG emissions cannot rely on the federal common law of nuisance because it has been displaced by the Clean Air Act.

Implications:  This case effectively marks the end of the federal common law of public nuisance in the climate change litigation context.  Specifically, the Court’s decision appears certain to lead to the dismissal of claims in which plaintiffs have invoked federal nuisance law to pursue relief for climate change-related harms.   Furthermore, because the eight Justices were equally divided on jurisdictional issues, the Court’s decision left in place the Second Circuit’s holdings that plaintiffs had standing to assert climate change injuries in federal court, and that such claims are not “political questions,” meaning they are justiciable.  Unless Congress intervenes to take away EPA’s authority to regulate greenhouse gas emissions under the CAA, the Supreme Court has barred the door for future federal common law nuisance claims.

California v. General Motors, et al., 2007 U.S. Dist. LEXIS 68547 (N.D. Cal. 2007).

California sued six automakers and claimed that the companies’ greenhouse gas emissions contributed to climate change which amounted to a public nuisance under federal common law and, alternatively, public nuisance under California law.  The state sought joint and several liability against the automakers for “creating, contributing to, and maintaining a public nuisance.”  The plaintiffs requested monetary damages, attorney’s fees, and declaratory judgment for future expenses and damages caused to California by climate change.  

The defendants replied by seeking to dismiss the case on four grounds:  (1) the case raises nonjusticiable issues; (2) the complaint fails to state a valid claim under federal common law; (3) the complaint fails to state a valid claim under California law; and (4) the California public nuisance claim is preempted by federal law.  The court found the “threshold issue” to be whether the claim raises a nonjusticiable political question outside of the court’s jurisdiction.  

Nonjusticiable or political questions are those that are better answered by the legislative or the executive branches due to concerns with a court’s ability to identify the duty, the breach of the duty, or a remedy necessary to protect the right in question.  These cases touch on questions of public policy, foreign policy, and political issues that are deemed inappropriate for courts by the Constitution.  If a decision requires the court to create law in a way that too closely resembles legislating or carry out laws in a way that overly infringes on the discretion of the executive, the court refrains from reaching a decision on the issue due to a lack of jurisdiction.  

The court cited the six formulations which indicate the existence of nonjusticiability from Baker v. Carr.  A finding of any one of these formulations results in a nonjusticiability determination.  The court found overlap among the indicators, but ultimately found the third indicator, “the impossibility of deciding without an initial policy determination of a kind clearly for nonjudicial discretion,” to be the most relevant.  The court referred to Connecticut v. AEP and cited the case throughout its analysis.  The court ultimately concluded that balancing “the competing interests of reducing global warming emissions and the interests of advancing and preserving economic and industrial development” is a “policy determination to be made by the political branches.”  The Court also cited the political branches’ actions and inactions as well as comprehensive legislative schemes under the Clean Air Act and Energy Policy and Conservation Act as further support for a finding of nonjudicial discretion in reference to the federal common law nuisance claim.  

The court distinguished the case from Massachusetts v. EPA.  First, the court noted that the Supreme Court allowed standing based on the “notion that certain constitutional principles of sovereignty afford the States ‘special solitude’ to seek judicial review of decisions by federal regulatory agencies because the States have ‘surrendered’ to the government their right to engage in certain forms of regulations.”  Second, the Court noted that the Supreme Court determined that the federal government through the EPA has the authority to regulate carbon dioxide.  Accordingly, the court reasoned that the Supreme Court allowed standing in Mass. v. EPA so that the state could challenge a policy determination as a “procedural right” to challenge an EPA administrative decision as opposed to an action in tort against private parties.  Because this case was filed against private parties, Mass. v. EPA does not offer such a procedural right for standing in this case.  

The court also found two other formulations from Baker v. Carr that were relevant to a finding of a non-justiciable political question.  For its second nonjusticiable federal question determination, the court analyzed the formulation which requires the court to determine “whether the issues before the court implicate a textually demonstrable constitutional commitment to the political branches of government.”  The court determined that the textual commitments of interstate commerce and the foreign policy to the political branches were implicated by the plaintiff’s attempt to compel damages from the defendants’ lawful worldwide sales.  Potential commerce implications could result from greenhouse gas emitters being subject to a “judicially-created tort for doing nothing more than lawfully engaging in their respective spheres of commerce with those States.”  Foreign policy implications arose from the political branches weighing in on the issue and deciding to refrain from any unilateral commitment to reducing emissions.  Because of this deliberate inaction, the court reasoned that imposing damages on emissions would result in a conflict with the political branches constitutional commitment to foreign policy issues.  For these additional reasons, the federal common law global warming nuisance tort is a nonjusticiable political question.

The court’s final Baker v. Carr indicator requires a court to decide “whether there are judicially discoverable or manageable standards available to resolve the question before it.”  The court found that determining what is “an unreasonable contribution to the sum of carbon dioxide in the Earth’s atmosphere, or determining who should bear the costs” would require a policy decision due to a lack of an existing “legal framework or applicable standards.”  Because of this indicator and the two discussed above, the court found a nonjusticiable political question and granted the motion to dismiss the federal common law global warming nuisance claim.

The court also distinguished previous transboundary nuisance cases on grounds that the remedies sought were to enjoin the nuisance rather than monetary damages, and that there is no guidance for assessing plaintiff’s contribution to warming.

The court did not reach a conclusion as to whether a federal common law nuisance claim exists due to the finding of a nonjusticiable federal question.  The court also found the state public nuisance claim to be precluded from jurisdiction because the nonjusticiability finding left the plaintiffs without a sufficiently substantial federal claim necessary to exercise supplemental jurisdiction over state law claims.  The plaintiffs have filed an appeal with the Ninth Circuit Court of Appeals.

The 2008 Candidates and Climate Change: A Guide to Key Policy Positions

For the first time, both major party candidates for the presidency are deeply concerned about global climate change and publicly support a mandatory, economy-wide cap-and-trade system for reducing the U.S. greenhouse gas (GHG) emissions that contribute to global climate change. Global climate change now occupies a place of unprecedented importance in American politics, as the debate has advanced beyond the causes of global climate change to the actions needed to address it. This guide outlines key climate positions of Sen. John McCain and Sen. Barack Obama, examines the records of their respective vice-presidential nominees, and details relevant portions of the Republican and Democratic Party platforms, with links to related resources focused on critical climate change policy issues.

As a non-partisan policy center, the Center will not be endorsing a specific candidate, and will be working to inform the policies of whoever is elected president. This brief guide discusses a few notable details of the presidential contenders' plans to combat global climate change. A detailed, bullet-point summary of the candidates' policies is contained in the appendix.

GHG Cap and Trade as Primary Method of Reducing GHG Emissions

Both Sen. Obama and Sen. McCain support a mandatory, economy-wide GHG cap-and-trade program as a primary tool for reducing U.S. GHG emissions. In a cap-and-trade system, the government sets a declining annual cap on total GHG emissions, requires facilities that emit GHGs to acquire one "allowance" for each ton of their emissions, and allows the facilities to buy and sell allowances from each other or from the government (e.g., at an auction). In this way, while government establishes the environmental objective, industry, through the marketplace, decides the most cost effective way to achieve it.

Sen. McCain's proposal for a cap-and-trade program incorporates several details drawn from the cap-and-trade bills he co-authored with Sen. Joseph I. Lieberman (ID-CT) in the Senate in 2003, 2005, and 2007. Sen. Obama cosponsored the 2005 and 2007 McCain-Lieberman bills, but has taken different positions on two aspects of a cap-and-trade program: the pace of GHG reductions and the method of initially distributing GHG allowances.

As GHGs accumulate in the atmosphere, they adversely affect the climate for decades. Unfortunately, the United States' annual GHG emissions have been rising steadily – they were 14.7% higher in 2006 than they were in 1990. Sen. McCain's plan calls for limiting U.S. GHG emissions at the 2005 levels by 2012; at 1990 levels in 2020 (15% below 2005 levels); and at 22% below 1990 levels in 2030 (34% below 2005 levels).

Sen. Obama has not specified short- and mid-term goals, but materials on his campaign's web site state that he "will start reducing emissions immediately in his administration by establishing strong annual reduction targets."

In the longer term, Sen. Obama has called for an 80% reduction of U.S. GHG emissions below 1990 levels by 2050, while Sen. McCain's plan calls for a 60% reduction below 1990 levels by 2050.

Initial allowance distribution is among the most contentious elements in the design of a cap-and-trade program. While allowance distribution does not affect the environmental integrity of the program (the quantity of GHGs emitted is determined by the cap levels mentioned above), it does have several other important policy implications. Under a cap-and-trade program, there are several methods by which allowances could be initially put into the market. Among other things, allowances could be: given for free to emitting facilities or manufacturers facing higher energy costs to assist the transition to low-carbon energy sources; auctioned to raise revenue for a variety of purposes, including protecting low-income consumers from higher energy costs, aiding the transition of workers, subsidizing the development and deployment of low-carbon energy technologies, and managing the physical impacts of global climate change; or auctioned to provide revenue for the general treasury that could be used to offset tax cuts or to reduce the federal deficit, for example. Any combination of these methods may be employed.

Sen. Obama has proposed the auction of 100% of GHG emissions allowances, with an estimated $250 billion a year in auction revenues being used for a variety of purposes, including an investment of $150 billion over 10 years to develop and deploy lower-emission energy supplies and create new jobs. Sen. McCain has been less specific on the subject of initial allowance distribution. His campaign's website states that his program would eventually auction allowances, and would "work to maximize the amount of allowances that are auctioned by 2050." Similarly, the McCain-Lieberman bills would require the U.S. Environmental Protection Agency to determine how best to distribute allowances.



Complementary Policies to Slow or Reduce GHG Emissions

Cap-and-trade is essential to reducing U.S. GHG emissions, but by itself cap and trade will not be sufficient to bring domestic and international emissions down to safe levels. Transportation policies, building codes, energy efficiency, and low-carbon energy generation are just a few of the areas that will need to be part of a successful comprehensive climate change policy.

Sen. McCain strongly favors dramatically expanded nuclear power generation. He has called for 45 new nuclear reactors by 2030 and for 100 new nuclear plants in the long term. Sen. Obama is open to increasing nuclear generation, saying, "it is unlikely that we can meet our aggressive climate goals if we eliminate nuclear power as an option," but "before an expansion of nuclear power is considered, key issues must be addressed including: security of nuclear fuel and waste, waste storage, and proliferation."

Both candidates support research, development and deployment (RD&D) of carbon capture and sequestration (CCS) technology for coal-fired power plants. CCS is also sometimes referred to as "clean coal technology." Sen. McCain has called for $2 billion per year for CCS RD&D, while Sen. Obama would direct the Department of Energy to enter into public-private partnerships to develop five commercial-scale coal?fired plants with CCS.

The candidates disagree over a renewable portfolio standard (RPS) (also called a renewable energy standard [RES]), which would set a federal mandate for the percentage of electricity consumed in the U.S. that must come from renewable sources. Sen. Obama favors an RPS of 10% of all consumed energy by 2012. Sen. McCain opposes such a mandate, supporting instead tax incentives to encourage renewable energy production.

Both candidates have made recommendations that could reduce GHG emissions from the transportation sector. Sen. McCain would establish a "Clean Car Challenge," a tax credit of $5,000 for every consumer who buys a zero-carbon emission car; McCain would also establish a $300 million prize for the development of advanced battery technology for plug-in hybrid and fully electric automobiles. Sen. Obama proposes a $7,000 tax credit for the purchase of advanced technology vehicles, and has set a goal of 1 million plug-in electric vehicles on the road by 2015. Both candidates support expanded production of flexible fuel vehicles (FFVs) ¬¬– American automakers are already committed to make 50% of their cars FFVs by 2012, and Sen. Obama pledges to make 100% of all new cars are FFVs by 2012, while Sen. McCain "calls on automakers to make a more rapid and complete switch to FFVs."

Changing the vehicles we drive is one important way to reduce GHG emissions from transportation, but addressing the emissions from transportation fuels themselves is also critical. To that end, Sen. Obama would establish a national Low Carbon Fuel Standard (LCFS), which would, starting in 2010, require fuel suppliers to reduce the carbon content of their fuel by 5% by 2015, and by 10% by 2020. Sen. Obama would also increase fuel economy standards by 4% a year. Sen. McCain would "effectively enforce" existing fuel economy standards, and would eliminate mandates, subsidies, tariffs and price supports that focus only on corn-based ethanol, which would "level the playing field for all alcohol-based fuels," including cellulosic ethanol.

Both candidates recognize that improving energy efficiency across the economy can be a powerful tool for reducing GHG emissions. Sen. McCain would apply higher efficiency standards to new or retrofitted buildings leased or purchased by the Federal government, which is currently the largest energy consumer in the world, and occupies 3.3 billion square feet of space worldwide. Sen. McCain would also promote investment to upgrade the national electricity grid, and supports deploying smart metering technology. Sen. Obama would set a national electricity efficiency goal of reducing demand by 15% from DOE's projected 2020 levels. Sen. Obama would also set a goal of making all new buildings carbon-neutral or zero-emission by 2030, and set a national goal of improving new building efficiency by 50% and existing building efficiency by 25% over the next decade. Like Sen. McCain, Sen. Obama pledges to reduce Federal energy consumption, improving energy efficiency in all new Federal buildings by 40% within 5 years, and ensuring that all new Federal building are zero-emitting by 2025. Sen. Obama also pledges to invest in a smart grid, and to incentivize states to adopt regulations allowing utilities to decouple profits from increased energy usage.



International Climate Agreements

The United Nations Framework Convention on Climate Change (UNFCCC) process is actively moving towards a new international climate change agreement, with an ambitious target completion date of December 2009. Both candidates have expressed their intent to actively engage in these negotiations, and their approach to international climate policy is profoundly different from the current administration.

Both candidates have also expressed their intent to provide incentives for developing countries to reduce their GHG emissions. Sen. Obama would create a technology transfer program within the Department of Energy to transfer lower-polluting American energy technology to the developing world to fight climate change; Sen. McCain would establish "government incentives and partnerships for sales of clean tech to developing countries."

Regarding major emerging economies, such as China and India in particular, Sen. McCain would "provide incentives for rapid participation by India and China, while negotiating an agreement with each," while Sen. Obama would "cooperate with China and India to reduce demand for oil," and in general "ensure the U.S. works with developing countries on climate change," including "confronting deforestation and promoting carbon sequestration."

In addition, Sen. Obama "would create a Global Energy Forum – based on the G8+5, which include all G-8 members plus Brazil, China, India, Mexico and South Africa – of the world's largest emitters to focus exclusively on global energy and environmental issues." McCain has not publicly proposed an additional international process.

EPA Regulations for CO2

Updated on October 31, 2008

The Supreme Court, in the 2007 case Massachusetts v. E.P.A., ruled that the government has the authority to regulate greenhouse gas (GHG) emissions under the current Clean Air Act, overruling the Bush Administration argument that it did not have such authority. Despite the ruling, the Administration has declined to regulate GHGs, and maintains that the Clean Air Act is too unwieldy an instrument to use for GHG regulation.

The campaigns of both Sen. Obama and Sen. McCain have said their candidate prefers reducing GHG emissions through Congressional legislation than through the Clean Air Act's regulatory mechanisms. But in the absence of such Congressional action, top advisers to both McCain and Obama have said their candidate would comply with a 2007 Supreme Court ruling that allows the EPA to regulate carbon dioxide (CO2) and other GHGs.

"The EPA is obligated to move forward in the absence of Congressional action," Jason Grumet, Sen. Obama's energy advisor said. "If there's no action by Congress in those 18 months, I think any responsible president would want to have the regulatory approach." [Bloomberg, October 16]

Sen. Obama would, "initiate those rulemakings," Grumet said. "He's not going to insert political judgments to interrupt the recommendations of the scientific efforts."

Obama campaign officials have since said Grumet was explaining that producing complex government regulations generally takes about 18 months. [E&ENews PM, October 29]

Similarly, top McCain adviser Douglas Holtz-Eakin said McCain, if elected, would comply with the Supreme Court ruling on GHGs. [E&ENews PM, October 29]

However, two McCain advisers' have expressed the candidate's preference for regulating the gas through Congressional legislation—former Central Intelligence Agency director and current McCain adviser James Woolsey said on October 6 that new rules may conflict with Congressional efforts, while policy adviser Rebecca Jensen Tallent said in August that McCain prefers a bill debated by Congress rather than regulations "established through one agency where one secretary is getting to make a lot of decisions." [Bloomberg, October 16]



On the Campaign Trail

Sen. John McCain:

"We must use all resources and develop all technologies necessary to rescue our economy from the damage caused by rising oil prices and restore the health of our planet." – Speech accepting the Republican nomination for President, Sep. 5, 2008.

"We now know that fossil fuel emissions, by retaining heat within the atmosphere, threaten disastrous changes in climate. No challenge of energy is to be taken lightly, and least of all the need to avoid the consequences of global warming.

"Over time, we must shift our entire energy economy toward a sustainable mix of new and cleaner power sources. This will include some we use already, such as wind, solar, biofuels, and other sources yet to be invented. It will include a variety of new automotive and fuel technologies, clean-burning coal and nuclear energy, and a new system of incentives, under a cap-and-trade policy, to put the power of the market on the side of environmental protection. To make the great turn away from carbon-emitting fuels, we will need all the inventive genius of which America is capable. We will need as well an economy strong enough to support our nation's great shift toward clean energy.

"Global warming presents a test of foresight, of political courage, and of the unselfish concern that one generation owes to the next. We need to think straight about the dangers ahead, and meet the problem with all the resources of human ingenuity at our disposal. We Americans like to say that there is no problem we can't solve, however complicated, and no obstacle we cannot overcome if we meet it together. I believe this about our country. And now it is time for us to show those qualities once again." – Speech to the Clinton Global Initiative, Sep. 25, 2008.

"… [President Bush] and I have not seen eye to eye on many issues. We've disagreed over energy policy and climate change …" – June 3, 2008.

"We have many advantages in the fight against global warming, but time is not one of them. Instead of idly debating the precise extent of global warming, or the precise timeline of global warming, we need to deal with the central facts of rising temperatures, rising waters, and all the endless troubles that global warming will bring. We stand warned by serious and credible scientists across the world that time is short and the dangers are great. The most relevant question now is whether our own government is equal to the challenge.

"There are vital measures we can take in the short term, even as we focus on long-term policies to mitigate the effects of global warming … Each one of the consequences of climate change will require policies to protect our citizens, especially those most vulnerable to violent weather. Each one will require new precautions in the repair and construction our roads, bridges, railways, seawalls and other infrastructure. Some state and local governments have already begun their planning and preparation for extreme events and other impacts of climate change. The federal government can help them in many ways, above all by coordinating their efforts, and I am committed to providing that support.

"To lead in this effort, however, our government must strike at the source of the problem ¬– with reforms that only Congress can enact and the president can sign. We know that greenhouse gases are heavily implicated as a cause of climate change. And we know that among all greenhouse gases, the worst by far is the carbon-dioxide that results from fossil-fuel combustion. Yet for all the good work of entrepreneurs and inventors in finding cleaner and better technologies, the fundamental incentives of the market are still on the side of carbon-based energy. This has to change before we can make the decisive shift away from fossil fuels.

"For the market to do more, government must do more by opening new paths of invention and ingenuity. And we must do this in a way that gives American businesses new incentives and new rewards to seek, instead of just giving them new taxes to pay and new orders to follow. The most direct way to achieve this is through a system that sets clear limits on all greenhouse gases, while also allowing the sale of rights to excess emissions. And this is the proposal I will submit to the Congress if I am elected president ¬– a cap-and-trade system to change the dynamic of our energy economy." – June 25, 2008.



Sen. Barack Obama:

"I will build new partnerships to defeat the threats of the 21st century: terrorism and nuclear proliferation; poverty and genocide; climate change and disease." – Speech accepting the Democratic nomination for President, Aug. 28, 2008.

"No single issue sits at the crossroads of as many currents as energy. Our dependence on oil and gas funds terror and tyranny; it has forced families to pay their wages at the pump; and it puts the future of our planet in peril. This is a security threat, an economic albatross, and a moral challenge of our time. The time to debate whether climate change is manmade has past – it's time, finally, for America to lead.

"The first commitment that I'll make today is setting a goal of an 80 percent reduction in greenhouse gas emissions by 2050.

"To do our part, we'll implement a cap-and-trade program so that there's a price for pollution, and resources to transform our energy economy. I've proposed an investment of $150 billion in alternative energy over ten years, which will create millions of jobs and break the cycle of our addiction to oil. We need to do more than drill. Now is the time to develop every form of alternative energy – solar, wind, and biofuels, as well as technologies that can make coal clean and nuclear power safe. We need to raise fuel economy standards, put more plug-in hybrid cars on the road, and find new ways to be energy efficient.

"Abroad, the United States must get off the sidelines. We'll reach out to the leaders of the biggest carbon emitting nations and ask them to join a new Global Energy Forum to lay the foundation for the next generation of climate protocols. We'll build an alliance of oil-importing nations, and work together to reduce our demand, and break the grip of OPEC. And as we develop clean energy, we should share technology and innovations with the nations of the world.

"This effort to confront climate change will be part of our strategy to alleviate poverty. Because we know that it is the world's poor who will feel – and who may already be feeling – the affect of a warming planet. If we fail to act, famine could displace hundreds of millions, fueling competition and conflict over basic resources like food and water."

– Speech to the Clinton Global Initiative, Sep. 25, 2008.

"As President, I will set a hard cap on all carbon emissions at a level that scientists say is necessary to curb global warming ¬– an 80% reduction by 2050. To ensure this isn't just talk, I will also commit to interim targets toward this goal in 2020, 2030, and 2040. These reductions will start immediately, and we'll continue to follow the recommendations of top scientists to ensure that our targets are strong enough to meet the challenge we face.

"In addition to this cap, all polluters will have to pay based on the amount of pollution they release into the sky. The market will set the price, but unlike the other cap-and-trade proposals that have been offered in this race, no business will be allowed to emit any greenhouses gases for free. Businesses don't own the sky, the public does, and if we want them to stop polluting it, we have to put a price on all pollution. It's time to make the cleaner way of doing business the more profitable way of doing business."

"…to combat climate change [I will] call on businesses, government, and the American people to make America 50% more energy efficient by 2030. This is by far the fastest, easiest, and cheapest way to curb our emissions and save money at the same time. Since DuPont implemented an energy efficiency program in 1990, the company has significantly reduced its pollution and cut its energy bills by $3 billion, and cities like Keene and Portland, Oregon have led in meeting new efficiency standards. There is no reason the rest of America can't do the same.

"We will start by dramatically improving the efficiency of our buildings, which currently account for nearly half of all carbon emissions in America today. When I am President, we'll set a goal of making our new buildings 50% more efficient within several years. The federal government will lead by making all of its buildings carbon neutral by 2025. And I will set a national goal of making all new buildings in America carbon neutral by 2030." – October 8, 2007.

"One of the most dangerous weapons in the world today is the price of oil...this immediate danger is eclipsed only by the long-term threat from climate change, which will lead to devastating weather patterns, terrible storms, drought, and famine. That means people competing for food and water in the next fifty years in the very places that have known horrific violence in the last fifty: Africa, the Middle East, and South Asia. Most disastrously, that could mean destructive storms on our shores, and the disappearance of our coastline." – July 15, 2008.

"Our changing climate is placing our planet in peril." – Aug. 4, 2008.



The Vice-Presidential Candidates

Sen. Joseph R. Biden, Jr. (D-DE):

Sen. Biden is a long-time supporter of climate action, having voted for the 2003 and 2005 McCain-Lieberman bills, and having strongly advocated for U.S. engagement in international climate change treaty negotiations. In 2003 and 2005 with Senator John F. Kerry (D-MA), and in 2005 and 2007 with Sen. Richard Lugar (R-IN), he cosponsored a nonbinding resolution calling for U.S. participation in international climate change negotiations. Sen. McCain voted for this resolution in 2005.

Sen. Biden also cosponsored, with Senators Lugar and Hagel (R-NE), legislation which would authorize $2 billion for the Clean Technology Fund, an initiative of President George W. Bush, which would be administered by the World Bank to promote lower- and zero-carbon energy production projects in the developing world.


Gov. Sarah Palin (R-AK):

While Gov. Palin has taken state and regional action on climate change ¬– such as establishing a special Climate Change Sub-Cabinet, and making Alaska an observer of the Western Climate Initiative (in which seven other U.S. states and four Canadian provinces are developing a mandatory cap-and-trade program to reduce the region's greenhouse gas emissions) ¬– she has also expressed skepticism about the extent to which human activities are contributing to global climate change and associated impacts. Alaska has not as yet adopted any measures to reduce its GHG emissions.

In December 2007, she told the Fairbanks Daily News-Miner, "I'm not an Al Gore, doom-and-gloom environmentalist blaming the changes in our climate on human activity. But I'm not going to put my head in the sand and pretend there aren't changes."

In a January 5, 2008, op-ed in The New York Times Palin treads this line. She argued against listing polar bears as an endangered species because of threats to their habitats caused by global climate change, writing "the possible listing of a healthy species like the polar bear would be based on uncertain modeling of possible effects. This is simply not justified."

In August 2008, before Sen. McCain selected her as his running mate, she told Newsmax.com "A changing environment will affect Alaska more than any other state, because of our location. I'm not one though who would attribute it to being man-made."

On September 3, in her first interview as the Vice-Presidential nominee, however, she told ABC News, "I believe that man's activities certainly can be contributing to the issue of global warming, climate change."

A September 30, 2008, interview for CBS News with Katie Couric featured an extensive exchange on climate change and cap and trade:

Couric: If [climate change] is not man-made, then one might wonder, well, how can human beings contribute to a solution?

Gov. Palin: Well, human beings certainly are contributing to pollution today. And to some adverse effects on the environment. And it's all of our jobs to do to clean things up. And that's what we're committed to doing."

Couric: So you do believe … that man is contributing to global warming, because you just said they're causing pollution. Of course, pollution causes global warming.

Gov. Palin: I believe that there are a lot of causes. And there is one effect. And one is changes in the climate. And there are things that we can do to make sure we're cleaning up the environment. I also formed an integrity office that solely is focused on petroleum, on pipelines, on those things that we do up there in Alaska to contribute to the U.S. domestic supply of energy.

Where we can focus solely on environmental protections. There are a lot of things that I've done there in that arena of environmental protection that have kind of ticked off some in my own party thinking that I went too far. But I've always been of the mind that, you know, we gotta prove that we can do this right. Safely, ethically, environmentally friendly developments, or we're not gonna be allowed to unlock our lands and tap these supplies.

Couric: John McCain proposed legislation calling for mandatory caps on global warming gases or CO2 emissions. Do you agree with that?

Gov. Palin: I support his position on that. Absolutely.

Couric: But he somewhat backtracked on the campaign trail saying it wouldn't, they wouldn't, the caps wouldn't be mandatory, they'd be voluntary. So what do you think? Do you think voluntary caps go far enough? Or they should be mandatory?

Gov. Palin: He's got a good cap and trade policy that he supports. And details are being hashed out even right now. But, in principle, absolutely, I support all that we can do to reduce emissions and to clean up this planet. And john McCain is right on board with that.

Couric: Voluntary or mandatory in your view?

Gov. Palin: We're gonna keep working on how it can be implemented to actually make sense and make a difference.



The Party Platforms

The Republican Party:

"As part of a global climate change strategy, Republicans support technology-driven, market-based solutions that will decrease emissions, reduce excess greenhouse gases in the atmosphere, increase energy efficiency, mitigate the impact of climate change where it occurs, and maximize any ancillary benefits climate change might offer for the economy.... Republicans caution against the doomsday climate change scenarios peddled by the aficionados of centralized command-and-control government.... [W]e will insist on reasonable policies that do not force Americans to sacrifice their way of life or trim their hope and dreams for their children. This perspective serves not only the people of the United States but also the world's poorest peoples, who would suffer terribly if climate change is severe – just as they would if the world economy itself were to be crippled. We must not allow either outcome."

The Democratic Party:

"We will help pay for [clean energy programs] by dedicating a portion of the revenues generated by an economy-wide cap-and-trade program – a step that will also dramatically reduce our greenhouse gas emissions and jumpstart billions in private capital investment in a new energy economy."

  • Ensure the U.S. works with developing countries on climate change.
  • Confront deforestation and promote carbon sequestration.


Sen. John McCain

Candidate's website

Sen. John McCain's Cap and Trade Policy:

  • Greenhouse Gas Emission Targets And Timetables:
    • 2005 levels in 2012 (18% above 1990 levels)
    • 1990 levels in 2020 (15% below 2005 levels)
    • 22% below 1990 levels in 2030 (34% below 2005 levels)
    • 60% below 1990 levels in 2050 (66% below 2005 levels)
  • Coverage:
    • Electric power, transportation fuels, commercial businesses, and industrial businesses.
    • Just below 90% of all emissions. Small businesses would be exempt. Initially, participants would be allowed to either make their own GHG reductions or purchase "offsets" – financial instruments representing a reduction, avoidance, or sequestration of greenhouse gas emissions practiced by other activities, such as agriculture – to cover 100 percent of their required reductions. Offsets would only be available through a program dedicated to ensure that all offset GHG emission reductions are real, measured and verifiable. The fraction of GHG emission reductions permitted via offsets would decline over time.
  • Allocation and Auction:
    • "Emissions permits will eventually be auctioned to support the development of advanced technologies. A portion of the proceeds of these auctions will be used to support a diversified portfolio of research and commercialization challenges, ranging from carbon capture and sequestration, to nuclear power, to battery development. Funds will also be used to provide financial backing for a Green Innovation Financing and Transfer (GIFT) to facilitate commercialization."
    • "A portion of auction proceeds" will also go to "reduce impacts on low-income American families."
    • "Early allocation of some emission permits on sound principles. This will provide a significant amount of allowances for auctioning to provide funding for transition assistance for consumers and industry. It will also directly allocate sufficient permits to enable the activities of a Climate Change Credit Corporation, the public-private agency that will oversee the cap and trade program, provide credit to entities for reductions made before 2012, and ease transition for industry with competitiveness concerns and fewer efficiency technology options."
    • "A commission will also be convened to provide recommendations on the percentage of allowances to be provided for free and the percentage of allowances to be auctioned, and develop a schedule for transition from allocated to maximum auctioned allowances. Cap-and-trade system will also work to maximize the amount of allowances that are auctioned off by 2050."
  • Cost-containment:
    • Full banking and borrowing.
    • Initially, firms will be able to use domestic and international offsets for 100% of their compliance obligation.
    • Trading will be integrated with other international markets.
    • A Strategic Carbon Reserve will be established as a national source of permits "during periods of economic duress."
  • International:
    • "John McCain will engage the international community in a coordinated effort by:
      • Actively engaging to lead United Nations negotiations;
      • Permitting America to lead in innovation, capture the market on low-carbon energy production, and export to developing countries – including government incentives and partnerships for sales of clean tech to developing countries;
      • Provide incentives for rapid participation by India and China, while negotiating an agreement with each."
  • Adaptation:
    • "John McCain will develop a climate change adaptation plan.
    • A comprehensive approach to addressing climate change includes adaptation as well as mitigation.
    • An adaptation plan should be based upon national and regional scientific assessments of the impacts of climate change.
    • An adaptation plan should focus on implementation at the local level which is where impacts will manifest themselves.
    • A comprehensive plan will address the full range of issues: infrastructure, ecosystems, resource planning, and emergency preparation."

The Lexington Project for Energy Independence

  • 45 new nuclear reactors by 2030.
  • Long-term goal of 100 new nuclear plants.
  • $2 billion/year to clean coal RD&D.
  • Clean Car Challenge to automakers: The first zero-emission car will earn $5,000 tax credit for each customer. For other vehicles, the lower the carbon emissions, the higher the tax credit.
  • Goal of a "swift conversion of American vehicles away from oil."
  • $300 million prize for advanced vehicle battery technology.
  • Renewables to be incentivized through cap-and-trade program.



Press Release: Offset Quality Initiative Releases White Paper


News Release: For Immediate Release — July 28, 2008

Alexia Kelly, The Climate Trust, 541-514-3633
Tom Steinfeldt, Pew Center on Global Climate Change, 703-516-4146


Group Receives Major Grant from the Energy Foundation

PORTLAND and WASHINGTON, D.C. — The Offset Quality Initiative (OQI) will release a white paper today in San Diego at a briefing to be held before the opening of the Western Climate Initiative stakeholder meeting. Titled “Ensuring Offset Quality: Integrating High Quality Greenhouse Gas Offsets Into Cap-and-Trade Policy,” the document offers policymakers practical recommendations regarding the integration of greenhouse gas offsets into emerging regulatory systems at the state, regional and federal levels. OQI, a coalition of six leading non-profit organizations—The Climate Trust, Pew Center on Global Climate Change, California Climate Action Registry, Environmental Resources Trust, Greenhouse Gas Management Institute, and The Climate Group—was founded in November 2007 to provide leadership on GHG offset policy and best practices. 

“The availability of high-quality offsets is key to containing the cost of climate policy while delivering real greenhouse gas emission reductions,” said Eileen Claussen, President of the Pew Center on Global Climate Change. “A rigorous and adaptable offset program design can ensure that offsets play a valuable role in an effective cap-and-trade system. OQI’s work will assist policymakers seeking to develop core components of a credible offsets program.”

In addition to regulatory design guidelines, the white paper addresses the key criteria for offset quality and discusses offset project types most appropriate for inclusion in emerging regulatory systems. OQI member organizations will discuss their recommendations with policymakers and other stakeholders over the next several weeks, beginning with today’s briefing in San Diego.

“Establishing confidence in the environmental integrity of offsets is critical for the successful launch and acceptance of future cap and trade regulatory systems.  The goal of our paper is to provide policymakers with well-conceived and comprehensive recommendations for offset program design based on the collective knowledge and experience of the OQI members.  Each nonprofit member of the coalition is a well-respected and established organization in climate change and brings valuable experience and knowledge to the group,” said Gary Gero, President of the California Climate Action Registry.

OQI recently received a one-year grant of $235,000 from the Energy Foundation to support its work. “We were excited and honored to receive the grant,” said Mike Burnett, Executive Director of The Climate Trust, which was awarded the grant on behalf of OQI. “This generous support from the Energy Foundation highlights the need for the unique work and perspective of OQI. We will use the funds to continue to advance sound greenhouse gas offset policy.”

About the Offset Quality Initiative
The Offset Quality Initiative (OQI) was founded in November 2007 to provide leadership on greenhouse gas offset policy and best practices. OQI is a collaborative, consensus-based effort that brings together the collective expertise of its six nonprofit member organizations: The Climate Trust, Pew Center on Global Climate Change, California Climate Action Registry, the Environmental Resources Trust, Greenhouse Gas Management Institute, and The Climate Group.

The four primary objectives of the Offset Quality Initiative are:

  • To provide leadership, education, and expert analysis on the issues and challenges related to the design and use of offsets in climate change policy.
  • To identify, articulate, and promote key principles that ensure the quality of greenhouse gas emission offsets.
  • To advance the integration of those principles in emerging climate change policies at the state, regional, and federal levels.
  • To serve as a source of credible information on greenhouse gas offsets, leveraging the diverse collective knowledge and experience of OQI members.
