States Sue U.S. Environmental Protection Agency

Promoted in Energy Efficiency section: 

On April 2, 2008, 12 states, the District of Columbia, two cities, and several environmental groups sued the U.S. Environmental Protection Agency over its failure to regulate greenhouse gas emissions from motor vehicles. The states and other petitioners are asking the U.S. Circuit Court of Appeals for the District of Columbia to force the EPA to issue within 60 days its formal determination of the public health impacts from GHG emissions. In filing their suit, the plaintiffs cited the Supreme Court’s April 2007 decision in Massachusetts et al v. EPA, in which the Court ruled that the EPA is authorized to regulate greenhouse gases under the federal Clean Air Act, and must consider doing so unless it can demonstrate that these gases do not contribute to climate change that harms human health and welfare. Since the Supreme Court’s ruling, the EPA has not issued any formal language or rules for the regulation of CO2 or other greenhouse gases. The states joining the lawsuit include California, Connecticut, Illinois, Maine, Massachusetts, New Jersey, New Mexico, New York, Oregon, Rhode Island, Vermont, Washington, Arizona, Delaware, Iowa, Maryland and Minnesota.

Kansas Governor Forms Climate Change Advisory Group, Initiates Climate Action Plan

Promoted in Energy Efficiency section: 

On March 21, 2008, Governor Kathleen Sebelius signed Executive Order 08-03, which establishes the Kansas Energy and Environmental Policy Advisory Group. The new 25-member Advisory Group will recommend steps that the state can take to reduce its greenhouse gas emissions, as well as a proposed timetable for implementation of those recommendations. The Advisory Group will consider issues such as community economic development and electricity generation, and opportunities for diversifying the state’s energy portfolio. Kansas joins 36 other states in formulating a climate action plan. Having previously denied permits to two new coal-fired power plants, Governor Sebelius also vetoed Senate Bill 327, which would have allowed construction of the plants to continue.

Vermont Governor Signs Efficiency Bill

Promoted in Energy Efficiency section: 

On March 20, 2008, Governor Jim Douglas signed into law Senate Bill S.209, the Energy Efficiency and Affordability Act of 2008.  The act establishes a statewide goal of producing 25 percent of the energy consumed in the state from renewable sources, particularly Vermont’s farms and forests, by 2025.  The act increases the use of net metering in the state and expands the use of biodiesel in state buildings and the state’s vehicle fleet.  It also includes new funding for efficiency programs that will coordinate expertise, technical assistance, and resources, as well as tax incentives designed to help promote investment in renewable energy resources.  In addition, the act establishes a fuel efficiency fund, financed by revenues from the sale of the state’s emission allowances under the Regional Greenhouse Gas Initiative’s (RGGI) cap-and-trade program.

Washington Governor Signs Climate Change Bill

Promoted in Energy Efficiency section: 

On March 13, 2008, Washington Governor Christine Gregoire signed into law House 2815, the Climate Change Framework/Green-Collar Jobs Act. The bill calls for reductions from the state’s transportation sector, Washington’s largest contributor to greenhouse gas emissions, by cutting vehicle miles traveled by 18 percent by 2020, 30 percent by 2035, and 50 percent by 2050. The bill directs state agencies to provide training and incentives in an effort to attract green-collar jobs to Washington. It also requires the state’s largest emitters to inventory and report their emissions beginning in 2010, and directs relevant state agencies to continue working regionally with other Western states and Canadian provinces to design and implement a market-based system to reduce greenhouse gas pollution from major sectors of the economy. Statewide targets adopted in 2007 require a reduction of greenhouse gas emissions to 1990 levels by 2020, 25 below 1990 levels by 2035, and 50 percent below 1990 levels by 2050. This new bill directs the Department of Ecology to submit a comprehensive plan to the legislature, outlining specific measures to reach these targets, and to provide an update on Washington’s ongoing participation in the Western Climate Initiative multisector cap-and-trade design process.

The Greenhouse Gas Accord announced by ten Midwestern governors in November 2007 involves nearly one fourth of U.S. greenhouse gas emissions in a regional agreement to improve energy security and design a greenhouse gas (GHG) reduction program. Among the strategies described in this accord is the use of a market-based, multi-sector cap-and-trade mechanism to reduce emissions. As the Midwest explores options for such a program, it will face a variety of design choices regarding program goals, costs, and equity. This paper is intended to guide many of these choices by describing some of the options available.

This paper begins with a general overview of the basic building blocks of cap and trade, followed by a discussion of the potential scope of coverage of a program, including what entities might be regulated and which emissions. The paper then focuses on how to set the initial emissions cap and the trajectory for emissions reductions under a potential program. An examination of the options for distributing allowances, or permits to emit, follows. The document then explores how a program might grant early reduction credits, offer project-based offset credits, and provide other potential cost-containment measures. The potential for linking with other similar programs is then briefly discussed.


New Mexico Governor Signs Energy Efficiency Bill

Promoted in Energy Efficiency section: 

On February 27, 2008, New Mexico Governor Bill Richardson signed into law House Bill 305, which strengthens the state’s existing Efficient Use of Energy Act. The bill provides financial incentives to electric and gas utilities to reduce their customers’ energy consumption. HB 305 decouples utility revenues from electricity sales, allowing utilities to earn profits by investing in demand-side efficiency projects rather than simply building new power plants to meet demand. State regulators are now required to approve higher profits for energy-efficiency programs that are more cost-effective than building new electric generation plants. HB 305 also requires electric utilities to achieve energy-efficiency savings of at least five percent of 2005 sales by 2014, and 10 percent by 2020. New Mexico’s Public Regulation Commission (PRC) may set alternative requirements if the utility demonstrates it cannot meet those minimum requirements. The bill further strengthens the state’s energy efficiency measurement and verification requirement, and requires an assessment of utilities’ energy efficiency programs every three years by an independent program evaluator.

Participants Call for a Shared Approach to Climate Change Policy

The Pew Center on Global Climate Change, in conjunction with the Pew Center on the States, convened its annual conference February 25-26 that focused on innovative approaches to climate change. This year’s conference addressed critical issues between states and the federal government in developing policies to reduce greenhouse gas emissions.

The conference featured speeches by Minnesota Gov. Tim Pawlenty, New Mexico Gov. Bill Richardson, and Sen. John Kerry of Massachusetts. Pawlenty and Richardson, considered possible Republican and Democratic vice presidential contenders respectively, highlighted their states’ clean energy efforts and the different roles state and federal governments can play to advance emission reduction policies.   In his remarks, Kerry cited the immediate need for federal leadership on climate change and encouraged grassroots efforts at state and local levels to pressure federal officials to act.

The two-day conference included several panel discussions about key climate change topics confronting state and federal leaders. Significant discussion focused on the design of a cap-and-trade program, which is slated for implementation in three regional programs involving 23 states and is the centerpiece of pending legislation in Congress. The regional efforts – the Regional Greenhouse Gas Initiative in the Northeast; the Western Climate Initiative; and the Midwestern Regional Greenhouse Gas Reduction Accord – are viewed largely as laboratories for a future national climate plan.

“We need to strike a balance between what states and the federal government do best, and reflect this in a strong national climate policy,” said Eileen Claussen, President of the Pew Center on Global Climate Change. “States are demonstrating their unique ability to serve as proving grounds for sensible climate action. But the federal government must show leadership if we are to achieve the most cost-effective and comprehensive path to reduce emissions.”

Additional topics addressed at the conference included low-carbon transportation solutions, electricity options, and smart growth. Adaptation, an increasingly important concern for state and federal policymakers, also received close attention. Nearly 200 participants attended, including state environment and energy officials, top advisers to regional climate initiatives, Congressional staff, business leaders, and experts from nonprofit organizations, among others.

As part of its Climate Change 101 series, the Pew Center released two new briefs: Cap and Trade 101 and Adaptation 101 at the event. A new paper addressing state options for a low-carbon coal policy, part of the Pew Center’s Coal Initiative Series, was also announced. A forthcoming paper by World Resources Institute Senior Fellow Franz Litz, Toward a Constructive Dialogue on Federal and State Roles in U.S. Climate Change Policy, was released for public review.

Eileen Claussen Remarks at Pew Center State-Federal Workshop

Speech by Eileen Claussen, President, Pew Center on Global Climate Change
Pew Center State and Federal Workshop

February 25, 2008

On behalf of the Pew Center on Global Climate Change and the Pew Center on the States, I’d like to welcome you to our conference: Innovative Approaches to Climate Change: A State-Federal Workshop.  I welcome the opportunity to be with all of you and kick-off this very timely conference that will examine the specific roles of Washington and the states in addressing the urgent challenge of global climate change. 

As most of you know, what is happening on this issue right now is this: In the absence of federal action, states have taken the lead in designing regulatory approaches to reduce the greenhouse gas emissions that cause climate change.   And while it is good that the states are acting - it does not mean the federal government is irrelevant. In fact, both Washington and the states have specific and important roles to play.  And I will spend a few minutes this morning discussing what these different yet complementary roles look like and mean. 

But first, let’s examine why states are acting.  I think there are three reasons:  risks, opportunities and authority.  States are very close to what is happening - they see the risks that climate change poses to their states – not just higher temperatures and heat waves, but more coastal flooding, more intense rainfall, higher levels of drought, increases in the number and intensity of wildfires, and more.  But many states also see opportunities in responding proactively to climate change, including developing new industries in alternative energy, applying information technology to buildings to improve energy efficiency, and improving the quality of life for their citizens through smarter growth. 

States also recognize that they have real authority to reduce emissions.  They are empowered to take action. States can promote clean electricity and energy efficiency with policy tools such as net metering, green pricing, and public benefit funds. States have authority to adopt building efficiency codes, which can have a major impact when you consider that energy use in buildings produces about 43 percent of U.S. carbon dioxide emissions. States also have great control over smart growth policies and transportation policies aimed at reducing emissions from cars and trucks.  These are examples of things that fall within a state’s authority and in many instances, outside the authority of the federal government. 

But what about the federal government?  Washington most assuredly has been absent from the effort to reduce U.S. emissions, as I have said.  But there are signs this will change, probably in the next couple of years.  And so, when the federal government finally chooses to act, is there a risk that it might come in and supercede all the good and thoughtful work of the states?

I think not.  I think the question of federal vs. state action on climate change is not a question of either/or.  My thesis is that the states can do some things (indeed they are better suited to do some things) and Washington can do other things that only Washington can do. And I think there is more than enough responsibility and hard work to go around.

For example, certain actions, if they are taken nationally, can be more cost-effective. And we also have to keep in mind that there is no guarantee that all states would act individually. In order to reduce emissions of greenhouse gases, and to do so both cost-effectively and to the levels scientists say are necessary, I do believe we need the federal government to step up to the plate at the same time that the states are doing their part.

One of the things that Washington can and should do is to create a national cap-and-trade program to reduce greenhouse gas emissions.  Cap-and-trade has been embraced by business and political leaders from both parties as the best and most cost-effective way to achieve real, specified reductions in emissions.  But cap-and-trade works best when it covers many emission sources. 

The more states, or the more countries, that are part of the system, the more you can achieve efficiencies of scale and the more you can lower the cost of reducing emissions.   This is why many states are reaching across their borders to establish regional cap-and-trade programs.  They understand that the economics of cap-and-trade get better when more states and more communities are involved.  But if regional approaches are better than going state-by-state, it is also true that a national approach is better than doing this on a region-by-region basis.

Ultimately, we need a national cap-and-trade program like the one making its way through the U.S. Senate. This plan aims to reduce emissions across the country and levels the playing field for businesses in all 50 states. It ensures that we’re able to take full advantage (as a nation) of the cheapest emission reductions we can find. 
Another thing that only the federal government can do is negotiate and enter into international agreements on climate change. At the federal level, the United States needs to commit to play an active part in crafting an effective global response to this problem.  We have not been playing a constructive role in this process – and that has to stop.

International negotiators, including the U.S., have agreed to a process aimed at producing a new global climate treaty by the end of 2009. This is an extremely ambitious goal, but one worth pursuing. Clearly, we need a global agreement as soon as possible that includes binding commitments from the world's largest economies.  And a global agreement that creates a worldwide market for emission reductions will help lower the global costs of achieving our emission reduction goals.    

Negotiating such an agreement is clearly a federal government responsibility … and it is a responsibility we will carry out more effectively if we commit as soon as possible to a national program of reducing emissions.  Right now, emerging economies and major sources of emissions like China and India are hiding behind U.S. inaction on this issue. U.S. leadership, in the form of mandatory emission limits at home coupled with a strong push for binding international commitments, would set the stage for effective global action – and, ultimately, real progress in reducing emissions around the world. 

Does this mean the states should step aside and cede the leadership role on the climate issue to Washington?  No. The states can and should keep exploring ways to leverage their unique authorities in areas from energy regulation to building codes, smart-growth planning and more.  States are doing important and valuable work in all of these areas, and that must continue at the same time that the federal government begins to fulfill its role in the partnership.

In closing, I want to remind you of the vision of Justice Louis Brandeis.  He saw the U.S. states as “laboratories of democracy” where policy innovations could take hold and perhaps provide models for other states, and for our national government as well.

And I honestly believe we would not be where we are today in the climate debate – on the verge of adopting a national cap-and-trade program – if many of the states had not acted first to adopt their own targets and to pursue cross-border emission trading regimes.  

The U.S. states are acting in the best traditions of federalism by advancing an array of solutions to climate change that address their specific concerns and that take advantage of their unique responsibilities in our federalist system of government.  Today, the challenge is to create a more balanced state and federal partnership – a partnership that promises to bring much-needed certainty to the question of how we as a nation are going to address the most critical environmental issue of our time.

Innovative Approaches to Climate Change: A State and Federal Workshop

Promoted in Energy Efficiency section: 
The Pew Center on Global Climate Change, in collaboration with the Pew Center on the States, hosted a two-day workshop focused on state and federal action in response to climate change.

On February 25 and 26, 2008, the Pew Center on Global Climate Change, in collaboration with the Pew Center on the States, hosted a workshop focused on state and federal action in response to climate change. The event brought together legislative staff and officials from both the state and federal levels to share their experience developing climate policies, and to discuss the appropriate roles of each level of government in implementing future national policy. Participants explored how federal policy might be informed by, and interact with, existing state efforts.

Two new publications were released at the workshop as part of the Pew Center on Global Climate Change Climate Change 101 Series:

NEW: Climate Change 101: Adaptation (Updated - January 2009)
NEW: Climate Change 101: Cap-and-Trade (Updated - January 2009)

In addition, a new publication in the Pew Center's Coal Initiative Series was also released:

NEW: State Options for Low-Carbon Coal Policy

Based in part on the results of this workshop, the Pew Center released a new report in June 2008:

About U.S. States & Regions

States and regions across the country are adopting climate and clean energy policies. These actions include the development of regional greenhouse gas reduction markets, the creation of state and local climate action and adaptation plans, and increasing renewable energy generation. In addition to addressing climate change, states and regions pursue these policies to reduce their vulnerability to energy price spikes, promote state economic development, and improve local air quality. State and regional climate policy will provide models for future national efforts, achieve greenhouse gas emissions reductions, and prepare for the impacts of climate change.

The State Solutions program at the Center for Climate and Energy Solutions conducts research and disseminates information about state actions in an effort to bring effective state climate and clean energy solutions into the federal policy-making arena and facilitate cross-fertilization between state and federal policy makers. The program provides information to states on climate impacts and policy opportunities, fosters peer-to-peer learning among state officials, and advises on the development of state and regional initiatives by providing expert advice and detailed analysis. The State Solutions group has been intimately involved in the development and implementation of every state and regional initiative that deals with cap and trade design, and many other significant state and regional policies. These efforts have included serving as advisors on policy design for the Regional Greenhouse Gas Initiative in the Northeastern U.S.; deep engagement with major initiatives in California and other Western states; and efforts in Florida, North Carolina, and several Midwestern states. Through its engagement with these state efforts, the Solutions program assists and draws lessons from their design questions and decisions.
