Turning Down the Heat: Finding Solutions for Global Warming
April 22, 1999
Good morning. Thank you for inviting me to speak here in this idyllic setting, with the White River and the mountains, truly a perfect backdrop for Earth Day 1999. The subject of the program Turning Down the Heat: Finding Solutions for Global Warming is also ideal. Addressing global warming will be one of the great challenges of the 21st century, a challenge that must be met by both my generation and your generation. It is clearly a multi-year and multi-generation task - and a topic where even the best minds may have difficulty charting a sustained and effective course. But for us to begin on the path toward solutions, we should start with a modest list of needs:
First, we need to begin with a realistic assessment of where we are in addressing this issue, both nationally and internationally;
Second, we need to begin now to seriously reduce our greenhouse gas emissions;
Third, we need to chart a course for a long term response, and begin laying the groundwork for that response; and
Finally, we need to muster the will to stay the course until we are successful in meeting the challenges of global warming.
My less than optimistic view is that we are far from coming to grips with this issue, both as a nation and as a world. And we certainly have not yet shown that we have the will to stay the course. In fact, I think the best way to illustrate our situation would be to think briefly of a painting by Pieter Brueghel titled "The Fall of Icarus." As many of you know, in Greek mythology, Icarus is the son of Daedulus, an architect and inventor who developed the labyrinth. When Daedulus and Icarus were later imprisoned in the labyrinth, Daedulus created wings of wax for both himself and his son so they could escape. They managed to flee the labyrinth and flew away. But Icarus, failing to heed his father's advice, flew too close to the sun, his wings melted, and he fell into the sea and drowned. In the Brueghel painting, as Icarus falls into the sea, no one pays any attention. The ploughman continues ploughing his field, the ship does not come to the rescue. If there is a disaster, it is someone else's disaster, and does not warrant a change in course. Well, Icarus we shouldn't be; the ploughman we cannot be.
So let us begin with a realistic assessment of where we are, and then perhaps we can chart a course for change.
Where We Are
Beginning with the science, which is the basis for dealing with this issue, I believe we can simply say that sufficient scientific knowledge exists that supports taking action. The world's best scientists agree that the earth will warm somewhere between 1.5 and 6.3 degrees Fahrenheit over the next century. They also agree that that warming will have significant impacts on the world in which we live: sea level is projected to rise between 6 and 37 inches, because water expands when heated, and because some glacial ice will melt. In addition, we can expect to lose some ecosystems, stress our already depleted water supplies, see our crop production and agricultural practices change with regional consequences, and see increases in the spread of infectious disease. Extreme weather events may also increase in frequency. Most scientists also agree that rising temperatures can be attributed, at least in part, to human activity, and, absent any effort to alter that human activity, will only result in greater temperature increases over time.
But this emerging consensus of concern has not resulted in a similar consensus for action. While it is true that opinion polls in the United States and globally suggest, by a strong margin, that the public believes that global warming is a serious issue, it is still not high on either national or global agendas. And this view is confirmed and strengthened in a survey of opinion leaders done recently for the Pew Center. In this research, completed in January of 1999, we found that 68 percent of opinion leaders (based on a sample drawn from the 1998 edition of Who's Who) believe that global warming represents a serious threat, and 61 percent are of the view that it is happening now. Seventy-six percent of these opinion leaders also believed that the United States should reduce emissions even in the absence of action by other countries, a conclusion that is supported across party lines. The strongest reasons for taking action include the desire to leave a legacy for future generations, and avoiding human suffering, and ecosystem loss.
In partial response to green public opinion, discussions of global climate change in Europe have been more constant and more politically charged than in the U.S.. And European governments have taken a more aggressive stand in the international negotiating process. But even in Europe, actions have not equaled words. Most EU governments continue to struggle with making significant reductions (beyond those garnered from loss of the industrial base in the former East Germany, or the phasing down of coal use in the United Kingdom), and some expect their emissions to grow substantially. In the United States, the debate is highly polarized, and the Administration and the Congress have been unable to agree on either a program to slow the growth in greenhouse gases, or on the funding needed for climate technology development.
But on neither continent (and certainly not in other parts of the world) has the public's concern been translated into public action. Consumer automobile purchases reflect low gasoline prices, and not the need to reduce carbon emissions. Green energy markets (where non-fossil energy is supplied) are beginning to grow, but consumer purchasing of green power still remains a choice of the few and not the many.
This lack of public will translates easily into a lack of political leadership. For while the Kyoto Protocol was agreed in December 1997, with an overall 5 percent reduction below 1990 levels to be achieved by 2012, government consultations on implementation of the agreement have been slow and contentious. The European Union, for example, has chosen to use these ongoing negotiations to redefine some of the basic parameters that were agreed in Kyoto, while the United States has indicated that it will not make any attempt to ratify the agreement until other agreements (that further define the Kyoto market mechanisms and that more deeply involve developing countries) are completed. The work plan agreed to in Buenos Aires in November 1998 contains over 152 separate items - an indication that not that much - or at least not enough -- was actually agreed the year before in Kyoto.
But if this picture looks bleak - with a concerned, but unmotivated public and a lack of leadership from governments - it is important to note that some shifts in behavior have actually occurred over the past year. In the United States, this shift can be seen in two ways. Most importantly, some in the private sector have begun to take significant actions to deal with their own emissions. BP Amoco, for example, has set a target to reduce its own emissions by 10% below 1990 levels by the year 2010. Shell International has a target of 10% below 1990 levels by 2002. United Technologies has committed to reduce its energy and water consumption per dollar of sales by 25% below 1997 levels by 2007. DuPont will reduce it global greenhouse gas emissions by 45% below 1991 levels by 2000. And Baxter International has reduced the global warming impact of its emissions by 81% since 1990. All 21 companies affiliated with the Pew Center on Global Climate Change are beginning to inventory their emissions and assess their opportunities for emission reductions. And while these companies are the exception rather than the norm, they do reflect a change - and a beginning.
I believe that we are also seeing a change up on Capitol Hill. At the beginning of this year, 12 Senators from across the political spectrum, including Senators Chaffee, Lieberman, Mack, Voinovich, Jeffords, Baucus, and Warner, introduced a climate change bill that would provide credit to companies that reduce their emissions when a regulatory program to control greenhouse gas emissions is enacted. Senators Murkowski, and Hagel are considering legislation that would provide incentives for technology research and development. It is also likely that we will see bills dealing with climate change introduced in the House over the next several months. So while these bills represent a wide range of views, they do indicate a change of tone and substance - the Congress recognizes that climate change is an issue that cannot be avoided and it is at the table thinking about possible solutions. And as I mentioned earlier, support for reducing greenhouse gas emissions even outside of an international agreement, is supported by opinion leaders without regard to political party.
A Short Term Plan
Addressing the climate change issue will require actions both in the short term and the long term - in the short term because without early and constant action we will not be able to address all of our long-term concerns. I would like to suggest that there are at least four items we can tackle now.
First and foremost, we should try to put in place a straightforward system to give credit to those corporations and entities that want to take early action to reduce their greenhouse gas emissions. We should not force progressive companies to make a choice, on the one hand, of investing in emission reducing technology now and risk being punished for it later, or, on the other hand, to forego investment to develop or install climate friendly technology for a decade or more. Failure to adopt a program to give credit for early action will essentially compel industry to defer action to avoid the uncertainty of how their actions will be treated by the government when more comprehensive programs are put in place.
Congress should step up to this issue and provide a legislative framework that will allow industry to undertake the emission reductions that will change our current course of emissions growth and result in a downward emissions trend. Of course I do not want to paper over some of the difficult questions that must be answered if we are to have an effective credit for early action program. How do we assure that the reductions that are credited are real and verified? How do we provide enough of an incentive for action, and yet do not over-mortgage the budget allocation for the United States in the Kyoto Protocol should it be ratified and enter into force? And how should we handle high-growth sectors, where emissions per unit of output may be significantly decreased, but where overall company-wide emissions may rise with vastly increased output? I would simply argue that these questions are all relevant for future carbon control activities, and we would do well to begin to work on the answers now.
It is also critical in the short term that we put in place programs and incentives for the development and diffusion of clean, green technologies. While it is important to take account of sectoral capital cycles, it is also important that we do not readily accept future investments in equipment that is not climate-friendly where alternatives are available. Such an effort should start now, but should not be geared to short term investments. Consider the 50 plus year lifetimes of power generation equipment, heating and cooling systems, and aircraft. Or consider the lifetime of simple refrigerators and freezers, where efficiencies have improved approximately 70 percent over the past 10 years, but where the old appliances still predominate in U.S. households.
As we move forward on a lower emissions path, and as we begin to invest in cleaner technologies, we must also focus our analytical efforts on developing sound methodologies and experimenting with new policy approaches. We should not fool ourselves into thinking that the requirements for addressing global climate change are simple, or even that we have a full understanding of those requirements. If we are to support carbon sequestration in trees and soils, obviously a sensible thing to do, we must develop accurate baselines and accounting systems. If we wish to control all greenhouse gases, we will need to significantly improve our ability to count those emissions in ways that can easily be monitored and verified. As we move toward establishing corporate baselines and conducting inventories, we need to deal with issues ranging from how to account for baseline changes as a result of mergers and acquisitions to whether to include employee travel as part of company-wide emissions reduction plans.
And the learning required does not stop with methodological issues. While we may have successfully implemented a sulfur dioxide emissions trading program in the United States, this does not mean that we have fully assessed what might be required for a greenhouse gas system with inter-gas, intra-company, inter-company and inter-country trading. In fact, one of the most interesting experiments now being conducted is the BP Amoco intra-company trading program, a multi-country, multi-facility effort that has already seen five trades completed at an average price of less than $20/ton. But more experimentation and learning is necessary if we are to launch a system for the global control of all greenhouse gases that will not only reduce emissions, but will do so in a manner that supports a growing global economy.
Long Term Needs
Of course no amount of short-term activity will be sufficient for dealing with what is clearly a long-term issue. We are, after all, dealing with greenhouse gases that accumulate over decades and stay in the atmosphere for thousands of years. So I would suggest that we also begin to focus on three longer term needs: the need to build stronger international capacity to deal with climate change; the need to build global institutions capable of handling topics ranging from Clean Development Mechanism projects to monitoring, verification and compliance activities; and the need to resolve global participation concerns in ways that balance effectiveness and equity.
Negotiating a regime for the control of greenhouse gas emissions and then implementing that regime on both international and national levels are highly complex tasks. Yet the capacity of most countries, particularly in the developing world, is limited. An international system is only as good as the national systems that support it. If enough nations do not implement policies to achieve their negotiated emission reductions, then globally we will not meet our targets. If there are doubts whether some nations' reductions and calculations are real, then trading markets will suffer and compliance on the part of other countries is at risk. Help with building this kind of national capacity is necessary if we are to lay the groundwork for international implementation, and we should begin now to engage this task.
And international implementation requires strong, credible and lean institutions. While some believe that most countries comply most of the time with most international treaties, reality requires that there are institutions that build trust among countries, that minimize free riders, and that maximize the incentives to comply. These institutions do so by developing methodologies, and providing assistance with implementation. They do so by developing clear, transparent processes rather than black boxes. And they do so by being both effective and efficient, a must in a climate control regime where we will likely see the creation of a competitive market for trade in emissions reductions.
But these national and international systems will only be useful if equitable participation in the international agreement is established. Global carbon dioxide emissions totaled about 28 billion metric tons in 1995. The United States is the largest emitter of these gases, both historically and currently. We are also very high on the scale of emissions per person. If we go back to 1950, our cumulative carbon emissions total 180 billion tons. Russia, the number 2 emitter, is 2/3 less, followed by China, Germany and Japan. To get more personal about it, our emissions amount to about 19 tons per person per year. But per capita emissions are 12 tons in Russia, 10 tons in Germany, 9 tons in Japan, 2 ½ tons in China, and less than ½ ton in Kenya.
For now, only 39 countries - albeit 39 of the higher emitting countries - are required to reduce their emissions of greenhouse gases. But just as there are wide disparities among countries in terms of responsibility for carbon emissions, so also are there wide disparities in the ability to pay for reductions, and the opportunities countries have for making reductions without reducing economic growth. Annual GDP per capita calculations using purchasing power parity vary from $460 to $26,000, the latter being more than $460 per week. In fact, the world's three richest individuals hold assets that are greater than the combined wealth of the 48 poorest countries. Developed countries are ½ as energy intense (measured in terms of energy used per unit of GDP) as developing countries, which are, in turn, ½ as energy intense as the Eastern European/Former Soviet Union countries.
Yet to find solutions to global warming, most countries will have to participate in a global regime. Finding an appropriate metric for the equitable distribution of the burden will be a most difficult task, one that has not been joined in the international negotiating process in a thoughtful and thorough manner. In fact, the United States has insisted on developing country participation - not an unreasonable position if solutions to the problem are to be found, and the developing world has insisted on the lead being taken by the developed world, also not an unreasonable position, and one that is consistent with the Framework Convention on Climate Change. What remains, and what is essential, is to come to some accommodation on what can be achieved both politically and practically to satisfy both equity and effectiveness concerns. It is not too early to begin this dialogue now.
Staying the Course
Of course, finding solutions to the climate change issue will require sustained effort over decades - on the part of governments, who must establish the rules and modify them as we learn more of the science, and as technological solutions begin to manifest themselves; on the part of industry, who must innovate, manufacture, and operate under a new paradigm where climate change will drive many decisions; and on the part of the public, who must also switch to a more climate-friendly path in their purchases and in their lifestyles. Can we muster the will to meet this challenge, and can we stay the course, knowing that it will be difficult and convoluted at times?
To stir your thinking, I would like to offer this quote from Alice in Wonderland, where Alice asks the Cheshire Cat: "Would you tell me, please, which way I ought to go from here?" "That depends a good deal on where you want to get to," said the Cat. "I don't much care where---" said Alice. "Then it doesn't matter which way you go," said the Cat. "---so long as I get somewhere," Alice added as an explanation. "Oh, you're sure to do that," said the Cat, "if only you walk long enough."
Well, we can't afford to walk long enough. We must know where we are going, and we must begin on the path to solutions. Today.
