With Secretary Clinton’s announcement this week of a new coalition aimed at short-lived climate pollutants such as methane and soot, the U.S. is helping to focus international attention on a critical but frequently overlooked dimension of the climate challenge. To maximize its leadership on this front, the U.S. should also take stronger steps to tackle these pollutants at home.
The new multilateral effort to address short-lived climate pollutants (also called short-lived climate forcers) is an important recognition of both the scientific and political realities that surround climate change. A growing body of scientific evidence underscores the importance of near-term action to slow the rate of climate change, which is proceeding more rapidly than scientists predicted. Because methane, black carbon and hydroflurorocarbons (HFCs) have relatively short atmospheric lifetimes, reductions in these compounds will have significant near-term benefits in reducing climate change. In contrast, carbon dioxide remains in the atmosphere for hundreds of years. Reductions in CO2 are critical to limit the amount of warming over the longer term, but have more limited impact in the near term.
Eileen Claussen Comments on the Climate and Clean Energy Coalition to Reduce Short-Lived Climate Pollution
Statement of Eileen Claussen

February 16, 2012
The Climate and Clean Energy Coalition to Reduce Short-Lived Climate Pollution offers a promising avenue for practical action to slow the pace of global warming.
Going after black carbon, methane and other short-lived climate forcers is no substitute for a strong, sustained effort to significantly reduce emissions of carbon dioxide, the main driver of climate change. Nor can this new coalition take the place of the U.N. Framework Convention on Climate Change, the principal forum for mobilizing the global climate response.
But targeted efforts to reduce short-lived climate pollution can moderate climate impacts in the near term while we work toward the longer-term strategies needed to rein in carbon dioxide emissions. They could prove especially critical in slowing the loss of sea ice and of glaciers that millions rely on for freshwater. Many of these measures would also protect public health by curbing local air pollution, particularly in developing countries.
At a time when comprehensive solutions to the climate challenge are not yet at hand, we need to tackle it piece by piece, pursuing practical strategies wherever we can. This coalition is a good example. If the countries launching it can deliver the resources, and succeed in recruiting others to the effort, this new initiative has the potential to make a real difference.

Learn more about short-lived climate forcers
There is growing recognition within the scientific and policy communities that efforts to address climate change should focus not only on substantially reducing carbon dioxide (CO2) emissions, but also on near-term actions to reduce climate-warming substances with much shorter atmospheric lifetimes. These are called short-lived climate forcers (SLCFs). This two-pronged strategy would accomplish two goals:
- Reducing CO2 emissions limits the ultimate amount of warming. Because CO2 represents by far the largest source of climate-warming emissions, and because it stays in the atmosphere for hundreds of years, large reductions in CO2 emissions are required to meet any long-term climate stabilization goal, such as the 2°C goal set by the international community.
- Reducing emissions of short-lived climate forcers would, on the other hand, slow the near-term rate of climate change. Scientists estimate that SLCFs account for 30 to 40 percent of the human-induced warming to date. Yet as SLCFs remain in the atmosphere for periods of only a few days to a few decades, their warming effect is short-lived, and reducing their emissions would result in more immediate benefits. In addition to limiting climate impacts already underway, including important regional impacts such as glacial melting, SLCF reductions would reduce local air pollution and produce other co-benefits. The U.N. Environment Programme recently estimated that aggressive efforts to reduce SLCFs would avoid 2.4 million premature deaths by 2030 and reduce warming between now and 2040 by a half a degree.
Key Short-Lived Climate Forcers
Methane has an atmospheric lifetime of about 12 years. Human-induced methane emissions result primarily from oil and gas production and distribution, coal mining, solid waste landfills, cultivation of rice and ruminant livestock, and biomass burning. Reductions in methane emissions improve local air quality by reducing ground-level ozone, which harms agriculture and human health, and is itself an SLCF.
Black carbon (BC) results from incomplete combustion of biomass and fossil fuels. Its major sources are diesel cars and trucks, cook stoves, forest fires, and agricultural open burning.
Because of a very brief atmospheric lifetime measured in weeks, black carbon's climate effects are strongly regional. BC particles give soot its black color and, like any black surface, strongly absorb sunlight. In snow-covered areas, the deposition of black carbon darkens snow and ice, increasing their absorption of sunlight and making them melt more rapidly. BC may be responsible for a significant fraction of recent warming in the rapidly changing Arctic, contributing to the acceleration of sea ice loss. BC also is contributing to the melting of Himalayan glaciers, a major source of freshwater for millions of people in Asia, and may be driving some of the recent reduction in snowpack in the U.S. Pacific Northwest.
Black carbon's short lifetime also means that its contribution to climate warming would dissipate quickly if emissions were reduced. Additionally, since BC contributes to respiratory and cardiovascular illnesses, reductions in BC emissions would have significant co-benefits for human health, particularly in developing countries.
Hydrofluorocarbons (HFCs) are a family of industrially produced chemicals widely used in refrigeration and air conditioning. They were developed to replace ozone-depleting substances a few decades ago, HFC-134a, the most widely used of these compounds, has an atmospheric lifetime of 13 years.
As many ozone-depleting substances are also potent greenhouse gases, their phase-out under the Montreal Protocol has contributed indirectly but very significantly to climate mitigation efforts to date. The treaty's net contribution to climate mitigation is estimated to be five to six times larger than the Kyoto Protocol's first commitment period targets.
Many countries now favor working through the Montreal Protocol to phase down HFCs. A proposal by the United States, Mexico and Canada would require an 85 percent reduction in specified HFCs by 2033 for developed countries, and 2043 for developing countries. A proposal by the States of Micronesia and Mauritius calls for a 90 percent reduction by developed countries by 2030, but specifies no schedule for developing countries.

Statement of Eileen Claussen

We share President Obama’s enthusiasm for homegrown solutions to America’s energy challenges. Without question, America has the resources and know-how to produce more energy at home, strengthening both our economy and our national security. But protecting the climate also has to be part of the equation. If we sensitively develop domestic reserves, get serious about ramping up new energy sources, and push efficiency across the board, we can both meet America’s energy needs and dramatically shrink our carbon footprint.
Even if comprehensive legislation remains off the table for now, we can make important progress tackling these challenges piece by piece. C2ES is working with policymakers and stakeholders on ways to expand enhanced oil recovery using captured carbon dioxide – an approach that can boost domestic oil production while reducing greenhouse gas emissions. Similarly, we’re working with automakers, environmentalists and others on a plan for integrating plug-in electric vehicles into the U.S. electrical grid. We look forward to sharing the results of these and other C2ES initiatives aimed at practical solutions to our twin climate and energy challenges.

Read the full transcript of the 2012 State of the Union Address
The Center for Climate and Energy Solutions (C2ES) was named the world’s top environmental think tank in a global survey of top public policy research institutes.
The University of Pennsylvania’s 2011 Global Go-To Think Tank Rankings are based on a survey of more than 1,500 policymakers, scholars, journalists, think-tank executives and others worldwide. The survey assessed more than 5,300 organizations nominated in 30 categories to create a global list of top think tanks by region and policy area.
C2ES’s predecessor organization, the Pew Center on Global Climate Change, was named the world’s top environmental think tank in the same survey in 2009. The center began operating as C2ES in November 2011, and is listed in the new survey under its former name.
“While our name has changed, we remain as committed as ever to fact-based analysis and common-sense solutions to our climate and energy challenges,” said C2ES President Eileen Claussen. “We are thrilled to again be recognized as the world’s top environmental think tank. I’d like to commend the C2ES staff and thank all of our partners and supporters in the United States and abroad for helping to make this possible.”
The independent, nonpartisan center provides impartial information and analysis on energy and climate challenges; convenes policymakers and stakeholders to work toward consensus solutions; works with members of its Business Environmental Leadership Council and others to promote on-the-ground action; and promotes pragmatic, effective climate and energy policies at the state, national and international levels.
The annual survey, first published in 2007, is directed by James G. McGann, assistant director of the University of Pennsylvania’s International Relations Program and director of the Think Tanks and Civil Society Program.
The World Resources Institute and Chatham House ranked second and third, respectively, among the study’s top 30 environmental groups. Brookings Institution was named the top overall think tank. Additional categories in which the report ranks organizations include health policy, international development, and security and international affairs, among others.

Australia's Carbon Pricing Mechanism
Australia’s Clean Energy Future plan is a comprehensive set of national policies aimed at reducing greenhouse gas emissions and driving investments in clean energy. At its core is a carbon pricing mechanism starting in July 2012 and covering approximately 60 percent of Australia’s emissions. The pricing mechanism begins with a fixed carbon price for the first three years, then transitions to a cap-and-trade program. Revenue generated by the carbon price will be used to ease costs for households and industry and for investment in renewable power, energy efficiency, and other low-carbon alternatives. This brief summarizes the carbon price mechanism and other key features of the Clean Energy Future plan.
On November 8, 2011, the Australian Senate gave final approval to the government’s Clean Energy Future climate change plan outlining a series of measures to reduce greenhouse gas (GHG) emissions and drive investment in clean energy. A central element of the plan is a carbon pricing mechanism directly covering 50 percent of Australia’s emissions and providing direct financial support for renewable energy, energy efficiency, reducing emissions from land-use and forestry, and other elements. The mechanism starts with a fixed price for the first three years from 2012 to 2015 (AUD 23, rising with inflation to about AUD 25 at the end of the fixed-price period). It then transitions from 2015 to 2018 to a cap-and-trade program, with a price cap and price floor. Regulations to implement the plan are being developed. Other principal elements of the plan include:
- A long-term target of reducing GHG emissions 80 percent below 2000 levels by 2050;
- Over 50 percent of revenue generated from the carbon price is returned to households, particularly low-income ones, through tax relief and greater family benefit payments;
- Revenue generated by the program, along with additional government resources, will be used to ease the impact on trade-exposed industries and workers, and boost investments in renewable power, energy efficiency and other low-carbon alternatives;
- Implementation of the plan is expected to cost the government AUD 4.3 billion over the first four years, over and above revenue generated;
- Emissions from sectors not directly covered by the carbon price, such as certain fuels and synthetic gases, are indirectly addressed through changes to existing levies and taxes;
- Politically sensitive sectors are carved out of the mechanism: agriculture is addressed separately through an incentive-based scheme, and road transport fuels are largely exempt from the carbon price;
- Three new governance institutions are established to administer, oversee, and advise on all areas of the plan.
