- The Carbon Cycle: Implications for Climate Change and Congress
- This report puts the human contribution of carbon to the atmosphere into the larger context of the global carbon cycle. The report focuses almost entirely on carbon dioxide (CO2), which alone is responsible for over half of the change in Earth's radiation balance. Moreover, according to the Intergovernmental Panel on Climate Change (IPCC), CO2 is the most important greenhouse gas released to the atmosphere from human activities.
- Clean Air Permitting: Status of Implementation and Issues
- This report describes the statutory background of the Title V program and the status of implementation, in terms of federal approval of state and local permitting authorities and permit issuance. It also discusses broad policy issues identified by various stakeholders, including program complexity and costs, and inconsistencies due to a lack of sufficient federal guidance.
- Air Quality: EPA's 2006 Changes to the Particulate Matter (PM) Standard
- On October 17, 2006,3 the EPA published its revisions to the National Ambient Air Quality Standards (NAAQS) for particulates to provide protection against potential health effects associated with short- and long-term exposure to particulate matter (including chronic respiratory disease and premature mortality). In order to better understand EPA's actions, this report provides an analysis of the agency's final 2006 revisions to the particulates NAAQS, and the estimated costs and benefits of the new standards and of more stringent alternatives analyzed.
- Air Quality Standards and Sound Science: What Role for CASAC?
- This report discusses the National Ambient Air Quality Standards (NAAQS), which are standards that define what EPA considers to be clean air. Their importance stems from the long and complicated implementation process that is set in motion by their establishment.
- Exemptions from Environmental Law for the Department of Defense
- Whether broader expansions from federal environmental laws are needed to preserve military readiness has been an issue. Questions have been raised as to whether environmental requirements have limited military training activities to the point that readiness would be compromised. The potential impacts of broader exemptions on environmental quality have raised additional questions. Although certain exemptions the Department of Defense (DOD) first requested in FY2003 have been enacted into law, Congress has opposed others. From FY2003 to FY2008, DOD requested exemptions from the Clean Air Act, Solid Waste Disposal Act, and Comprehensive Environmental Response, Compensation, and Liability Act. To date, Congress has not enacted these three latter exceptions. The Administration's FY2009 defense authorization bill does not include these exemptions.

- Federal Pollution Control Laws: How Are They Enforced?
- This report provides an overview of the statutory framework, key players, infrastructure, resources, tools, and operations associated with enforcement and compliance of the major pollution control laws and regulations administered by EPA. It also outlines the roles of federal (including regional offices) and state regulators, as well as the regulated community.
- Global Climate Change and Wildlife
- Recently projected climate changes could have widespread effects on wildlife species. These effects might be positive or negative, depending on the species. Some effects might include extinction, range shifts, mismatches in phenology (timing of pollination, flowering, etc.), and population changes. If the effects of climate change are widespread, there is uncertainty on how wildlife will adapt. Some suggest that evolution and migration will enable species to adapt, whereas others contend that adaptation will be minimal because of limited habitat, and changes in climate that may occur may rapidly than adaptation can respond.
- Climate Change: Design Approaches for a Greenhouse Gas Reduction Program
- This report explores strategies to control greenhouse gas (GHG) emissions and options to address the cost issue in four parts. First, the basic economic tradeoff between controlling the quantity of GHG emissions and the program's compliance costs is introduced and explained. Second, the five dimensions of the cost issue that have arisen so far in the climate change debate are identified and discussed. Third, a representative sample of proposed approaches to address cost concerns is compared and analyzed according to the five cost dimensions identified previously. Finally, the proposed options are summarized and opportunities to combine or merge different approaches are analyzed.

- Global Climate Change: Status of Negotiations
- In December 2007, the parties to the United Nations Framework Convention on Climate Change (UNFCCC) held their 13th annual meeting in Bali, Indonesia, and began the process of working toward an agreement/treaty that would succeed the Kyoto Protocol to the UNFCCC when it expires in 2012. The Protocol includes a mandate for a reduction of greenhouse gas (GHG) emissions by 30 developed/industrialized nations to an average of some 5% below their 1990 levels over the commitment period 2008-2012. The broad array of these issues, briefly discussed in this report, has been described by some as comprising perhaps the most complex negotiations ever undertaken internationally.

- Measuring and Monitoring Carbon in the Agricultural and Forestry Sectors
- Proposals to reduce emissions of carbon dioxide and other greenhouse gases often include the use of forestry and agricultural practices and lands for carbon sequestration. However, uncertainty about the accuracy of measuring carbon from these activities has led some to question this potential. Basic approaches for measuring forest and agricultural carbon include on-site measurement; indirect measurement from off-site tools; and estimation using models or inferences. Because of challenges associated with balancing the cost and accuracy of these measurement tools, any practicable system for measuring forest and agricultural carbon might require a mix of these approaches.
- Are Carbon Dioxide Emissions Rising More Rapidly Than Expected?
- This report discusses the recent emissions estimates with the greenhouse gas (GHG) and addresses the question, are carbon dioxide emissions rising more rapidly than expected?
- Are Carbon Dioxide Emissions Rising More Rapidly Than Expected?
- At least one recent report and numerous news articles suggest that carbon dioxide (CO2) emissions are rising more rapidly than expected. While CO2 emissions associated with human activities continue to rise -- and may be worthy of alarm because of their influence on climate change -- any short-term comparisons between actual emissions and the Intergovernmental Panel on Climate Change (IPCC) scenarios miss the mark. This report analyzes this issue and the issues associated with IPCC scenarios and trajectories. It also describes the importance of monitoring CO2 emissions and analyzing the factors and forces behind increasing CO2 emissions.
- The World Bank's Clean Technology Fund (CTF)
- The United States Treasury has led efforts to create a $10 billion Clean Technology Fund (CTF), located at the World Bank, to help fund deployment of clean technology to reduce greenhouse gas emissions in developing economies. The Bush administration has asked Congress to authorize and appropriate U.S. funding of $2 billion over three years (FY2009 to FY2011). While many Members of Congress have expressed support for the CTF, others have raised concerns, primarily with respect to whether the CTF should finance carbon-based energy projects. To date, Congress has not passed legislation authorizing or appropriating U.S. contributions to the Fund.
- Global Climate Change: Three Policy Perspectives
- The 1992 U.N. Framework Convention on Climate Change requires that signatories, including the United States, establish policies for constraining future emission levels of greenhouse gases, including carbon dioxide (CO2). The George H. W. Bush, Clinton, and George W. Bush Administrations each drafted action plans in response to requirements of the convention. These plans have raised significant controversy and debate. This report examines three starting points from which a U.S. response to the convention is being framed.
