Greenhouse Gas Reduction: Cap-and-Trade Bills in the 110th Congress
This report discusses the Cap-and-Trade Bills in the 110th Congress which are meant to advance market-based greenhouse gas reduction programs, similar to the 1990 Clean Air Act Amendments. The report presents a side-by-side comparison of the major provision in each of the bills and includes a glossary of common terms.
Costs and Benefits of Clear Skies: EPA's Analysis of Multi-Pollutant Clean Air Bills
This report examines EPA's analysis and adjusts some of its assumptions to reflect current regulations. The most important adjustment is the choice of baseline. The agency’s analysis assumes as a baseline that, in the absence of new federal legislation, EPA and the states will take no additional action to control SO2, NOx, Hg, or CO2 emissions beyond those actions finalized by mid-2004. This baseline is put forth despite three rules recently promulgated by EPA that limit SO2, NOx, and Hg emissions on a timeframe similar to that proposed by the Clear Skies legislation.
Clean Air and New Source Review: Defining Routine Maintenance
The Environmental Protection Agency (EPA) final rule on clarifying the definition of routine maintenance under its New Source Review (NSR) process exempts industrial facilities from undergoing NSR if they are replacing safety, reliability, and efficiency rated components with new, functionally equivalent equipment and if the cost of the replacement components is under 20 percent of the replacement value of the process unit.
Market-Based Greenhouse Gas Control: Selected Proposals in the 111th Congress
This report discusses several legislative proposals that would control greenhouse gas (GHG) emissions. The proposals offered to date would employ market-based approaches--either a cap-and-trade or carbon tax system, or some combination thereof--to reduce GHG emissions.
Cars, Trucks, and Climate: EPA Regulation of Greenhouse Gases from Mobile Sources
As Congress and the Administration considered new legislation to reduce the greenhouse gas (GHG) emissions that contribute to climate change over the last year and a half (a process that has now stalled), the Environmental Protection Agency simultaneously began to exercise its existing authority under the Clean Air Act to set standards for GHG emissions. The Administration has made clear that its preference would be for Congress to address the climate issue through new legislation. Nevertheless, it is moving forward on several fronts to define how the Clean Air Act will be used and to promulgate regulations. This report covers the steps that the Administration is taking on this topic.
Carbon Capture and Sequestration (CCS)
This report discusses carbon capture and sequestration (CCS), but not other types of carbon sequestration activities whereby CO2 is removed from the atmosphere and stored in vegetation, soils, or oceans.
Climate Change: Potential Regulation of Stationary Greenhouse Gas Sources Under the Clean Air Act
This report discusses the EPA's authority to control greenhouse gas (GHG) emissions from stationary sources under the Clean Air Act, and the various options that EPA could exercise.
Federal Agency Actions Following the Supreme Court's Climate Change Decision: A Chronology
This report presents a chronology of major federal agency actions taken in the wake of Massachusetts v. EPA. In Massachusetts v. EPA, the Court held that greenhouse gases (GHGs), widely viewed as contributing to climate change, constitute "air pollutants" as that phrase is used in the Clean Air Act (CAA). As a result, said the Court, the U.S. Environmental Protection Agency (EPA) had improperly denied a petition seeking CAA regulation of GHGs from new motor vehicles by saying the agency lacked authority over such emissions.
Aviation and Climate Change
This report provides background on aviation emissions and the factors affecting them; it discusses the tools available to control emissions, including existing authority under the Clean Air Act and proposed economy-wide cap-and-trade legislation; and it examines international regulatory developments that may affect U.S. commercial airlines.

Air Quality Issues and Animal Agriculture: EPA’s Air Compliance Agreement
This report discusses a plan announced by EPA in January 2005, called the Air Compliance Agreement, that would produce air quality monitoring data on animal agriculture emissions from a small number of farms, while at the same time protecting all participants (including farms where no monitoring takes place) through a “safe harbor” from liability under certain provisions of federal environmental laws.
Air Quality Issues and Animal Agriculture: EPA’s Air Compliance Agreement
From an environmental quality standpoint, much of the interest in animal agriculture has focused on impacts on water resources, because animal waste, if not properly managed, can harm water quality through surface runoff, direct discharges, spills, and leaching into soil and groundwater. A more recent issue is the contribution of emissions from animal feeding operations (AFO), enterprises where animals are raised in confinement, to air pollution. AFOs can affect air quality through emissions of gases such as ammonia and hydrogen sulfide, particulate matter, volatile organic compounds, hazardous air pollutants, and odor. These pollutants and compounds have a number of environmental and human health effects. This report reviews key issues associated with the Air Compliance Agreement.

Air Quality Standards: The Decisionmaking Process
The decisions by the Administrator of the Environmental Protection Agency (EPA) in 1997 to revise the National Ambient Air Quality Standards (NAAQS) for ozone and particulate matter refocused attention on the criteria and the process by which these decisions are made Tracing the steps of the decision pieces, this report identifies the statutory criteria established by the Congress and summarizes the administrative procedures the Agency follows in setting these standards and in reviewing them every 5 years.
Climate Change Legislation in the 109th Congress
Climate change and greenhouse gas (GHG) emissions are a continuing issue in the 109th Congress. Bills directly addressing climate change issues range from those focused primarily on climate change research to comprehensive emissions cap-and-trade programs. Additional bills focus on GHG reporting and registries, or on power plant emissions of carbon dioxide, as part of wider controls on pollutant emissions. The bills vary in their approaches to climate change issues. This report briefly discusses the basic concepts on which these bills are based and compares major provisions of the bills in each of the following categories: climate change research, technology deployment, GHG reporting and registries, and emissions reduction programs.

Estimates of Carbon Mitigation Potential from Agricultural and Forestry Activities
The report is organized into three parts. The first provides a brief overview of the role of the agriculture and forestry sectors within the broader climate change debate, describing available estimates of current GHG emissions and carbon sequestration in the farm and forestry sectors. The second describes available data and information on the potential for carbon storage (tonnage) by type of farming and forestry activity, and presents available estimates of the carbon sequestration potential in these sectors. The final part discusses some of the limitations of available estimates of GHG mitigation potential in the agriculture and forestry sectors, focusing on recent policy and market changes and other types of modeling uncertainties that could limit the accuracy of available mitigation projections.
