Electricity Restructuring: The Implications for Air Quality
In the context of federal and state proposals to restructure the electric utility industry, this paper analyzes forces and policies affecting utility generation that may have consequences for emissions of air pollutants and of greenhouse gases. Key concerns are potential increases in nitrogen oxide emissions, raising questions about the effectiveness of the Clean Air Act to regulate a restructured industry, and in carbon dioxide emissions, which are not currently regulated but could be if the U.S. ratifies the Kyoto Agreement. These issues may be raised in the context of electricity restructuring legislation. For ongoing legislative activities, see CRS Issue Brief IB10006, Electricity: The Road Toward Restructuring. digital.library.unt.edu/ark:/67531/metacrs1654/
Air Quality: Multi-Pollutant Legislation
One approach being proposed to more cost-effectively achieve national air quality goals is a "multi-pollutant" strategy -- a framework based on a consistent set of emissions caps, implemented through emissions trading. This report discusses this strategy and related legislation. digital.library.unt.edu/ark:/67531/metacrs2139/

Global Climate Change: U.S. Greenhouse Gas Emissions - Status, Trends, and Projections
This report reviews U.S. emissions of greenhouse gases in the contexts both of domestic policy and of international obligations and proposals. On October 15, 1992, the United States ratified the United Nations Framework Convention on Climate Change (UNFCCC), which entered into force on March 21, 1994. This committed the United States to “national policies” to limit “its anthropogenic emissions of greenhouse gases,” with a voluntary goal of returning “emissions of carbon dioxide [CO2] and other greenhouse gases [methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6)]” at the “end of the decade” to “their 1990 levels.” digital.library.unt.edu/ark:/67531/metacrs3733/
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. digital.library.unt.edu/ark:/67531/metacrs10807/
EPA's Clean Power Plan: Highlights of the Final Rule

The topics discussed do not represent an exhaustive list of the differences from the proposed rule or the support or opposition that may be raised by various stakeholders. digital.library.unt.edu/ark:/67531/metadc770529/
Global Climate Change Treaty: Negotiations and Related Issues
This report discusses the negotiations leading the Kyoto conference of the parties. The United States and other parties to the 1992 Climate Change Convention signed at the Earth Summit in Rio de Janeiro will meet December 1-12 in Kyoto, Japan, to conclude year-long negotiations on a legally binding protocol or amendment to reduce or stabilize emissions of greenhouse gas emissions. The U.S. proposal to reduce emissions of carbon dioxide and five other greenhouse gases to 1990 levels between 2008-2012 is less ambitious than environmentalists and many other treaty Parties urge, but represents a commitment that others, including many in business, fear could damage the economy. A key aspect of the negotiations also is what should be expected of developing nations, whose current emissions of greenhouse gases are relatively small, but are expected to increase rapidly over the next decade with economic development. A sense of the Senate resolution calls for all countries to meet scheduled reductions, and would agree to U.S. participation only if harm to the domestic economy is avoided. If agreement is reached in Kyoto, Senate approval would be required for U.S. ratification, and legislation to implement commitments would also likely be necessary. digital.library.unt.edu/ark:/67531/metacrs382/
