"Congressional interest in climate change legislation has grown in recent years. In the 110th Congress, Members have introduced multiple bills that directly address various aspects of climate change. These bills cover a wide spectrum, ranging from climate change research to comprehensive greenhouse gas (GHG) emissions cap-and-trade programs. Additional bills focus on GHG reporting or registration, or on power plant emissions of carbon dioxide (CO2) as part of wider controls on pollutant emissions. 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; emissions reduction technologies; U.S. actions pursuant to international emission reduction agreements; adaptation to the effects of climate change; GHG reporting and registration; and GHG emissions reduction programs."
