The Obama Administration-backed 2009 Wasman-Markey House Draft and the America’s Climate Security Act of 2008 (2008 Senate Bill) proposes an 83 percent reduction in GHG emissions from 2005 to 2050 (the equivalent of 69 percent from 1990 levels), covering approximately 87 percent of potential GHG emission sources.
This goal is consistent with the EU goal of a 60-80 percent reduction from 1990 levels, existing state goals (~50-80 percent below either 1990, 2000 or 2005 levels), and the United Nation’s climate change panel’s estimate of a 50-85 percent reduction from 2000 levels.
Congress is likely to adopt an overall numerical GHG emissions reduction goal consistent with the EU goals and the scientific consensus, but tempered by the political tradeoffs needed to obtain the support of 60 Senators (e.g., the concerns of Senators from coal-producing states, the economy, uncertain compliance costs, and support from environmental advocates).
