In its Fiscal Year 2008 Consolidated Appropriations Act, Congress called for EPA to publish a proposed greenhouse gas reporting rule by September 2008, and a final rule by June 2009 following comments. The legislation has a broad mandate that would require reporting of greenhouse gas emissions “above appropriate thresholds in all sectors of the economy.” EPA is tasked with determining the appropriate threshold levels and frequency of reporting. The overall purpose is to collect comprehensive data that may be used in future climate policy decisions, including potential regulation under the Clean Air Act.
