U.S. EPA Releases Greenhouse Gas Reporting Rules

The U.S. Environmental Protection Agency (EPA) has issued the Final Mandatory Reporting of Greenhouse Gases (GHG) Rule which will require mandatory reporting of GHG emissions from large sources in the U.S. Beginning on January 1, 2010, manufacturers of vehicles and engines, suppliers of fossil fuels or industrial GHGs, and facilities that emit at least 25,000 metric tons of GHGs per year will be required to submit annual reports to EPA. Vehicle and engine manufacturers outside the light-duty sector will be required to report carbon dioxide emissions levels beginning with Model Year 2011 and other GHG emissions in subsequent model years. This includes heavy trucks, motorcycles, and non-road engines and equipment; requirements related to light-duty vehicles are not included in this rulemaking. The new reporting system covers approximately 85% of the nation's GHG emissions and will provide comprehensive data for analysis to help inform future policy decisions.
