The U.S. Environmental Protection Agency (EPA) recently finalized a reporting rule that will require any entity that emits 25,000 tons of CO2e or more a year to collect data on its 2010 emissions and to report this information to the EPA in the first quarter of 2011. The GHGs covered include carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride and other fluorinated gases. The reporting rule is expected to apply to about 10,000 large emitters, which account for about 80% of total U.S. GHG emissions. As reported in our August 2009 Bulletin, Environment Canada already has similar reporting requirements in place, requiring any person who operates a facility that emits 50,000 tonnes or more of CO2e in the 2009 calendar year to submit information about those emissions to the federal government no later than June 1, 2010.
