Pursuant to a congressional mandate in the 2007 Consolidated Appropriations Act, the United States Environmental Protection Agency (EPA) finalized rules establishing mandatory reporting requirements for greenhouse gas (GHG) emissions in 2009. Originally, facilities subject to the reporting rules were required to begin collecting emissions data in 2010, with the first annual report due on March 1, 2011. Recently, however, the EPA extended the reporting deadline to September 31, 2011 because its computer system proved unable to handle all of the reports by the March deadline.
