On October 30, the Environmental Protection Agency (EPA) published the Final Mandatory Reporting of Greenhouse Gases Rule requiring that large sources and suppliers in the U.S. emitting more than 25,000 tons of greenhouse gases (GHGs)* per year monitor and report their emissions to the EPA on an annual basis.  The rule applies to all sectors of the economy and will be effective starting on December 29, 2009.

According to EPA’s website, this “new reporting system will provide a better understanding of where GHGs are coming from and will guide development of the best possible policies and programs to reduce emissions.”  This move to collect and analyze nationwide emissions data is the EPA’s most recent attempt to address climate change.

Facilities that currently emit more than 25,000 tons of GHG emissions per year must begin collecting data on January 1, 2010.  The first annual report of 2010 emissions is due March 31, 2011.   Participating facilities must continue to submit GHG reports every year. A facility is able to stop reporting once their GHG emissions are less than 25,000 tons per year for 5 consecutive years, or less than 15,000 tons per year for 3 consecutive years.

*The gases covered by the proposed rule are carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride, and other fluorinated gases including nitrogen trifluoride and hydrofluorinated ethers.
