Environmental Protection Agency (EPA) Mandatory Reporting Rule

Administrator: U.S. Environmental Protection Agency (EPA)


Large emitters of heat-trapping emissions were required by the Environmental Protection Agency (EPA) to begin collecting greenhouse gas (GHG) data under a national reporting system starting January 1, 2010. The reporting covers approximately 85 percent of the nation’s greenhouse gas (GHG) emissions and 10,000 facilities.


Environmental Protection Agency’s (EPA) new reporting system provides a better understanding of the sources of greenhouse gases (GHGs) and will guide development of policies and programs to reduce emissions. The data also gives businesses the ability to track their own emissions, compare them to similar facilities, and identify cost effective ways to reduce emissions.
