On February 5, 2013, EPA released 2011 greenhouse gas (GHG) emissions data collected through the GHG Reporting Program. The data primarily is accessible through the Facility Level Information on Green House gases Tool (FLIGHT), a web-based data publication tool.
FLIGHT includes information from facilities in 41 source categories and provides GHG emissions data by sector and geographic region. According to EPA, the data shows that power plants remain the largest stationary source of GHG emissions, with 2,221 million metric tons carbon dioxide equivalent (mmtCO2e), roughly one-third of total U.S. emissions. 2011 emissions from power plants were approximately 4.6 percent below 2010 emissions.
FLIGHT is available at http://www.epa.gov/ghgreporting. The data also is available through EPA’s online database EnviroFacts, http://epa.gov/enviro, which allows a user to search for information by zip code.
