The Environmental Protection Agency yesterday posted greenhouse gas emissions data for 2011 on its website, providing public access to emissions data by sector, by greenhouse gas, and by geographic region such as county or state.

Power plants accounted for 67 percent of reported emissions in 2011, with 1,594 facilities emitting a total of 2,221 million metric tons of carbon dioxide equivalent (CO2e). In 2011, emissions from power plants were approximately 4.6 percent below 2010 emissions, reflecting an ongoing increase in power generation from natural gas and renewable sources, EPA said. 

Petroleum and natural gas systems were the second largest sector, with emissions of 225 million metric tons of CO2e in 2011.

Overall, approximately 8,000 facilities in nine industry sectors reported 3.3 billion tons of carbon dioxide equivalent of direct emissions, EPA said. The agency estimates that actual emissions in the United States in 2011—as opposed to reported emissions—were 6,822 million metric tons of carbon dioxide equivalent.

The 2011 data has information from facilities in 41 source categories that emit large quantities of greenhouse gases, with new data from 12 additional source categories, including petroleum and natural gas systems and coal mines. The Greenhouse Gas Reporting Program now includes approximately 85-90 percent of total U.S. greenhouse gas emissions with the addition of the 12 new source categories in 2011, EPA said.

"With this second data release, communities, businesses and others can track and compare facilities' greenhouse gas emissions and identify opportunities to cut pollution, minimize wasted energy, and save money," said Gina McCarthy, assistant administrator for EPA’s Office of Air and Radiation. EPA’s online Facility Level Information on GreenHouse gases Tool (FLIGHT)allows users to locate large emitters in their communities or state, and to view emissions by industry type or greenhouse gas. More information on the Greenhouse Gas Reporting Program is available on EPA’s website.
