WASHINGTON (AP) — The most detailed data yet on emissions of heat-trapping gases show that U.S. power plants are responsible for the bulk of the pollution blamed for global warming.
Power plants released 72 percent of the greenhouse gases reported to the Environmental Protection Agency for 2010, according to information released Wednesday that was the first catalog of global warming pollution by facility. The data include more than 6,700 of the largest sources of greenhouse gases, or about 80 percent of total U.S. emissions.
According to an Associated Press analysis of the data, 20 mostly coal-fired power plants in 14 states account for the top-releasing facilities.
Gina McCarthy, the top air official at the EPA, said the database marked “a major milestone” in the agency’s work to address climate change. She said it would help industry, states and the federal government identify ways to reduce greenhouse gases.
The Obama administration plans to regulate emissions of heat-trapping gases under existing law. A proposed regulation to address pollution from new power plants could be released as early as this month. Eventually, the EPA will have to tackle facilities already in operation. The largest emitters will be the first in line.
The largest greenhouse gas polluter in the nation in 2010, according to the EPA’s data, was the Scherer power plant in Juliette, Ga., owned by Southern Company. That coal-fired power plant reported releasing nearly 23 million metric tons of carbon dioxide, the chief greenhouse gas, in 2010.
Two other power plants owned by Southern were the second- and third-largest polluters nationally: the Bowen plant in Bowen, Ga., and the James H. Miller, Jr. power plant in Quinton, Ala.
American Electric Power, another large coal-fired power producer, has three power plants in the top 20. They are in Rockport, Ind., Cheshire, Ohio, and St. Albans, W. Va.
“This is just another way to identify the largest coal-fired power plants in the country,” said AEP spokesman Pat Hemlepp. “We always assumed we would be No. 1 in greenhouse gas emissions or No. 2 behind Southern Co. Us and Southern are the two largest consumers of coal.”
The other states with high-polluting power plants are Texas, Michigan, Missouri, Montana, Pennsylvania, Arizona, Wyoming, North Carolina and Kansas.
Refineries were the second-largest source of greenhouse gas emissions, with 5.7 percent of the reported total. The top states in greenhouse gas emissions from power plants and from refineries were Texas, Pennsylvania, Florida, Ohio, and Indiana.
Congress required industries to report their emissions as part of a 2008 spending bill. Until now, the agency has estimated greenhouse gas emissions by industry sector.
