Power plants top source of greenhouse gases in U.S.

WASHINGTON – 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 industrial 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 15 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.
