The most comprehensive analysis to date on U.S. power plant air pollution emissions shows that most of the nation’s largest electric utilities have seen significant reductions in global warming pollution in recent years. The report’s release comes as the Environmental Protection Agency (EPA) prepares to finalize the Clean Power Plan to further reduce that pollution. The new report, which examines carbon dioxide (CO2), nitrogen oxides (NOx), sulfur dioxide (SO2), and mercury emissions from the nation’s 100 largest electric power producers, found that CO2 emissions from power plants decreased 12 percent from 2008 through 2013, and that the economy has continued to grow even as CO2 emissions have declined.
