The 15 Dirtiest Power Plants In the US

On June 2, President Obama proposed new EPA regulations to reduce the carbon dioxide pollution that's causing global warming. The new rules would reduce the carbon emissions of US power plants 30 percent by 2030. But not all plants are created equal—in fact, some are much dirtier than others.

According to a 2013 report, the following 15 primarily coal-fired power plants are the top emitters of carbon dioxide in the United States. For reference, your average passenger vehicle emits five metric tons of carbon dioxide per year—and these plants are exceeding that by millions and millions.
