These regulations will spell trouble for coal-fired power plants, which currently emit more than 30% of our nation's global warming pollution.  It also paves the way for the EPA to grant a waiver allowing California and more than a dozen other states to set landmark global warming emissions limits for vehicles.

This action was set in motion by an April 2, 2007, Supreme Court decision in Massachusetts v. EPA, which found that carbon dioxide (CO2) was a pollutant under the Clean Air Act. The Court decision ordered EPA to determine whether CO2 endangered public health or welfare, and, if so, to begin regulating CO2. 

The Bush administration unlawfully ignored the decision for nearly two years, continuing its long campaign of denial, obfuscation, and foot-dragging on global warming and other key environmental issues. The information revealed today sends a clear signal to new coal plant developers that the foot-dragging is over and that they will soon be held responsible for their global warming emissions.  With carbon capture and storage technology still years away (if it's possible at all), coal plants are becoming an increasingly risky and poor investment.

Today's document leak also comes on the heels of the EPA also announcing the first comprehensive national system for reporting emissions of carbon dioxide and other greenhouse gases produced by major sources in the United States.

From the EPA news release:

"The new reporting requirements would apply to suppliers of fossil fuel and industrial chemicals, manufacturers of motor vehicles and engines, as well as large direct emitters of greenhouse gases with emissions equal to or greater than a threshold of 25,000 metric tons per year….The vast majority of small businesses would not be required to report their emissions because their emissions fall well below the threshold."

This clarification from the EPA rules out a commonly made argument from foes of carbon limits, who say any carbon requirements will hurt small businesses other small organizations with their own facilities.

It's clear that the administration understands the urgency to act on global warming and the sweet spot of solutions that can not only help our climate, but can also help our economy recover. Consistent with President Obama's economic recovery plan, today's revelations take America one step closer to a future powered by green energy and green jobs.
