A rule proposed by the Enivironmental Protection Agency would cut carbon pollution from power plants 30 percent from 2005 levels by 2030 – the equivalent, according to the agency, of taking two-thirds of all cars and trucks in America off the road. Here are some things to know about the rule:
• The E.P.A. expects that under the regulation, 30 percent of electricity in the United States will still come from coal by 2030, down from about 40 percent today.
• The rule is not an executive order. Under the Clean Air Act, the E.P.A. is required to regulate any substance defined as a pollutant, which the law defined as substances that endanger human life and health. A 2007 Supreme Court decision led to an E.P.A. determination that carbon dioxide is a pollutant, thus requiring that the agency regulate it or be in violation of the law.
