Carbon emissions from electricity generation would need to decline by 39 percent by 2030 under the U.S. Environmental Protection Agency's proposed greenhouse gas reduction proposal today. The agency on average calls for a 30 percent reduction nationally. Texas would need to reduce its carbon emissions from 1,298 pounds per megawatt-hour, the rate in 2012, to 791 pounds per mw-h. EPA officials said the standards are based on the 2012 "state of the fleet" for each state's generation capacity, taking into account previous efforts to cut emissions through energy efficiency programs, renewable energy standards and other programs. According to EPA, Texas got about half its power in 2012 from natural gas, 32 percent from coal, 7.5 percent from wind and 8.9 percent from nuclear.
"It will be up to the states to define their plans ... to meet the goals," one of several senior EPA officials said on a conference call with reporters this morning. "Ultimately if a state doesn't set a plan the EPA will set one," said another EPA official. It could be a carbon tax or other system, they said, "and states will make their own choices of what makes sense for them."
