The Environmental Protection Agency will debut draft regulations on Monday to cut carbon emissions from power plants 30 percent from 2005 levels by 2030, according to multiple sources briefed on the proposal.
The Wall Street Journal first reported details of the climate rule on Sunday, saying that EPA will seek a 25 percent overall carbon cut by 2020. It will ratchet that requirement up to 30 percent by 2030.
Another source cautioned, however, that the 30 percent reduction may be one of several targets proposed by the EPA.
The agency plans to set varying reduction targets by state. And states will be able to chose from a menu of options to comply. This includes adding renewable-power generation to the grid, spurring energy-efficiency gains, and implementing market-based approaches, such as cap-and-trade, to rein in emissions.
The rules ares expected to be finalized by June 2015, and states will have until June 2016 to submit plans for achieving the standard.
The regulations stand as the centerpiece of the administration's effort to address global warming. Once finalized, they will help shore up the president's legacy on climate change. The White House also hopes the rules will pave the way for the U.S. to extract substantial commitments from nations such as China and India to reduce carbon emissions.
