President Obama will use his executive authority to cut carbon emissions from the nation’s coal-fired power plants by up to 20 percent, according to people familiar with his plans, which will spur the creation of a state cap-and-trade program forcing industry to pay for the carbon pollution it creates.
Mr. Obama will unveil his plans in a new regulation, written by the Environmental Protection Agency, at the White House on Monday. It would be the strongest action ever taken by an American president to tackle climate change and could become one of the defining elements of Mr. Obama’s legacy.
