Facing growing opposition from members of Congress, the Obama administration says it will gradually phase in controls on heat-trapping greenhouse gas emissions from power plants and other large sources of CO2.
Lisa Jackson, administrator of the U.S. Environmental Protection Agency (at left), said that beginning early next year the EPA will regulate CO2 emissions from roughly 400 large emitters of greenhouse gases, mainly coal-fired power plants.
Other major sources of CO2, such as refineries and large factories, will be subject to EPA regulation in late 2011, Jackson said in a letter to eight moderate Democratic senators concerned about the effects of the regulations on their states.
