WASHINGTON (AP) -- President Barack Obama is planning a major push using executive powers to tackle the pollution blamed for global warming in an effort to make good on promises he made at the start of his second term.
Obama's energy and climate adviser, Heather Zichal, said Wednesday the plan would boost energy efficiency of appliances and buildings, expand renewable energy and use the Environmental Protection Agency's authority under the Clean Air Act to regulate heat-trapping pollution from coal-fired power plants.
The plan is expected to be unveiled in coming weeks.
The Obama administration has been under increasing pressure from environmental groups and lawmakers from states harmed by Superstorm Sandy to cut pollution existing power plants, the largest source of climate-altering pollution. Obama has already proposed controls on new power plants' greenhouse gases.
