In a
letter published earlier this month, a coalition of 19 states and municipalities have
appealed to President-elect Donald Trump to protect the Clean Power Plan, a rule that "reasonably limits emissions from fossil-fueled power plants". The Plan is a signature accomplishment of the Obama administration and is projected to eliminate 870 million tons of harmful gases by 2030-- equal to the yearly emissions of about 160 million cars, and 30% of carbon pollution.
