"WASHINGTON — States and cities sued the Trump administration Thursday for repealing rules that limit planet-warming greenhouse gas emissions from power plants fueled by coal and natural gas.

Twenty-one states, led by New York, are challenging the Environmental Protection Agency’s power plant rule. The Democratic-led coalition also includes Pennsylvania’s governor, the District of Columbia, New York City, Chicago and the city and county of Denver. They argue that “gutting one of the country’s most significant climate protections” will set the nation back decades and worsen the climate crisis.

The EPA announced last month it’s revoking the Biden-era rule, and said it is taking a separate but related step to prevent future administrations from regulating climate pollution from power plants.

New York Attorney General Letitia James said the federal government is showing “callous disregard” for Americans’ health and the environment, and future generations will pay the price. Power plants that burn fossil fuels are a major source of planet-warming pollution."
