The Environmental Protection Agency is expected to repeal rules that limit planet-warming greenhouse gas emissions from power plants fueled by coal and natural gas, an action that Administrator Lee Zeldin has said would remove billions of dollars in costs for the industry and help "unleash" American energy. The rule change, proposed last year, could be announced as soon as Monday, according to two people familiar with the proposal, and represents a fundamental shift from efforts by Democratic Presidents Joe Biden and Barack Obama to address climate change and clean up industrial pollution, often in low-income and majority Black or Hispanic communities. The rule, which is expected to face immediate legal challenges, also could prevent future administrations from regulating greenhouse gas emissions from power plants, the people familiar with the proposal said.
