E.P.A. Expected to Erase Limits on Climate Pollution From Power Plants

The Trump administration plans to announce Monday that the United States will no longer limit the planet-warming pollution that power plants pump into the air while burning coal and gas, according to two people familiar with the proposal.

The shift by the Environmental Protection Agency would complete the administration's erasure of the most consequential climate policies of Presidents Joseph R. Biden Jr. and Barack Obama. If the move survives expected legal challenges, it could also prevent future administrations from regulating greenhouse gas emissions from power plants.
