States and industry groups have flooded the U.S. Supreme Court’s emergency docket in recent days in an effort to block the U.S. Environmental Protection Agency’s latest rule requiring coal power plants to install carbon-capture technology.

Led by the coal-mining state of West Virginia, a group of Republican attorneys general say the EPA is trying to circumvent recent court decisions blocking earlier versions of its anti-coal agenda, including the Supreme Court’s own 2022 decision in West Virginia v. EPA. There, the court’s conservatives blocked the Biden administration’s ambitious efforts to shift the nation’s energy grid from coal via a comprehensive energy credit program.
