Update:

The U.S. Supreme Court’s right-wing majority handed down a decision Thursday that will severely limit the Environmental Protection Agency’s authority to regulate planet-warming greenhouse gas emissions from power plants, undermining the federal government’s ability to combat the climate emergency.

In its 6-3 ruling in West Virginia v. Environmental Protection Agency, the court’s conservative justices—led by Chief Justice John Roberts—sided with the coal industry and Republican attorneys general who sought to curb the EPA’s rulemaking powers under the Clean Air Act.

Amy Coney Barrett, one of the right-wing justices who voted to limit the EPA’s authority, has family ties to the fossil fuel industry.

Liberal Justice Elena Kagan warned in her dissent that “today, the court strips the Environmental Protection Agency of the power Congress gave it to respond to ‘the most pressing environmental challenge of our time.'”

Environmentalists echoed that assessment in response to the majority’s decision, the latest in a series of hugely consequential rulings over the past week.
