Supreme Court limits EPA's authority to regulate power plants' greenhouse gas emissions

Washington — The Supreme Court on Thursday limited the power of the Environmental Protection Agency to regulate greenhouse gas emissions from power plants, delivering a significant blow to the Biden administration's efforts to fight climate change.

The court divided 6-3 along ideological lines in finding that Congress did not grant the EPA the authority under a provision of the Clean Air Act to devise emissions caps. Chief Justice John Roberts wrote the majority opinion, while the court's three-member liberal bloc dissented.

The decision is a victory for a group of Republican-led states and coal companies in their yearslong bid to curtail the EPA's power to issue regulations intended to curb carbon emissions.
