Supreme Court limits EPA in curbing emissions

Climate

(NewsNation) — The Supreme Court ruled the Clean Air Act does not give the Environmental Protection Agency broad authority to regulate greenhouse gas emissions from power plants that contribute to global warming.

This is a major blow in the fight against climate change and limits how the nation’s main anti-air pollution law can be used to reduce carbon dioxide emissions from power plants. The court ruled in a 6-3 vote, with the conservatives in the majority.

The court’s ruling could complicate the Biden administration’s plans to combat climate change. Its proposal to regulate power plant emissions is expected by the end of the year.

President Joe Biden aims to cut the nation’s greenhouse gas emissions in half by the end of the decade and to have an emissions-free power sector by 2035. Power plants account for roughly 30% of carbon dioxide output.

“Capping carbon dioxide emissions at a level that will force a nationwide transition away from the use of coal to generate electricity may be a sensible ‘solution to the crisis of the day,’” Chief Justice John Roberts wrote in his opinion for the court.

But Roberts wrote that the Clean Air Act doesn’t give EPA the authority to do so and that Congress must speak clearly on this subject.

“A decision of such magnitude and consequence rests with Congress itself, or an agency acting pursuant to a clear delegation from that representative body,” he wrote.

In a dissent, Justice Elena Kagan wrote that the decision strips the EPA of the power Congress gave it to respond to “the most pressing environmental challenge of our time.”

Kagan said the stakes in the case are high. She said, “The Court appoints itself—instead of Congress or the expert agency—the decisionmaker on climate policy. I cannot think of many things more frightening.”

The case, West Virginia v. EPA, came after the EPA under Democratic former President Barack Obama sought to impose a sweeping rule, requiring U.S. power plants to slash greenhouse gas emissions, mainly by shifting away from fossil fuels like coal toward cleaner energy sources like solar and wind. Two coal companies and 17 Republican-led states led by major coal producer West Virginia asked the Supreme Court to bring the case forward.

The states argued that the EPA exceeded its authority by trying to regulate carbon dioxide under the Clean Air Act and by doing so in a way that would have vast economic impacts. The American power sector is the source of about a quarter of U.S. greenhouse gas emissions, making it a big target in the fight against climate change.

The justices heard arguments in the case on the same day that a United Nations panel’s report warned that the effects of climate change are about to get much worse, likely making the world sicker, hungrier, poorer and more dangerous in the coming years.

But that plan never took effect. Acting in a lawsuit filed by West Virginia and others, the Supreme Court blocked it in 2016 by a 5-4 vote, with conservatives in the majority.

With the plan on hold, the legal fight over it continued. But after President Donald Trump took office, the EPA repealed the Obama-era plan. The agency argued that its authority to reduce carbon emissions was limited and it devised a new plan that sharply reduced the federal government’s role in the issue.

New York, 21 other mainly Democratic states, the District of Columbia and some of the nation’s largest cities sued over the Trump plan. The federal appeals court in Washington ruled against both the repeal and the new plan, and its decision left nothing in effect while the new administration drafted a new policy.

Adding to the unusual nature of the high court’s involvement, the reductions sought in the Obama plan by 2030 already have been achieved through the market-driven closure of hundreds of coal plants.

Power plant operators serving 40 million people called on the court to preserve the companies’ flexibility to reduce emissions while maintaining reliable service. Prominent businesses that include Apple, Amazon, Google, Microsoft and Tesla also backed the administration.

Nineteen mostly Republican-led states and coal companies led the fight at the Supreme Court against broad EPA authority to regulate carbon output.
