The Supreme Court on Wednesday allowed the Environmental Protection Agency to move ahead with its plans to limit carbon emissions by power plants, handing a victory to the Biden administration.

The decision, which was temporary, centered on a major regulation the administration enacted in April that seeks to eliminate pollution from coal, which emits more carbon dioxide than any other fossil fuel.

The move was part of the Biden administration’s promise to curb pollution from such emissions by 2050.

More than two dozen states challenged the regulation, arguing that the federal government had failed to prove that the techniques used to control emissions would curtail them to the degree that the government is seeking.

The ruling, which was provisional, was in response to an emergency application as a challenge moves through the lower courts.

The agency has repeatedly been stymied in the courts during the Biden administration over its efforts to protect the environment. In June, the Supreme Court temporarily paused an E.P.A. plan to curb air pollution that drifts across state lines. It has also constrained the agency’s ability to limit water pollution and factors that lead to climate change.
