WASHINGTON (Reuters) – The U.S. Supreme Court declined on Friday to put on hold new federal air pollution rules from President Joe Biden’s administration to tighten limits on mercury and methane, acting in challenges brought by a group of states – most of them Republican-led – and industry groups.

The justices denied emergency requests by the states, as well as power and mining, oil and gas companies, to halt the Environmental Protection Agency rules while litigation continues in lower courts.
