States and industry groups had asked the Supreme Court to pause the EPA's rule that aims to curb emissions of methane from new and existing oil and gas facilities.

Republican-led states and industry groups argued that the Environmental Protection Agency had moved too fast and imposed onerous regulations.

The Supreme Court on Friday let stand Biden administration rules that would cut emissions of the planet-warming gas methane as well as mercury in a rare win for an environmental regulation pending before the conservative high court.
