President Joe Biden on Monday announced an executive action that will permanently ban future offshore oil and gas development in parts of the Atlantic and Pacific oceans in a way that could be especially difficult for the incoming Trump administration to undo.

Biden’s orders would not affect large swaths of the Gulf of Mexico, where most U.S. offshore drilling occurs, but it would protect coastlines along California and Florida.

The move would bar new oil and gas leases along the Atlantic coast, the eastern Gulf of Mexico, the Pacific coast and portions of the northern Bering Sea
