California urges Trump administration to abandon fuel rule plan

California’s top air regulator urged the Trump administration on Sunday to abandon a plan to freeze fuel efficiency standards through 2026, as automakers urged state and federal regulators to reach agreement to extend nationwide rules. Mary Nichols, who chairs the state’s Air Resources Board, asked the U.S. National Highway Traffic Safety Administration (NHTSA) and Environmental Protection Agency to reverse course, saying the plan to freeze requirements at 2020 levels “turns its back on decades of progress in cleaning up cars and trucks.”
