WASHINGTON – (INT) - The U.S. Supreme Court has reversed a lower court’s order dismissing a challenge to California’s 2013 Clean Air Act waiver governing the adoption of emission standards for new vehicles.

“While we are disappointed by the Supreme Court’s decision to allow this case to go forward in the lower court, we will continue to vigorously defend California’s authority under the Clean Air Act,” said California Attorney General Rob Bonta.

“Congress intended for California to be able to regulate emissions from new vehicles sold in our state, and we remain firmly committed to advancing and implementing strong standards that safeguard public health and reduce climate pollution. The fight for clean air is far from over.”
