Date Filed: May 23, 2024
Original Court: U.S. Court of Appeals for the D.C. Circuit
Case Status: Held in Abeyance Pending EPA’s Reconsideration
In 2024, the Biden Environmental Protection Agency issued stringent new rules governing greenhouse gas emissions from trucks and cars. Together, the two rules require that at least 30% of trucks and 70% of cars be all-electric by 2032. CAF represents the Western States Trucking Association and the Construction Industry Air Quality Coalition, two trade associations whose members are directly and adversely impacted by the new rules.
CAF attorneys argue that Congress has not granted EPA the authority to regulate greenhouse gasses nor mandate vehicle electrification. Therefore, these rules violate the Clean Air Act and the Major Questions Doctrine.
On his first day in office, President Trump issued an Executive Order requiring EPA to reevaluate any standards that favor or mandate electric vehicles, including the regulations challenged here. The court has placed this case in abeyance while EPA reevaluates these regulations.
