This joint resolution would use Congress's power to disapprove federal regulations to overturn an Environmental Protection Agency rule that restored California's authority to set its own vehicle pollution standards and implement its Advanced Clean Car Program. The rule, which was originally issued in March 2022, allows California to enforce stricter emissions requirements than federal standards, affecting automakers and consumers in California and potentially other states that follow California's standards. The resolution has no funding provisions or implementation timeline since its sole purpose is to nullify the EPA regulation. If passed, the rule would be eliminated and have no legal effect. The resolution was introduced by a group of Republican senators and was referred to the Senate Committee on Environment and Public Works.
