Overview

• The Senate parliamentarian ruled that California's Clean Air Act waivers cannot be overturned using the Congressional Review Act (CRA).
• California's waivers allow the state to phase out gas-powered vehicles by 2035 and implement stricter emissions standards than federal regulations.
• Senate Republicans introduced a CRA resolution targeting the waivers despite the ruling, signaling potential efforts to bypass the parliamentarian.
• The Government Accountability Office previously determined that the waivers are administrative actions, not rules, and thus exempt from the CRA.
• Environmental groups praised the decision as a victory for clean air and climate policy, while Republicans criticized California's policies as costly and restrictive.
