Overview

• The U.S. Senate voted 51–44 to block California’s mandate banning the sale of new gas-powered cars by 2035, with some Democrats joining Republicans.
• The resolution now awaits President Donald Trump’s signature, alongside two additional measures targeting California’s truck emissions rules.
• California officials argue that Congress’s use of the Congressional Review Act to revoke EPA waivers is unprecedented and likely illegal, setting the stage for litigation.
• California’s mandate, adopted by 11 other states and D.C., aims for 35% of 2026 car sales to be zero-emission, rising to 100% by 2035.
• Critics of the mandate cite high costs and consumer choice concerns, while proponents emphasize its importance for public health and climate goals.
