On June 12, 2025, President Donald Trump signed a Congressional Review Act resolution aimed at ending an Environmental Protection Agency waiver, which allowed California to set strict rules on the sale of gasoline vehicles. California’s Advanced Clean Cars II regulations are aimed at lowering emissions to protect air quality by phasing out combustion vehicles by 2035. The goal included a 35% phase-out target by 2026, 51% by 2028, and 68% by 2030, rather than a hard cut-off in 2035.
