Major automakers, represented by the Alliance for Automotive Innovation, are urging Congress to block California’s plan to phase out gasoline-only vehicles by 2035—a policy adopted by 11 other states and covering about 40% of the U.S. auto market—arguing it could soon impact vehicle shipments and consumer choice.

They warn the mandate to significantly boost electric vehicle (EV) sales, with a 35% zero-emission requirement by 2026, is unrealistic under current conditions.

The House plans to vote on repealing a waiver granted by the EPA allowing California to set its own EV and emissions standards, although the Government Accountability Office has stated the waiver cannot be overturned using the Congressional Review Act.

Automakers claim the rules will drive up prices and limit options, while California argues the measures are essential for cutting greenhouse gases and pollution.
