California sent a warning shot in a potential showdown with the incoming Trump administration, with the state’s clean-air regulators digging in on mandates for an ever-greater number of electric and fuel-cell cars.

The staff of California’s Air Resources Board called national efforts to promote electrification “very modest” after 2025 as it released a more than 660-page report Wednesday on the future of zero-emission vehicles, or ZEVs. If federal emissions standards are substantially changed, the state may revisit whether to keep coordinating with Washington’s policies, they said.
