President Donald Trump moved Thursday to eliminate California’s nation-leading vehicle emissions standards, upending strict rules that had become a template for states across the nation to realize their greenhouse gas ambitions.

In a controversial move, President Donald Trump has signed a ban on California's EV regulations, igniting diverse reactions and setting the stage for a nationwide debate on electric vehicle mandates.

Trump also revoked two other Biden-era waivers on Thursday. Those would have allowed California to require vehicle makers to produce an increasing number of zero-emission heavy-duty trucks, and to reduce nitrogen oxides, a component of smog, from heavy-duty highway and off-road vehicles and engines.
