The Trump Administration is planning a proposal that would seize control away from California regulators and prevent them from enforcing the state’s own emissions standards.

The planned proposal, revealed in a report by Bloomberg, aims to revise standards that are among the strictest in the country. The revision would also impact California’s mandate on electric vehicle sales in the state.
