California secures emissions waiver as Trump plans reversal

The Biden administration approved California's authority to enforce stricter vehicle emissions standards, just before Donald Trump takes office vowing to reverse the decision.

Alex Nieves and Debra Kahn report for POLITICO.


In short:

  • The EPA granted California permission to enforce emissions rules stricter than federal standards for cars and heavy-duty trucks.
  • Trump’s incoming administration plans to revoke these waivers, siding with the auto industry’s push for a single national standard.
  • The waiver approval gives California legal leverage, but Trump could still initiate a lengthy process to undo it.

Key quote:

“Naysayers like President-elect Trump would prefer to side with the oil industry over consumers and American automakers, but California will continue fostering new innovations in the market.”

— Gavin Newsom, governor of California

Why this matters:

California’s ability to set higher emissions standards drives national policy, as other states often follow its lead. Reversing this authority could stall efforts to curb air pollution and reduce climate change impacts, affecting public health and environmental goals.
