California Air Resources Board

The California Air Resources Board (CARB) invites interested parties to submit comments on potential updates to the Advanced Clean Cars regulations. Staff will present initial topics at a public workshop on November 15. The presentation materials will be available after the workshop on the Advanced Clean Cars website. The presentation covers concepts for regulatory updates to CARB’s low-emission vehicle (LEV) greenhouse gas (GHG) emission standards for model years beyond 2025; coordination between California’s LEV IV and the proposed federal Tier 4 program for light- and medium-duty vehicle criteria air pollutant requirements; and emerging topics and implementation updates related to CARB’s zero-emission vehicle (ZEV) regulation. Staff will consider comments received at the workshop and on this comment docket in further developing regulatory proposals to be presented at future workshops and outreach events. This docket will open for public comment on November 15, 2023.
