The California Air Resources Board (CARB) has released its final set of modifications to the Advanced Clean Fleets (ACF) regulation. This regulation seeks to “accelerate the widespread adoption of zero-emission vehicles (ZEV) in the medium- and heavy-duty sector and for light-duty package delivery vehicles.”

The updated draft and additional materials are available online at the CARB website. The public has only 15 days to review and comment on the extensive revisions contained in the “15-Day Notice.” The deadline for submitting comments is Friday, April 7, 2023.

CRTA continues to seek amendments to the proposed rulemaking that will enable flexibility and prioritize the use of the “cleanest available control technology,” as defined by CARB’s own stringent engine emissions standards, when zero-emission trucks are not commercially available.

Additional information is available. The CARB Board Members are scheduled to consider the approval of the final language at their April board meeting.
