CARB Truck Partnership Under Attack…and Rightfully So!

August 20, 2025/in Regulations & CARB

The following is a chronology of several recent actions and related attachments with additional details concerning the CARB Clean Truck Partnership (CTP)…arguably a preempted, underground agreement. The following are recent events related to this scheme.

On August 7, the US Department of Justice (DOJ) issued a cease-and-desist order to Daimler to order them to abandon CARB combustion engine regulatory standards in light of the Congressional Review Act (CRA), 3 resolutions of June 12 (attached, “Exhibit B”)

On August 11, engine/truck manufacturers Daimler, Paccar, Volvo and International sued CARB in order to nullify the Omnibus, ACT and Clean Truck Partnership (attached, OEMs v. CARB Complaint)

On August 15, the US Department of Justice (DOJ) sues CARB saying that CARB’s regulations are preempted by federal law (3 files attached, two referred to as “Complaint in Intervention” for light duty and heavy-duty CARB rules)

On August 18, the California Office of Administrative Law (AOL) declined to hear/respond to the WSTA petition concerning the CTP many issues including underground regulation claims filed June 18.

Likely, much more to come!
