Ford, General Motors, Navistar, and several other global leading truck manufacturers have joined the Clean Truck Partnership with the California Air Resources Board (CARB).

The collaboration marks a commitment from the companies to meet California’s vehicle standards that will require the sale and adoption of zero-emissions technology in the state, regardless of whether any other entity challenges California’s authority to set more stringent emissions standards under the federal Clean Air Act.

The Clean Truck Partnership has been joined some of the world’s leading manufacturers: Cummins, Daimler Truck North America, Ford Motor Company, General Motors Company, Hino Motors Limited, Isuzu Technical Center of America, Navistar, PACCAR, Stellantis, Truck and Engine Manufacturers Association, and Volvo Group North America.

The partnership was also joined by the Truck and Engine Manufacturers Association that advances the development of zero-emission vehicles (ZEVs) for the commercial trucking industry.

In turn, CARB has agreed to work collaboratively with manufacturers to provide reasonable lead time to meet CARB’s requirements and before imposing new regulations and to support the development of necessary ZEV infrastructure.

CARB chair, Liane Randolph, said:

“The unprecedented collaboration between California regulators and truck manufacturers marks a new era in our zero-emission future, where we work together to address the needs of both the trucking industry and the Californians who deserve to breathe clean air,”


“This agreement makes it clear that we have shared goals to tackle pollution and climate change and to ensure the success of the truck owners and operators who provide critical services to California’s economy.”

The terms of the Clean Truck Partnership include the promise of truck manufacturers to meet CARB’s zero-emission and criteria pollutant regulations in the state. Read the full agreement here.

The Clean Truck Partnership comes as California prepares for implementation of its landmark rules that put in place a phased-in transition toward 100% sale and use of zero-emissions technology for medium- and-heavy duty vehicles under CARB’s Advanced Clean Trucks and Advanced Clean Fleets rule by 2045.

John Rich, Chief Technology Officer for PACCAR, said:

“PACCAR is committed to supporting the environmental goals of California and the nation as a whole and welcome the harmonization of future emissions regulation. This agreement provides regulatory certainty and supports a balanced transition to zero emissions by ensuring continued supply of product into California and opt-in states.”
