California, truck manufacturers agree on future emission regulations

6 July 2023

The California Air Resources Board (CARB) announced a Clean Truck Partnership today with the leading US truck manufacturers and the Truck and Engine Manufacturers Association (EMA). The CARB-industry agreement advances the development of zero-emission vehicles (ZEVs) for the commercial trucking industry, which includes flexibility for manufacturers to meet emissions requirements while still reaching the state’s climate and emission reduction goals, CARB said in a press release.

The Clean Truck Partnership includes Cummins, Inc., Daimler Truck North America, Ford Motor Company, General Motors Company, Hino Motors Limited, Inc., Izuzu Technical Center of America, Inc., Navistar, Inc., Stellantis N.V., Truck and Engine Manufacturers Association, and Volvo Group North America.

The Clean Truck Partnership companies made a commitment 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. 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.

The key terms of the Clean Truck Partnership include:

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 (ACT) and Advanced Clean Fleets (ACF) rule by 2045. In March, the Biden administration approved California’s waiver under the federal Clean Air Act that allows the state to require zero-emissions technology for trucks. The ACT and ACF regulations are facing legal challenges from Republican state attorneys general, oil industry, farming, and truck driver groups.
