The California Air Resources Board Friday voted unanimously to finalize its Advanced Clean Fleets (ACF) rule, a sweeping set of regulations that requires all new medium- and heavy-duty vehicles sold or registered in the state to be zero-emission by 2036 and requires all trucks to be zero-emission by 2042.
CARB estimates that, of the 1.8 million medium- and heavy-duty vehicles operating daily in California, 532,000 will be subject to ACF fleet requirements.
Figure 2 shows how many vehicles in certain groups of vehicle classes are estimated to be subject to the proposed regulation, and what percentage of the vehicles that operate in California that is. The proposed regulation focuses on the truck types that pollute the most; 67 percent of all Class 7-8 tractors, the largest polluters, will be covered.
The regulation has heavy implications for motor carriers in the state, as it bars truck manufacturers from selling any combustion-engine trucks in the state by 2036. The 100% ZEV manufacture sales requirement was moved up to 2036 from the original 2040 start date.

The regulation applies to fleets performing drayage operations, those owned by state, local, and federal government agencies and "high priority fleets." High priority fleets are defined as entities that own, operate or direct at least one vehicle in California, and that have either $50 million or more in gross annual revenues, or that own, operate, or have common ownership or control of a total of 50 or more vehicles (excluding light-duty package delivery vehicles). The regulation affects medium- and heavy-duty on-road vehicles with a gross vehicle weight rating greater than 8,500 pounds, off-road yard tractors and light-duty mail and package delivery vehicles.
