CA Zero-Emission Vehicle Fleet program

The California Air Resources Board (CARB) Zero-Emission Vehicle Fleet program is California’s overall plan to transition the vehicle fleets in use in California to zero-emission vehicles (ZEVs).
There are two programs that are part of the Zero-Emission Vehicle Fleet program that affect motor carriers: the Advanced Clean Trucks (ACT) and Advanced Clean Fleet (ACF) regulations.
Under the ACT rule, manufacturers must sell a specific percentage of ZEVs to be able to sell vehicles in California. Note that many other states are or will be adopting regulations similar to CARB’s ACT.
Under the ACF regulation, state and local government fleets must transition to ZEVs. The transition and timeline will depend on the type of fleet and the type of vehicles the fleet operates.
