CARB’S ADVANCED CLEAN FLEETS REGULATION
The California Air Resources Board’s (CARB) Advanced Clean Fleets (ACF) regulation establishes requirements for public agencies (including public utilities) to purchase a specified percentage of Zero-Emission Vehicles (ZEV) as part of their new vehicle purchases. Starting in 2024, fleet owners are required to add ZEVs per the following schedule. Starting January 1, 2024, 50% of the total number of vehicle additions to the fleet in each calendar year must be ZEVs. Starting January 1, 2027, 100% of the total number of vehicle additions to the fleet in each calendar year must be ZEVs. As an alternative, fleet managers may choose CARB’s Milestone Option which de-links the obligation to integrate ZEVs from the fleet manager’s new-vehicle purchase decision, and instead, establishes a commitment to convert portions of the fleet by target dates specified by the Air Resources Board. To establish a baseline that CARB can effectively monitor, fleet managers are required to provide a complete list and description of all vehicles in the current fleet by April of 2024.
