CARB: Zero-Emissions Vehicle Fleet Program

Scope

All drayage, high priority, and government fleets operating in California.

Regulatory citations

• Various California Code of Regulations

Key definitions

• California Air Resources Board (CARB): The state agency in California charged with controlling air pollution.
• Drayage fleet: A fleet that operates drayage vehicles.
• Drayage vehicles: Covered vehicles that operate into, in, or out of port and rail facilities.
• High priority fleet: A fleet that operates covered vehicles in California and have:
  • 50 or more covered vehicles operating in California, or
  • One covered vehicle operating in California and an annual revenue of $50 million or more (based on tax records filed with the Internal Revenue Service).

• Truck Regulations Upload, Compliance, and Reporting System (TRUCRS): TRUCRS is used for meeting reporting requirements for several in-use fleet regulations, including ACF.
• Zero emissions vehicle (ZEV): A vehicle that CARB has certified as operating with zero emissions. Examples include battery-powered vehicles and vehicles powered by hydrogen fuel cells.

Summary of requirements

There are two programs that are part of the Zero-Emissions Vehicle Fleet program that affect motor carriers:

• Advanced Clean Truck (ACT), and
• Advanced Clean Fleet (ACF).

Under the Advanced Clean Truck (ACT) rule, manufacturers must sell a specific percentage of zero-emissions vehicles (ZEVs) to be able to sell vehicles in California. Note that other states are or will be adopting regulations similar to CARB’s ACT.

Under the Advanced Clean Fleet (ACF) regulation, drayage truck, high priority fleet, and government fleets must transition to zero-emissions vehicles. The transition and timeline depend on the type of fleet and the type of vehicles the fleet operates. To verify that fleets are making the transition, fleets must register their California vehicles (vehicles used in California) in CARB’s TRUCRS system.
