Heavy-Duty Zero-Emission Vehicle Information

the road to Heavy-duty zero-emission vehicles.

Zero-Emission Goals
To meet California's health based air quality standards and greenhouse gas emission reduction goals, the trucks and buses operated in the state and the fuel they use must be transformed away from petroleum. California is working to meet the Governor’s goal of one hundred percent zero-emission transportation where feasible by 2045.

100% ZEV sales by 2035. Full transition to ZEV short-haul/drayage trucks by 2035. Full transition to ZEV buses & heavy-duty long-haul by 2045 where feasible. Full transition to ZE off-road equipment by 2035 where feasible.

Incentives
Financial incentives are critical for supporting the advancement and wide-scale deployment of zero-emission technologies while simultaneously providing immediate emission reductions to help meet our air quality and climate goals.

Monetary incentives from federal, state, and local sources have a history of demonstrating the feasibility of zero-emission technologies. Funding also helps to increase adoption of the newest technologies before they are required. Regulations also create strong incentives for businesses to develop or adopt zero-emission technologies when they can be used for compliance or have monetary value. The following programs are examples of traditional incentive programs that provide funding for zero-emission technologies.

Regulations
When developing new or amending existing regulations, CARB’s goal is to obtain emission reductions to meet federal air quality standards, minimize negative health effects in the State’s most impacted and disadvantaged communities, and to lessen climate impacts.

CARB collaborates closely with stakeholders to ensure regulations are technologically feasible and cost-effective. These regulations can require manufacturers to develop and commercialize zero-emission technologies as well as increase or accelerate user adoption of those technologies. CARB also sets certification standards through new engine and vehicle emission control regulations. The development of zero-emission certification standards are critical for the widespread deployment of zero-emission technologies through regulations and incentive programs. Below are some of the regulations that CARB currently has in place or under development to accelerate the deployment and adoption of zero-emission technologies in on-road applications:

Innovative Clean Transit Regulation ► Transitions transit buses to zero-emission and demonstrates the results as the beachhead technologies for the entire heavy-duty vehicle sector By 2026, 50% of large and 25% of small transit agency new bus purchases must be zero-emission buses By 2029, 100% of transit agency new bus purchases must be zero-emission buses By 2040, all public transit agencies must gradually transition to a 100% zero-emission bus fleet
Zero-Emission Airport Shuttle Regulation ► Transition airport ground transportation to zero-emission By end of 2027, airport shuttle fleets must have 33% of shuttles be zero-emission By end of 2035, 100% of shuttles must be zero-emission
Zero-Emission Powertrain Certification Regulation ► Sets a zero-emission powertrain standard and certification process that will help reduce variability in the quality and increase reliability of heavy-duty electric and fuel cell vehicles Ensures vehicle and powertrain information are effectively and consistently communicated to purchasers Accelerate progress towards greater vehicle reparability Certification process required by Zero-Emission Airport Shuttle Regulation starting in model year 2026 and the Advanced Clean Trucks Regulation starting in model year 2024
Advanced Clean Trucks Regulation ► Accelerate large-scale transition of zero-emission medium and heavy-duty vehicles from Class 2b to Class 8 Requires manufacturers who certify Class 2b-8 chassis or complete vehicles with combustion engines to sell zero-emission trucks as an increasing percentage of their annual California sales By 2035, zero-emission truck/chassis sales must be 55% of class 2b to class 3 truck sales, 75% of class 4 to class 8 straight truck sales, and 40% of truck tractor sales
Proposed Zero-Emission Transport Refrigeration Unit (TRU) Regulation ► Proposed regulation with the goal of transitioning truck TRUs to zero-emission Imposes stricter diesel PM emission standards for newly manufactured TRUs Requires use of lower global warming potential refrigerants
Proposed Advanced Clean Fleets Regulation ► Proposed regulation with the goal of accelerating the deployment of zero-emission medium and heavy-duty trucks Goal is to achieve a zero-emission California truck and bus fleet by 2045 where feasible, and significantly earlier for some market segments, such as last mile delivery and drayage applications CARB Board recommendation scheduled for late 2022

Zero-Emission Market
The zero-emission truck market is growing rapidly with more manufacturers coming forward with zero-emission plans all the time.

There are more than 70 different models of zero-emission vans, trucks and buses that already are commercially available from several manufacturers. Most trucks and vans operate less than 100 miles per day and several zero-emission configurations are available to serve that need. As technology advances, zero-emission trucks will become suitable for more applications. Most major truck manufacturers have announced plans to introduce market ready zero-emission trucks in the near future. There are several resources available to review the zero-emission technology that is on the market today and that will be rolled out in coming years:

Advanced Clean Trucks Regulation ► Accelerate large-scale transition of zero-emission medium and heavy-duty vehicles from Class 2b to Class 8 Requires manufacturers who certify Class 2b-8 chassis or complete vehicles with combustion engines to sell zero-emission trucks as an increasing percentage of their annual California sales By 2035, zero-emission truck/chassis sales must be 55% of class 2b to class 3 truck sales, 75% of class 4 to class 8 straight truck sales, and 40% of truck tractor sales
Proposed Zero-Emission Transport Refrigeration Unit (TRU) Regulation ► Proposed regulation with the goal of transitioning truck TRUs to zero-emission Imposes stricter diesel PM emission standards for newly manufactured TRUs Requires use of lower global warming potential refrigerants
Proposed Advanced Clean Fleets Regulation ► Proposed regulation with the goal of accelerating the deployment of zero-emission medium and heavy-duty trucks Goal is to achieve a zero-emission California truck and bus fleet by 2045 where feasible, and significantly earlier for some market segments, such as last mile delivery and drayage applications CARB Board recommendation scheduled for late 2022
