Medium- and Heavy-Duty Zero Emission Vehicle (ZEV)
Requirement
The California Air Resources Board’s (ARB) Advanced Clean Truck Program requires all new medium- and heavy-duty vehicles sold in California to be a ZEV by 2045. Zero-emission technologies include all-electric and fuel cell electric vehicles.
Beginning in 2024, manufacturers seeking ARB certification for Class 2b through Class 8 chassis or complete vehicles with combustion engines will be required to sell zero-emission trucks as an increasing percentage of their annual California sales. Manufacturers must achieve the following annual sales percentages for medium- and heavy-duty ZEVs sold in California:
ZEV Sales Percentages
| Vehicle Model Year (MY) |
Class 2b-3 | Class 4-5 |
Class 6-8, excluding tractors |
Class 7-8 Tractors |
|---|---|---|---|---|
| 2024 | 5% | 9% | 9% | 5% |
| 2025 | 7% | 11% | 11% | 7% |
| 2026 | 10% | 13% | 13% | 10% |
| 2027 | 15% | 20% | 20% | 15% |
| 2028 | 20% | 30% | 30% | 20% |
| 2029 | 25% | 40% | 40% | 25% |
| 2030 | 30% | 50% | 50% | 30% |
| 2031 | 35% | 55% | 55% | 35% |
| 2032 | 40% | 60% | 60% | 40% |
| 2033 | 45% | 65% | 65% | 45% |
| 2034 | 50% | 70% | 70% | 50% |
| 2035 and future years | 55% | 75% | 75% | 55% |
*Excludes pickup trucks for 2024-2026 MYs
Additionally, entities with annual gross revenues greater than $50 million, fleet owners with 50 or more medium- and heavy-duty vehicles, and any California government or federal agency with one or more vehicles over 8,500 pounds must
report their existing fleet operations to ensure fleets are purchasing and placing zero-emission trucks in the correct service locations.

Zero-Emission Airport Shuttle Requirement
By 2035, all airport fixed-route shuttle fleets must transition to 100% zero-emission vehicles (ZEVs). Zero-emission shuttle technologies include all-electric or fuel-cell electric technologies.
Starting in 2022, shuttle fleets must report the
details of their vehicles to the California Air Resources Board (ARB).
Starting in 2023, if fleets replace a ZEV shuttle, the replacement must be a ZEV.
For additional terms and conditions, visit ARB’s Zero-Emission Airport Shuttle website. (Reference Resolution Number 19-8, 2019)
