Zero-Emission Transit Bus Requirement
By 2040, all public transit agencies must transition to 100% zero-emission bus fleets. Zero-emission bus technologies include battery-electric or fuel cell electric. Transit agencies must purchase or operate a minimum number of zero-emission buses according to the following schedules:
| Large Transit Agency | Small Transit Agency | |
|---|---|---|
| January 1, 2023 | 25% of the total number of new bus purchases in each calendar year must be zero-emission buses | No requirement |
| January 1, 2026 | 50% of the total number of new bus purchases in each calendar year must be zero-emission buses | 25% of the total number of new bus purchases in each calendar year must be zero-emission buses |
| January 1, 2029 | All new bus purchases must be zero-emission buses | All new bus purchases must be zero-emission buses |
Each transit agency will submit a plan demonstrating how it will purchase clean buses, develop infrastructure, train personnel, and other required details. Large transit agencies must submit a plan in 2020 and small agencies must submit a plan in 2023. Additional rules and requirements apply.
