Industry Initiatives

The California Air Resources Board (CARB) and other local, state, and federal partners have invested heavily in the deployment of zero-emission trucks and buses to meet California’s health-based air quality standards and greenhouse gas reduction goals. 

This dashboard tracks the ongoing progress of putting zero-emission trucks and buses on the road in California. Each data point represents a vehicle owned by a fleet, either a battery-electric vehicle (BEV) or fuel cell electric vehicle (FCEV). Contextual information such as location, vehicle type, and amount of funding awarded for each vehicle is included. 

A key feature of the dashboard is providing information over multiple geographic layers including Air District, County, State Assembly District, State Senate District, and Disadvantaged Community Status. This initial iteration of the dashboard includes deployed medium-duty and heavy-duty zero-emission vehicles, such as trucks and buses, and in the future will be expanded to include off-road vehicles, light‑duty vehicles, and vehicles supported by other funding or regulatory programs.

The data presented here includes the following funding sources:

• Hybrid and Zero-Emission Truck and Bus Voucher Incentive Project (HVIP) 
• California VW Mitigation Trust 
• Carl Moyer Program 
• Community Air Protection (CAP) Incentives 
• Clean Mobility In Schools (CMIS) Pilot Projects
• Rural School Bus Pilot Project 
• Sacramento Regional Zero-Emission School Bus Deployment Project 
• U.S. EPA Diesel Emission Reduction Act (DERA) State Allocation
• Proposition 1B: Goods Movement Emission Reduction Program

As this dashboard was created from many separate datasets, every effort was made to ensure consistency and similarity of information across programs. The location coordinates are generated from the address provided by the funding program – if unavailable, zip code was used to approximate location. Vehicle type was classified consistent with the program that funded the vehicle or by using a combination of Gross Vehicle Weight Rating (GVWR) and vocational use information. For some vehicles, funding information was not available.

Investing in California’s school bus fleet is a collective effort amongst agencies on the local, state, and federal level. California is leading the nation in cleaning up the state’s school bus fleet to improve air quality for students and surrounding communities.

Considering investments from CARB and the California Energy Commission, the state has supported about 1,800 zero-emission school buses, and 570 of those are already operating in 200 school districts across California. The Legislature has appropriated another $1.8 billion over the next five years for zero-emission school buses and associated charging infrastructure.

This dashboard shows the zero-emission school buses that have been delivered or are projected to be delivered from various CARB-funded and CARB-implemented school bus funding sources.

This dashboard is updated on a biannual basis. A copy of the data that was used to populate this dashboard is available for download. The data presented here includes the following school bus funding sources: 

• HVIP 
• Rural School Bus Pilot Project 
• CA VW Mitigation Trust 
• Community Air Protection Incentives 
• Carl Moyer Program 
• Sacramento Regional ZE School Bus Deployment Project 
• US EPA Diesel Emission Reduction Act (DERA) State Allocation
• Clean Mobility In Schools Pilot Projects 

The California Energy Commission (CEC) tracks zero-emission school bus deployments from the CEC School Bus Replacement Program on the CEC School Bus Delivery Tracker.

For more information on state school bus incentives and the projected need for funding, please read the annual SB 1403 State School Bus Incentive Programs Report.

Definition of Terms:
Delivered: zero-emission school bus has been received by the school district.
Projected: Contract for zero-emission school bus has been executed, but delivery is pending.
