School Bus Investments

Older, higher-polluting, diesel school buses are harmful to children’s health because they expose children to toxic diesel particulate matter. Incentives are a key part of CARB’s efforts to ensure that clean school buses are operating across state. CARB has administered incentive programs to support the replacement of the State’s aging school bus fleet for decades, and the State has made significant progress in cleaning up the school bus fleet. The Hybrid & Zero-Emission Truck & Bus Voucher Incentive Program; (HVIP) Public School Bus Set-Aside and Rural School Bus Pilot Project represent two of CARB’s funding programs that focus exclusively on the replacement of older combustion school buses with cleaner, less polluting options. While not exclusively focused on school buses, HVIP and Clean Mobility in Schools can also support the purchase of zero-emission school buses as well as other vehicle and equipment types commonly used at public schools.
