2020 Clean Air Grants for On-Road Trucks and Buses

Santa Barbara County Air Pollution Control District (District) has funding opportunities for a variety of on-road vehicle replacement projects. Grant funds are calculated based on the amount of pollutant emissions the replacement project will reduce. 

  • Projects that operate in a Low income Community as defined by AB 1550 will be prioritized for funding.  The AB 1550 map can be viewed at
  • Projects that use zero emission technology will be prioritized for funding.
  • The District may use discretion to distribute funds equitably throughout the county.

Additional Funding Sources and Information for Cleaner On-Road Vehicles

Funding  for hybrid and zero-emission trucks and buses, as well as low-NOx natural gas engines, is available through California’s Heavy-Duty Vehicle Incentive Program.

Additional funding and regulatory resources for heavy-duty truck operators can be found on the California Air Resources Board Truck Stop page.

CARB has a calculator tool to help estimate a potential grant amount. Please note that the District is only funding zero-emission and low-Nox replacement projects.
