Air District funding is available to help upgrade or replace on-road diesel trucks with newer, lower-emission equipment.


The Air District has the following on-road truck and bus programs:

  • Carl Moyer Program – The Carl Moyer Program provides vouchers or grants for public or private fleets to replace trucks and buses, repower engines, convert power (fuel) systems, and install battery-charging or fuel infrastructure for on-road equipment.   
  • TFCA Heavy-Duty EVs Program – The Transportation Fund for Clean Air (TFCA) Heavy-duty EV program provides funding for Zero- and Partial-Zero-Emissions Medium, Heavy-Duty Vehicles and Urban Buses.
  • Goods Movement Program – The Proposition 1B: Goods Movement Emission Reduction Program aims to quickly reduce air pollution emissions and health risk from freight movement along California trade corridors.  Through this program over 2,500 trucks have been replaced or retrofitted.
