Clean Air Fleets

Clean Air Fleets (CAF) is a regional public-private initiative of the Regional Air Quality Council (RAQC) to help on- and off-road diesel operators voluntarily reduce diesel emissions while saving money. CAF identifies opportunities and leverages funds from a variety of sources to implement effective programs that meet the specific needs of fleets in the Denver metro region. CAF, started in 2003, provides information on, and funding for, retrofit technologies and advances in diesel emissions mitigation. Staff promotes awareness of current diesel issues through workshops and fleets visits. Funding opportunities available through CAF can be found on this website.
