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 though workshops and fleets visits. Funding opportunities available through CAF can be found on this website.

RAQC Awarded ARRA Funds

RAQC Awarded ARRA Funds

The U.S. EPA awarded RAQC 1.25M of ARRA grant funds in July 2009 to encourage economic growth and job preservation/creation by employing vendors to reduce harmful diesel emissions and fuel consumption in the Ozone Nonattainment Area and along the Colorado Front Range. Since that time, funding has been used to install auxiliary power units on over-the-road semi-trucks as well as diesel oxidation catalysts and engine preheaters on school buses. In upcoming months, the RAQC will install thermal coolers, full sets of SmartWay low-rolling resistance tires, SmartWay trailer gap fairings and more auxiliary power units on vehicles throughout the state.
