Welcome to the Clean Air Fleets (CAF) web site. CAF is a public-private initiative to educate on- and off-road diesel operators on how to voluntarily reduce diesel emissions while saving money. The CAF program will provide information on, and funding for, advanced retrofit technologies and fuels to reduce emissions. The CAF web site will provide the latest information on advances in diesel engine, emission control, and idling reduction technology, alternative fuels, engine and fuel standards, and much more.

In addition to providing up-to-date information on diesel-related issues and technologies, CAF will further educate fleet operators through conferences and workshops. Be sure to check out the funding opportunities available through CAF for retrofit and alternative fuel projects.
