The Tucson Regional Clean Cities Coalition promotes the use of clean fuels and clean-fuel vehicles in partnership with the U.S. Department of Energy's Clean Cities Program. The coalition coordinates with member jurisdictions to develop clean-fueling infrastructure, advance the understanding of the benefits of clean-fuel vehicles and work to develop Clean Corridors on interstate highways and trade routes.

The coalition meets bi-monthly on the third Wednesday of the month from 2 p.m. to 4 p.m.
