Between 2014 and 2018, ALT Fuels Colorado operated with funding from the Federal Highway Administration’s (FHWA) Congestion Mitigation and Air Quality Improvement (CMAQ) program.  With this funding, the program incentivized the purchased of over 800 alternatively fueled vehicles between September 2014 and January 2019.  This funding is no longer available.  For a list of fleets awarded CMAQ funding, click here.  In 2018 the ALT Fuels Colorado (AFC) program was allocated additional funding from a diesel emissions settlement.  This funding is managed in partnership with the Colorado Department of Health and Environment, the Colorado Department of Transportation, and the Colorado Energy Office.  For a list of fleets awarded settlement funding through the ALT Fuels Colorado program, click here.  For a list of projects awarded settlement funding from programs other than ALT Fuels Colorado, please click here.
