City of Denver, Colorado:  The City of Denver’s Department of Public Works began using B20 in 60 vehicles in 2004 during a pilot program (about 52,000 gallons).  Since then, they have gradually increased their biodiesel use and now fuel the City’s entire diesel fleet of approximately 800 vehicles/equipment with B20.  That does not include Denver International Airport which also uses B20.  The City expects to use one million gallons of biodiesel in 2007 and the fuel is now available at all fueling locations. 

According to Nancy Kuhn, Operations Administrator, “Denver made the switch to biodiesel to benefit human health and the environment, to reduce harmful emissions and the City's dependency on foreign oil. We knew it would be easy to implement with no modifications required to the the vehicles, maintenance facilities, or fueling infrastructure. The fuel was also readily available.”
