Clean Cities

Colorado and National Programs

Clean Cities is a locally based government and industry partnership coordinated by the U.S. Department of Energy (US DOE) to expand the use of alternatives to gasoline and diesel fuels.

The Clean Cities program promotes the use of alternative fuels by fleets in order to:

  1. Reduce U.S. dependence upon foreign transportation fuels. The U.S. imports four million barrels of oil a day.
  2. Reduce air pollution and improve public health. Alterative fuels have the potential to significantly reduce motor vehicle emissions.
  3. Educate the public on the benefits of alternative fuels and alterative fuel vehicles (AFV).
  4. Encourage the development of an AFV infrastructure.
Alterative fuels include propane, compressed natural gas, ethanol, methanol, liquid natural gas, electricity, and biodiesel.

The Clean Cities program began in 1994 and Philadelphia received the first Clean Cities designation.

Cities become designated by:

  • appointing a coordinator,
  • holding stakeholder meetings,
  • developing a program plan, and
  • writing a Memorandum of Understanding (MOU) that guides subsequent work. The MOU is a non-binding agreement with US DOE to advance the use of AFVs among fleets.
