Clean Cities Goals and Accomplishments

Clean Cities' primary goal is to cut petroleum use in the United States by 2.5 billion gallons per year by 2020. To achieve this goal, Clean Cities employs three strategies:

  • Replace petroleum with alternative and renewable fuels
  • Reduce petroleum consumption through smarter driving practices and fuel economy improvements
  • Eliminate petroleum use through idle reduction and other fuel-saving technologies and practices.

Clean Cities coalitions and stakeholders have saved more than 5 billion gallons of petroleum since the program's inception in 1993. Clean Cities efforts have helped deploy thousands of alternative fuel vehicles and the fueling stations needed to serve them, aided in the elimination of millions of hours of vehicle idling, and helped accelerate the entry of electric-drive vehicles into the marketplace.

Clean Cities is aiming to cut U.S. petroleum fuel use by 2.5 billion gallons per year.

*Petroleum savings include both gasoline and diesel fuel. Savings are measured in gasoline-gallon equivalents (GGEs), representing a quantity of fuel with the same energy content as a gallon of gasoline.

In 2012, Clean Cities saved 348 million gallons of petroleum with the use of alternative fuel vehicles. Source: Clean Cities annual metrics reports

Coalitions have made great strides in deploying alternative fuel vehicles (AFVs) in the United States. In 2012, more than 540,000 of the AFVs on the road were deployed with help from Clean Cities efforts. Source: Clean Cities annual metrics reports

Since 1993, Clean Cities has funded more than 500 transportation projects nationwide through a competitive application process. Clean Cities has distributed $377 million in project awards, which have leveraged an additional $740 million in matching funds and in-kind contributions from other organizations in the public and private sectors.
