Our Mission

Clean Cities coalitions foster the economic, environmental, and energy security of the United States by working locally to advance affordable, domestic transportation fuels and technologies.

In 2017, the United States imported 19% of the approximately 19.9 million barrels of petroleum it consumed per day. Because transportation accounts for nearly three-fourths of total U.S. petroleum consumption, improving efficiency and reducing costs in this sector supports our economy and our energy security.

Increased economic and energy security aren't the only benefits. Widespread use of alternative fuels and advanced vehicles could reduce the emissions that impact our air quality and public health.

As part of the U.S. Department of Energy's (DOE) Vehicle Technologies Office (VTO), Clean Cities coalitions foster the nation's economic, environmental, and energy security by working locally to advance affordable, domestic transportation fuels and technologies. Clean Cities coalitions have saved more than 8.5 billion gallons of petroleum since its inception in 1993.

Who We Are

Nearly 100 local coalitions serve as the foundation of Clean Cities by working in communities across the country to implement alternative fuels and advanced vehicle technologies. Clean Cities coalitions are comprised of businesses, fuel providers, vehicle fleets, state and local government agencies, and community organizations. Each coalition is led by an on-the-ground Clean Cities coordinator, who tailors projects and activities to capitalize on the unique opportunities in their communities. Nationwide, nearly 15,000 stakeholders participate in Clean Cities coalitions, and through their collective efforts they are transforming local and regional transportation markets.

What We Do

At the national level, VTO develops partnerships and provides publications, tools, and other resources. At the local level, coalitions leverage these resources to create networks of local stakeholders and provide technical assistance to fleets implementing alternative and renewable fuels, idle-reduction measures, fuel economy improvements, and emerging transportation technologies.

Together, Clean Cities' efforts support a broad set of approaches that improve transportation efficiency at the local, state, and national levels. Clean Cities' activities include:

  • Building partnerships with local coalitions of public- and private-sector transportation stakeholders
  • Developing unbiased and objective information resources about alternative fuels, advanced vehicles, and other strategies that improve transportation efficiency and reduce costs
  • Advancing interactive, data-driven online tools to help stakeholders evaluate options and achieve goals
  • Collecting and sharing best practices, data, and lessons learned to inform choices and build a strong national network
  • Providing technical assistance to help fleets deploy alternative fuels, advanced vehicles, and idle-reduction measures
  • Working with industry partners and fleets to identify and address technology barriers
  • Empowering local decision makers to successfully identify and implement new transportation strategies
  • Seeding local alternative fuels markets through projects that deploy vehicles and fueling infrastructure.

Why We're Here

Clean Cities dates back to the Alternative Motor Fuels Act of 1988 and the Clean Air Act Amendments of 1990. These laws, which encouraged the production and use of alternative fuel vehicles (AFVs) and the reduction of vehicle emissions, led to the creation of the Alternative Fuels Data Center (AFDC) in 1991. The AFDC's mission was to collect, analyze, and distribute data used to evaluate alternative fuels and vehicles.

In 1992, the enactment of the Energy Policy Act of 1992 (EPAct) required certain vehicle fleets to acquire AFVs. Subsequently, DOE created Clean Cities in 1993 to provide informational, technical, and financial resources to EPAct-regulated fleets and voluntary adopters of alternative fuels and vehicles.

The AFDC became and continues to be the clearinghouse for these resources. Its sister website, FuelEconomy.gov, provides consumers with information on fuel economy, emissions, and energy impact of light-duty vehicles, based on vehicle data from the U.S. Environmental Protection Agency. The site also provides tips for drivers on maximizing fuel efficiency. FuelEconomy.gov was created in response to DOE's requirement under the 1975 Energy Policy and Conservation Act to publish and distribute an annual fuel economy guide for consumers.
