Clean Cities marked a major milestone in 2013, celebrating 20 years of progress in cutting petroleum use in transportation. Through the work of local coalitions across the country, by 2013 Clean Cities had worked for two decades to advance the deployment of alternative and renewable fuels, advanced vehicles, fuel economy improvements, idle-reduction measures, and new technologies as they emerge. The Clean Cities 20th anniversary event was held June 24, 2013, in Washington, D.C.
