Clean Cities Top 20 Facts

Clean Cities has provided top-notch technical assistance for more than 20 years

Clean Cities coalitions and their stakeholders implement thousands of projects every year within their local communities—all in the pursuit of cutting U.S. petroleum use. These projects are aided by the robust collection of information and technical resources within the Clean Cities program framework. And one of the most valuable of these resources is the Clean Cities Technical Response Service (TRS).

As far back as 1992, the service began as the National Alternative Fuels and Clean Cities Hotlines before being combined into the current Clean Cities TRS in 2005.

Learn why Margaret Larson (Honolulu Clean Cities co-coordinator) said, "The Technical Response Service is my best friend" in this case study.

But the TRS isn't just available to Clean Cities coordinators. It's also for stakeholders and people like you. The staff keeps abreast of industry trends and current research and publications, and they are experts at identifying the right resources to assist you.

Stakeholders in particular have relied on the TRS to help them:

  • Explore the benefits of various fuels and technologies
  • Quantify the costs of infrastructure and vehicles and calculate returns on investment
  • Identify incentives that will help offset the costs of vehicle acquisitions and infrastructure development
  • Understand standards, laws, regulations, and requirements
  • Locate fueling stations and related information
  • Identify case studies, best practices, and lessons learned.

Consider the TRS your go-to source for information. You can reach the service at or 800-254-6735. Keep this contact information handy or add it to your contacts list.

Have a particularly tough challenge? Clean Cities offers hands-on technical assistance for eligible projects through Tiger Teams. These technical experts help Clean Cities coordinators, stakeholders, equipment manufacturers, and fuel providers overcome obstacles to deploying alternative fuels and advanced vehicles.
