Join us to learn about the many choices drivers have when it comes to clean fuel options and today’s ever-changing alternative fuel market. Colleen will share with us why Clean Cities encourages the use of clean fuels — biodiesel, ethanol (E85), compressed natural gas, propane, hybrid electric, fuel cell and hydrogen technologies — in local fleets and other vehicles, and promotes the advancement of local refueling infrastructure for these vehicles. This show made possible due to the generous support of Pima Association of Governments.



  • What is the mission of Clean Cities? To reduce dependence on petroleum by deploying alternative fuels and alternative fueled vehicles.
  • Clean Cities coalition is made up of huge institutions (like the University of Arizona) to small, local businesses and organizations. Together, we are all trying to introduce alternative fuel into some part of our operations.
  • There have been amazing improvements around Tucson with energy use and reduction of greenhouse gases. A few “eco-champions” include:

– The City of Tucson: A good portion of their trash hauler fleet has moved to compressed natural gas instead of belching diesel fuel – good for the community and for the air! By doing this, the city has reduced their greenhouse gas emissions by 328 tons in one year!

– Amphitheater School District: The district exchanged 22 of their school buses for buses that use alternative fuel. The buses were purchased with the help of an EPA grant  – greatly helping a small school district and reducing greenhouse gases!

– Marana Unified School District: This district received more than $467,000 in rebate funding for committing to purchase school buses that will use alternative fuel. This rebate was the largest rebate funding received by a school district in the United States!

  • Clean Cities coalition is involved in many great partnerships. Listen to the full podcast to learn how they are working with The National Parks Projects and the Department of Energy!
