Tucson Clean Cities
The Tucson Clean Cities works with vehicle fleets, fuel providers, community leaders, and other stakeholders to reduce petroleum use in transportation.
Colleen Crowninshield has worked for Pima Association of Governments since 1994. In 2001, she assumed the Tucson Clean Cities responsibilities and became the full-time coordinator of the program. She also runs the Solar Partnership in Southern Arizona.
Colleen has made many advances in the Tucson Clean Cities program. She opened the first compressed natural gas, E85, and biodiesel retail stations, and in 2008, her program displaced more than 12 million gallons of petroleum.
In 2005, Crowninshield was named the U.S. Department of Energy Clean Cities Coordinator of the Year.
