Valley of the Sun Clean Cities (Phoenix) Coalition
Clean Cities Coordinators
Bill Sheaffer began serving as coordinator of the Valley of the Sun Clean Cities coalition in 2002 and now serves as the executive director of this all-volunteer coalition. The coalition has been actively involved with the state legislature as well as the key agencies, municipalities, and utilities.
The region reported 30.5 million gallons of petroleum fuel displaced in 2008, which included the new light rail system, new renewable fuel plants, and the lead of Valley Metro Transit System and Sky Harbor Airport—the nation's largest users of compressed natural gas and liquid natural gas.
Sheaffer also serves on the Scottsdale Energy Committee and as vice president of an Arizona biodiesel producer. He formerly served on the technical committee of South Coast Air Quality Management District and Energy Foundation of the University of California, Riverside. Sheaffer is active in outreach as a guest speaker at Arizona State University, Thunderbird School of International Business, University of Southern California, University of California–Los Angeles, and air quality and municipal organizations.
