Jonathan Overly

Jonathan Overly founded the East Tennessee Clean Fuels Coalition (ETCleanFuels) in 2001 and has spoken to thousands of people across the state including hundreds of companies and organizations about partnering to expand their alternative fuel use. Overly currently serves on the Strategic Planning Group for the EPA Region 4 STRIDE Collaborative, on the Board of Directors for Transportation Energy Partners, and on the City of Knoxville's Mayor's Climate Council on the Transportation Technical Working Group. Overly has a Master of Science in Environmental Engineering from the University of Tennessee at Knoxville. He has won several regional and state awards for advancing alternative fuels and improving air quality, including from the State of Tennessee and EPA Region 4. In 2015, Overly was inducted into the Clean Cities Hall of Fame, joining a slew of other great directors that work hard to show dedication and leadership to the Clean Cities mission and serving fleets in their communities.

Some of ETCleanFuels' major initiatives include:

  • Southeastern Corridor Council – Overly started this relatively new entity that is bringing together coalitions and state DOT representatives from 11 states to make effective, consistent plans for adding corridor signage along all of our interstates.
  • Fuels Fix alt-fuel news website and email – This Clean Cities stories and alternative fuel news website provides monthly updates to subscribers on alternative fuels news across the U.S. Daniel Siksay leads this effort.
  • Drive Electric TN – This partnership is the official statewide effort for advancing EVs in Tennessee and has the participation of numerous entities across the entire state. DET is housed in ETCleanFuels, and Virginia Salazar Buda is the program coordinator.
  • Tennessee Green Fleets Certification Program – Tennessee's only fleet certification program that reviews any size fleet to assess it based on reduced petroleum use and emission reductions.
