Tennessee Sustainable Transportation Forum and Expo

The Tennessee Sustainable Transportation Forum & Expo (STF&E) is an annual conference organized by the Tennessee Department of Environment & Conservation, the Tennessee Department of Transportation, and Tennessee Clean Fuels where attendees share and discover projects that can reshape what is possible in transportation and mobility. The research, technology, planning, and policy developments shared at STF&E aim to improve transportation efficiency, reduce vehicle emissions, and address the mobility needs of all. Panelists and speakers from across the country highlight best practices to transform transportation systems efficiently, affordably, and sustainably.

In 2025, the Tennessee Sustainable Transportation Forum & Expo again joined with the Tennessee Smart Mobility Expo in partnership with TennSMART, a statewide consortium that brings together leaders from the public and private sector to accelerate the development and deployment of smart mobility innovations. The Smart Mobility Expo was held April 2-3 at the Music City Center in Nashville. The Expo is a showcase of the technology research and development occurring right here in the Volunteer State, from the latest on EV charging and grid security to vehicle-to-infrastructure technology and freight logistics.

Alternative Fuel Vehicle and Equipment Showcase

Each year, the Tennessee Sustainable Transportation Forum & Expo includes an Alternative Fuel Vehicle and Equipment Showcase, which allows attendees to experience different alternative fuel technologies hands-on and engage with alternative fuel experts to learn more about the benefits these technologies can bring to a fleet. Past participants have exhibited electric, hybrid, propane, compressed or liquefied natural gas (CNG or LNG), biofuel (biodiesel or ethanol), and hydrogen vehicles and equipment from across the state. 

Tennessee Sustainable Transportation Awards

The Tennessee Sustainable Transportation Awards (TSTAs) recognize outstanding initiatives to improve the efficiency, accessibility, affordability, and sustainability of transportation systems in the state, consistent with ongoing efforts to improve the health and well-being of Tennesseans, provide for a strong economy, and protect and enhance our state’s natural resources.

Tennessee Green Fleets

The Tennessee Green Fleets (TGF) program offers an opportunity for Tennessee fleets to receive certification for their transportation efficiency efforts. Organized by Tennessee Clean Fuels, TGF certification is based on an applicant’s vehicle data and fleet fuel use. The TGF program recognizes fleets based on actions taken to reduce petroleum consumption, lessen greenhouse gas emissions, and implement alternative fuel vehicles.

Previous STF&E Events

Since the event’s inception in 2015, the Tennessee Sustainable Transportation Forum and Expo (STF&E) has been held in Memphis, Chattanooga, Nashville, and Knoxville. While the specific themes for each forum have changed from year to year, STF&E has always celebrated new achievements and opportunities in sustainable transportation.
