    Tennessee Sustainable Transportation Forum and Expo

    The Tennessee Sustainable Transportation Forum & Expo (STF&E) is an annual conference 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.

    Each year, STF&E features an alternative fuel vehicle and equipment showcase as well as a luncheon that honors both winners of the Tennessee Sustainable Transportation Awards (TSTAs) and new inductees to the Tennessee Green Fleets (TGF) program. Explore the links below to learn more about these programs or to find information on past STF&E events.

    Tennessee Sustainable Transportation Awards

    The 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. Eligible entities include: federal, State, and local governments; commercial, nonprofit, and industrial organizations; public and private institutions of higher education; and utilities.

    Nominations for the 2019 TSTAs have closed.

    Tennessee Green Fleets

    The 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 (GHG) emissions, and implement alternative fuel vehicles.

    Applications for this year's TGF certification are due by June 30.

    Alternative Fuel Vehicle and Equipment Showcase

    Each year, Tennessee Clean Fuels assembles an alternative fuel vehicle and equipment showcase for all STF&E attendees. 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. The showcase highlights local fleets that have adopted alternative fuels, demonstrating the breadth of fleet innovation occurring in Tennessee. Find information on previous showcases here.

    Previous STF&E Events

    Since the forum’s inception in 2015, STF&E events have 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, particularly in how such projects and ideas can be implemented in Tennessee to serve the public good.
