On Wednesday October 2, 2019, Tennessee Clean Fuels certified five new fleets for their emission reductions via the “Tennessee Green Fleets” Certification Program. The fleets including the BNA bus and shuttle operations fleet managed by ABM Aviation at the Nashville airport, Oak Ridge National Lab’s (ORNL) fleet in Oak Ridge, Waste Management’s compressed natural gas fleet operating out of Jackson, TN, the Tennessee State Parks’ fleet of electric golf carts across the state at state golf courses, and last but not least Clean Sweep, Inc.‘s fleet of propane-powered street sweepers in Chattanooga - the first fleet in Chattanooga to become TNGreenFleets certified.
The fleets were recognized at the University of Tennessee, Knoxville during the fifth annual Sustainable Transportation Forum & Expo , which is managed by the Tennessee Department of Environment and Conservation (TDEC), Tennessee Department of Transportation (TDOT) and TNCleanFuels. Two of the fleets utilize CNG as their primary alternative fuel (WM, ABM Aviation), two fleets have electric vehicles in their fleet (Tennessee Golf Trail, ORNL), one uses propane autogas as its primary alternative fuel (Clean Sweep), and one fleet utilizes both of the biofuels E85 ethanol and B20 biodiesel as its primary alternative fuel (ORNL). They are an excellent representation of the diversity of alternative fuels that are used across Tennessee.
The Tennessee Green Fleets Certification Program was developed jointly by Middle-West and East Tennessee Clean Fuels. It utilizes performance-based metrics to analyze any fleet’s vehicle and fuel-use data and compare new actions they have taken to what their footprint would have looked like without those actions. A points-based, three-star system allows for certification at the 1-, 2- or 3-star level.
The Program's goal is to reduce petroleum usage and its associated impacts in the US transportation system.
The Program encompasses all fuel and technology options including biodiesel, natural gas, propane, electric, ethanol, and hybrids. It also includes idle-reduction and fuel economy strategies such as car share, vanpooling, truck stop electrification as well as non-automotive forms of transportation such as bicycles and scooters. The applicant fleets that receive certification can promote their fleet’s greening efforts and include the certification status in their sustainability portfolio information.
