Clean Sweep, Inc. and other fleets certified as Tennessee Green Fleets for emission reductions efforts
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 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. Read more about each fleet below.
The Tennessee Green Fleets Certification Program was developed jointly by East and Middle-West Tennessee Clean Fuels, Tennessee’s two Department of Energy Clean Cities Coalitions, with the goal of recognizing the exemplary work of fleets who are working towards alternative fuels adoption and emissions reduction. 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 encompasses all fuel and technology options including biodiesel, natural gas, propane, electric, ethanol, hybrid, idle-reduction and fuel economy strategies such as car share, vanpooling, truck stop electrification, as well as non-automotive forms of transportation like bicycles and shooters. The applicant fleets that receive certification can promote their fleet’s greening efforts and include the certification status in their sustainability portfolio information.
TNGreenFleets’ five newly certified fleets prevented a combined 972.7 tons of CO2 emissions from being released into the atmosphere in 2018. That tonnage does not include the emissions reductions from the 20 fleets certified from 2016-2018.
Clean Sweep, Inc. Certified Star 1
Clean Sweep, Inc., is a stand-out example of how alternative fuels can be used in many unique applications. They run a fleet of sweeper trucks out of Chattanooga, and three of the fleet’s 10 trucks run on propane autogas (LPG). They replaced aging diesel sweepers with gasoline sweepers that were then converted to run on propane. Clean Sweep is a partner for outreach, and just finished showcasing one of their sweepers at the 2019 Southeast Diesel Collaborative meeting in that was held in September 2019 in Chattanooga. ICOM North America was their conversion partner.
2018 CO2 reduction: 6.7 tons / year

Clean Sweep began their process in 2017. This included a) replacing older diesel sweepers with new gasoline-powered sweepers, then b) having those gas-powered sweepers converted to run on propane autogas. ICOM North America was the selected converter and this photo shows ICOM staff helping Clean Sweep owner Pete Phillips decide on where they would place the propane tank on a new gas sweeper.
