United Parcel Service (UPS) and the Houston-Galveston Area Council’s (H-GAC) Clean Cities/Clean Vehicles program announced on December 11 that they have teamed up to reduce vehicle emissions. UPS has purchased 68 large, low-emission tractor trailers for its Houston-Galveston fleet through supplemental funding from the Clean Cities/Clean Vehicles program. The state-of-the-art vehicles will reduce NOx emissions released to the atmosphere by approximately 48 tons annually. The supplemental funding allowed UPS to replace a like number of big tractor rigs with environmentally friendly alternatives even though the original tractors weren’t old enough for retirement. The new vehicles join UPS’s nationwide fleet of more than 1,437 low-emission vehicles and 1,800 alternative-fuel vehicles.
