The company takes a “rolling laboratory” approach which means it’s always testing different technologies to find the best sources of energy for its vehicles. UPS recently began a pilot program testing propane vehicles in Gainesville, Ga., and over the past year has deployed 20 biomethane vehicles in the United Kingdom. UPS also currently operates approximately 1,000 compressed natural gas (CNG) vehicles and will begin a pilot program testing CNG tractors in early 2014 as it continues to look toward natural gas as a substitute for conventional fuel.Between 2000 and the end of 2012, the UPS alternative fuel and advanced technology fleet logged 295 million miles. In 2012, the growing fleet drove 49 million miles, a 43 percent increase compared to 2011.
