UPS said it will invest more than $90 million in natural gas facilities and vehicles, including fueling stations, compressed natural gas trucks, and liquefied natural gas vehicles.

The company plans to build an additional six CNG fueling stations and add 30 new CNG tractors and terminal trucks as well as 50 LNG vehicles to its alternative fuel and advanced technology fleet.

“With more than 4,400 natural gas vehicles and a network of fueling stations, UPS has had great results using natural gas as an alternative fuel in our fleet,” said Mark Wallace, UPS senior vice president of global engineering and sustainability. “We know the importance of investing in natural gas globally for our fleet and the alternative fuel market. In 2016, we used more than 61 million gallons of natural gas in our ground fleet, which included 4.6 million gallons of renewable natural gas. This helped us to avoid the use of conventional gas and diesel, and decreased CO2 emissions by 100,000 metric tons.”

Last year, UPS invested $100 million in CNG fueling stations and vehicles. The company currently operates 31 CNG fueling stations in Alabama, Arizona, California, Colorado, Georgia, Kansas, Kentucky, Louisiana, Nevada, Oklahoma, Pennsylvania, Texas, Virginia, Tennessee and West Virginia. It runs CNG vehicles in 38 states in addition to ones in Germany, the Netherlands, and Thailand.

The six new CNG stations will be built in Ontario, California; Orlando, Florida; Salina, Kansas; Louisville, Kentucky; Greensboro, North Carolina, and Vancouver, British Columbia, Canada. Renewable natural gas will be used at the station in Ontario. UPS also purchased 50 additional LNG vehicles that were deployed in Indianapolis, Indiana; Chicago; Earth City, Missouri; and Nashville, Tennessee, where UPS has existing LNG stations.

Since 2009, UPS has invested more than $750 million in alternative fuel and advanced technology vehicles and fueling stations globally. The company has driven over a billion miles since 2000 with the alternative fuel and advanced technology vehicles, which include natural gas, electric, hybrid and other types of powertrains.
