UPS Adds 306 CNG and LPG Vehicles to Delivery Fleet

UPS is adding 306 alternative fuel vehicles to its fleet by placing an order for 167 Compressed Natural Gas (CNG) delivery trucks while taking delivery of 139 new Liquefied Petroleum Gas (LPG, or propane) delivery trucks in North America. Additionally, the company has launched an initiative to use biodiesel fuel in its ground support vehicles at the UPS air hub in Louisville.

UPS’ global alternative-fuel fleet now stands at 1,629 vehicles—the largest such private fleet in the transportation industry—and includes CNG, liquefied natural gas, propane and electric and hybrid electric vehicles. The company also is working with the Environmental Protection Agency on a hydraulic hybrid delivery vehicle.

While there’s a great deal of interest in the research we’re doing with new types of hybrids, 70 years of testing alternative fuel vehicles has taught us there are multiple technologies that can effectively reduce our dependence on fossil fuels as well as our carbon footprint. Adding this many propane and CNG vehicles is going to have a very positive impact.

—Robert Hall, UPS’s director of vehicle engineering

The CNG trucks will be deployed early next year in Dallas, Texas; Atlanta, Georgia; and four California cities:  Los Angeles, Ontario, San Ramon and Fresno. They will join more than 800 such vehicles already in use in the United States. The propane vehicles are joining nearly 600 propane trucks already operating in Canada and Mexico.

The propane and CNG trucks currently in the UPS fleet were converted from gasoline and diesel vehicles in the 1980s to run on alternative fuels. The new trucks are originally manufactured for alternative fuel use.

UPS is purchasing the chassis for the CNG trucks in two sizes from Freightliner Custom Chassis Corporation. The trucks will feature engines from Cummins Westport that are expected to yield a 20% emissions reduction and 10% improvement in fuel economy over the cleanest diesel engines available in the market today. The truck bodies will be identical externally to the signature-brown trucks that now constitute the UPS fleet and will be marked as CNG vehicles.

The new propane-powered vehicles were manufactured by Workhorse Custom Chassis and feature the latest technology in clean-burning propane engines provided by Baytech Corporation. Propane vehicles emit about one-third fewer reactive organic gases than gasoline-fueled vehicles. Nitrogen oxide and carbon monoxide emissions also are 20% and 60% less, respectively, than conventional vehicles.

The UPS propane vehicles will run on liquefied petroleum gas (LPG) provided at eight on-site fueling stations at UPS facilities in Canada. LPG is derived from petroleum during oil or natural gas processing.

The biodiesel initiative in Louisville is being launched with the support of a $515,000 federal grant that is helping offset some of the cost of building a fuel infrastructure at the airport. The infrastructure will provide a B5 biodiesel blend of fuel to run 366 ground support vehicles starting early next year.

While continuing to develop its alternative fuel fleet—UPS already has invested more than $15 million in the effort—the company also has purchased and is operating nearly 20,000 low-emission conventional vehicles.



This is good. The last time I saw a fleet of UPS trucks taking off for the morning, they were spewing a huge trail of diesel smoke behind each of them.


This is excellent. A small step in the right direction. My question would be how much more does it cost to convert these trucks to natural gas and biofuels? What is the cost-per-mile comparison with diesels and gas? What other emissions should we be concerned with using CNG? Im glad to see UPS taking the lead.
