UPS has tapped 245 new delivery trucks powered by compressed natural gas, which will be used in cities in Colorado and California.
The new trucks are part of the company's effort to reduce emissions and lower its carbon footprint.

The new CNG trucks have been deployed to Denver and four cities in California, including San Ramon, Fresno, West Los Angeles and Ontario.

UPS began using alternative fuel vehicles in the 1930s with a fleet of electric trucks that operated in New York City. UPS operates more than 1,900 alternative fuel vehicles.

"The greening of our fleet demonstrates the effectiveness of harnessing multiple technologies and applying the right vehicles to areas where they will provide the best advantage," said Bob Stoffel, UPS senior vice president of supply chain, strategy, engineering and sustainability. "Compressed Natural Gas continues to be a sustainable technology for UPS's fleet because natural gas is cost effective, clean-burning and abundant."

The 245 trucks deployed over the past month were built from scratch as CNG vehicles. They join more than 900 CNG vehicles already in use by UPS worldwide. The trucks are built with the same bodies as the signature-brown trucks that comprise the UPS fleet. The CNG trucks are expected to yield a 15 percent emissions reduction over clean diesel engines.
