Peterbilt Motors Co of Denton reduced forklift nitrous-oxide emissions by 17% in 2009 (compared to 2008 levels) and scored other environmental achievements in gaining recognition from the non-profit North Texas Clean Air Coalition.

The manufacturer of medium- and heavy-duty trucks operates 63 liquid propane gas-powered Yale forklifts with lifting capacities of 3,000-12,000 lbs (1,350-5,400 kg).

Jim Fykes with Peterbilt says the firm replaced four forklifts "in the overall fleet and reduced NOx emissions from 6.27 (short) tons to 5.2 (short) tons annually. This number was calculated using the engine manufacturer's specifications and estimated annual service hours".

Peterbilt completed the project in 2008 in its Denton factory.

The Railroad Commission of Texas helped fund Peterbilt's purchase of the forklifts through an incentive grant under the Texas Emissions Reduction Plan targeting equipment emitting smog-producing pollutants.

"We are extremely proud to accept the employer of the year award for our environmental efforts and are committed to improving our business and manufacturing efforts with practices that provide beneficial environmental outcomes," says Bill Jackson, general manager of Peterbilt and vice president of parent firm PACCAR Inc.

Peterbilt partnered with Denton Municipal Electric to purchase renewable energy, and maintained its zero-waste-to-landfill designation status since 2008.

PACCAR of Bellevue, Washington acquired Peterbilt in 1958 and operates the business as a subsidiary. PACCAR's marketing nameplates include Peterbilt, Kenworth and DAF.

The North Texas coalition encourages voluntary efforts to improve air quality in the Dallas and Fort Worth metroplex and nearby markets through educating, engaging and recognising the business community.
