Company surpasses goal of 25 percent fleet efficiency gain in three years

BENTONVILLE, Ark., Feb. 2 /PRNewswire-FirstCall/ -- Today, Wal-Mart Stores, Inc. announced it will test two new types of heavy-duty commercial hybrid trucks and two different alternatively fueled heavy duty trucks as a part of the company's efforts to build on its progress in developing a more sustainable trucking fleet. The new trucks include:

    --  A full-propulsion Arvin Meritor hybrid that will initially operate in
        the Detroit area. This dual-mode diesel-electric hybrid is believed to
        be the first vehicle of its type;
    --  Fifteen trucks operating in Buckeye, Ariz. distribution center near
        Phoenix, will be converted by Environmental Development Group to run on
        Reclaimed Grease Fuel(TM), made with the waste brown cooking grease from
        Walmart stores. In addition, the remaining trucks located in the Buckeye
        distribution center will operate on an 80/20 blend of biodiesel made of
        reclaimed yellow waste grease;
    --  Five Peterbilt Model 386 heavy duty hybrid trucks with diesel-electric
        hybrid power systems developed by Eaton Corporation and PACCAR, that
        will be based in Dallas, Houston, Apple Valley, Calif., Atlanta and the
        Washington/Baltimore regions and;
    --  Four Peterbilt Model 386 trucks and one yard truck, which operates only
        on the distribution center property, will operate on liquid natural gas.
        These trucks are part of a partnership with the Mojave Air Quality
        Management District and will operate out of the distribution center in
        Southern California.

"In order to meet our goal of doubling our fleet efficiency, we are taking an active role in the development of these technologies," said Chris Sultemeier, senior vice president of transportation for Wal-Mart Stores, Inc. "We look forward to determining if these technologies will help reduce our environmental footprint, are viable for our business and provide a return on investment."

Wal-Mart achieved more than a 25 percent increase in efficiency within its private fleet between 2005 and 2008, surpassing one of the company's stated sustainability goals. By reaching this goal, Wal-Mart has been able to reduce its carbon dioxide emissions and its fuel use. This goal was reached by using a combination of new, innovative technologies, better delivery routes and by loading its trailers more efficiently. Now, the company is working toward its goal of doubling its fleet efficiency by 2015, from its 2005 baseline. Part of this pilot program is to determine if alternatively fueled trucks can help move Wal-Mart toward that goal in addition to reducing environmental impacts.

Wal-Mart has actively engaged several suppliers to develop and test these new technologies. This includes Arvin Meritor, Eaton, Peterbilt and International as well as smaller companies. Wal-Mart will test these new technologies throughout 2009.
