BENTONVILLE, Ark. (AP) -- Wal-Mart Stores Inc. has increased the efficiency of its trucking fleet more than 25 percent since beginning a companywide environmental campaign in 2005, the giant retailer announced Monday.
The company said in a news release that it cut its trucks' energy use by using new technologies, improving its delivery routes and loading its trailers more efficiently.
Bentonville-based Wal-Mart said it will test new technologies and fuels for its trucks this year to improve on those advances and to reach the company's goal of doubling the fleet's efficiency by 2015.
The company said it has engaged Arvin Meritor, Peterbilt, Eaton Corporation, International and others to develop new technologies.
This year, the company said, it plans to test several vehicles: diesel-electric hybrids from Arvin Meritor and Peterbilt, Peterbilt trucks that run on liquefied natural gas and trucks that will run on waste cooking grease from Wal-Mart stores or a biofuel blend.
