...around the world, shoppers flock to Wal-Mart to buy everything from socks to sofa beds. In McKinney, Texas, they come for another reason: to see the wind turbine. Rising 120 ft. above the ground, it's the tallest structure in town and supplies 5% of the store's electricity. It's not the only thing that makes this Wal-Mart a green giant. There are photovoltaic shingles on the roof, exterior walls coated with heat-reflective paint and a high-tech system that automatically dims or raises the lights depending on whether it's sunny or overcast. Brent Allen...
...laws of unintended consequences can be cruel for companies trying to do the right thing. The laws of economics suggest that Wal-Mart is so big, with 5,200 stores worldwide, that it influences everything from the price of lumber to the size of the container your laundry detergent comes in. And if this retailing giant throws its weight behind environmental responsibility, the impact could be profound: less air pollution at factories in China, mass-market sales of organic products, cereal boxes that aren't half filled with air. "One little change in product packaging could save 1,500 trees...
Scott wants Wal-Mart to do its part too. He has promised to cut greenhouse-gas emissions at existing stores 20% over the next few years and pledged to construct new stores that are 25% to 30% more efficient. He wants Wal-Mart's fleet of more than 7,000 trucks to get twice as many miles per gallon by 2015. Factories that show Wal-Mart they're cutting air pollution--even those in China--will get preferential treatment in the supply chain. Wal-Mart says it's working with consumer-product manufacturers to trim their packaging and will reward...
Cynics might call it a "greenwash," a bid to deflect attention from Wal-Mart's controversial labor and health-insurance practices. But it's not just window dressing, because Wal-Mart sees profit in going green. "We are not being altruistic," says Scott. "This is a business philosophy, not a social philosophy." Some top environmentalists seem convinced he's serious, including Amory Lovins, head of the Rocky Mountain Institute, who is a paid adviser. "We don't go where we don't think there's a genuine interest in change," says Lovins...
There's no question that soaring energy costs are fueling Wal-Mart's conservation drive. The company now insists that truckers shut off their engines when stopping for a break, yielding estimated savings of $25 million a year. By doubling the gas mileage of the fleet through better aerodynamics and lower-friction tires, Wal-Mart expects to pocket $310 million a year. One of the biggest items on its energy bill is lighting. Instead of going with the cheapest bulbs, the company is experimenting with costlier LED strips for refrigeration units that last longer and use less energy. Scott also...
