Wal-Mart Chief Executive Lee Scott laid out ambitious environmental goals in late 2005 as the world's largest retailer sought to burnish its reputation against mounting criticism.
Nearing the two-year mark, Wal-Mart Stores Inc. is still compiling a major report on how far it has come with the program overall, including reducing waste, using more renewable energy and stocking more green products.
But one division says it is already well under way to meet its goals. Wal-Mart's fleet of about 7,200 semitrailer trucks is already about 15 percent more fuel efficient and the company knows what changes it needs to make to meet a target of 25 percent by late next year.
The annual savings in carbon dioxide, a greenhouse gas, would be equal to taking 67,744 cars off the road.
Some talk about protecting the environment, others do it.
