Wal-Mart – the Leader of Sustainability Indexing?

Wal-Mart is planning quite a “first”: it will implement a new “sustainability index,” by which it will report the environmental impact of each and every piece of merchandise available for sale. Many of the corporation’s 60,000 suppliers are up in arms, as compliance will likely require them to dig deep into their supply chains. But many proponents of sustainability are also skeptical. Will the index be yet another incomplete measurement of so-called sustainability that ultimately leads consumers astray, or worse?


The index is intended to help consumers navigate conflicting or misleading claims on merchandise, Wal-Mart’s senior director of business strategy and sustainability Rand Waddoups reportedly claimed. The index will assess items using a tool called the “Life Cycle Assessment,” which measures a product’s environmental impact in its manufacture, use, and disposal. The corporation is considering measuring products’ social impact as well, by dividing its stock into four categories: energy and greenhouse gas emissions; natural resources; materials; and “people and communities.” Wal-Mart created the index with the assistance of faculty from Harvard, Stanford, the University of California at Berkeley, and the University of Michigan.
Yet many are wary of the index. Reportedly, some faculty that helped create the index even hesitated to participate in the consortium at which the index will be revealed because of, well, Wal-Mart’s reputation. After all, who decided that Wal-Mart should be the nation’s sustainability police? And will Wal-Mart report its other sustainability measures transparently? After all, cataloging the sustainability of individual products may not be enough to make Wal-Mart as a whole sustainable….
Wal-Mart is scheduled to reveal details of the index Thursday at a consortium at its corporate headquarters in Arkansas. As for information on the index’s long-term impact, only time will tell.
