To measure how its eco-friendly products are faring with consumers, Wal-Mart launched the Wal-Mart Sustainability Live Better Index in 2007. This index allows Wal-Mart to track, on a state-by-state basis, consumers’ demand for low-cost products, health and welfare products, and green products. In the sustainability category, consumers can track adoption rates at Wal-Mart in the following categories: compact florescent light bulbs, organic milk, extended-life paper products, organic baby food, organic cleaning products, and organic coffee. Wal-Mart believes that consumers can “make a conscious decision to purchase them for their environmentally friendly and cost-saving benefits versus conventional versions.” So far results have been good, with a 66 percent increase in average adoption rates.
