In “Defining Sustainable Products (A),” we examine Walmart’s search for a systemic solution to define a sustainable product precisely. In this case, Matt Kistler, who succeeded Andy Ruben as the company sustainability leader in 2007, knows that the company is lagging behind on its espoused goal of selling sustainable products. The case asks students step into Kistler’s shoes as he leads Walmart’s sustainability office through a systematic review of the different models and frameworks available for measuring the sustainability of products presently in use. Eventually, the students face a decision about what Walmart should do to make systemic progress with regard to measuring and selling sustainable products. In “Defining Sustainable Products (B),” we examine the situation three years later, as Walmart assesses the progress made in achieving its goal of selling sustainable products.
