Implementing a sustainability strategy requires firms to consider economic, strategic, environmental, and community perspectives. Suitable for MBA, undergraduate, and executive learners, this sustainability case covers innovation, intrapreneurship, and strategy. An Excel carbon footprint analysis exercise (UVA-ENT-0112X) accompanies the case; a technical note entitled, "Corporate Greenhouse Accounting: Carbon Footprint Analysis" (UVA-ENT-0113) is an effective complement. Frito-Lay's Arizona facility pilots a program to take its snack chip manufacturing off the grid. Decision makers discuss operating, financial, marketing, and corporate strategy as the facility calculates its carbon footprint, converts to non-fossil-fuel energy sources, and stops relying on the scarce local water supply.
