Anheuser-Busch InBev has laid out a five-year path to sustainability. One of the world's largest brewers, Anheuser-Busch has committed itself to an ambitious plan for slashing the use of water, energy and packaging material, as well as the emission of greenhouse gases, by 2017. In this episode, Hugh Share, senior global director of Beer Better World for Anheuser-Busch InBev, details the steps the company is taking both internally and with outside partners to keep its promise to the environment. The effort required a ''holistic approach,'' he says no easy task for a company the size of Anheuser-Busch.
