This document discusses how companies can pursue a "Green Ocean" competitive strategy through sustainability initiatives. It provides two examples - office furniture company Herman Miller and car rental company Enterprise. Both companies set ambitious sustainability goals that differentiated their products and brands in the market. Herman Miller committed to zero waste and 100% green energy by 2020. Enterprise launched a large fleet of hybrid vehicles, sustainable construction practices, and invested $100 million in algae biofuels. Pursuing a Green Ocean strategy through outrageous sustainability goals can help companies create uncontested market space and make competitors irrelevant.
