As part of a GreenBiz webcast, Arizona State University Senior Sustainability Scientist George Basile and Dell's director of global sustainability operations Bruno Sarda shared their advice on what it takes to tackle sustainability challenges: sustainability leaders. "One of the big challenges is that sustainability is typically framed as a set of disparate problems," Basile says. "It doesn't allow business leaders to be effective." A sustainability leader needs to inspire and transform businesses and organizations if improvements are to be made. Sarda shares his six steps for implementing sustainability at Dell: vision, strategy, goals, plans, execution, and communication. Fortunately, both experts agree sustainability leadership can be learned.
