Stuart L. Hart is one of the world's top authorities on the implications of sustainable development and environmentalism for business strategy. He is currently SC Johnson Chair of Sustainable Global Enterprise and Professor of Management at Cornell's Johnson Graduate School of Management. Previously, he taught strategic management and founded both the Center for Sustainable Enterprise (CSE) at the University of North Carolina's Kenan-Flagler Business School, and the Corporate Environmental Management Program (CEMP) at the University of Michigan. His consulting clients range from DuPont and Hewlett-Packard to Procter & Gamble and Shell. He wrote the seminal article "Beyond Greening: Strategies for a Sustainable World," which won the McKinsey Award for Best Article in Harvard Business Review in 1997, and helped launch the movement for corporate sustainability. With C.K. Prahalad, Hart also wrote the pathbreaking 2002 article "The Fortune at the Bottom of the Pyramid," which provided the first articulation of how business could profitably serve the needs of the four billion poor in the developing world.
