Pulitzer-prize winning author Ed Humes starts with skepticism, asks tough questions, and ends up delivering good news. Wal-Mart embraced an unprecedented green makeover, leveraging the power of 200 million weekly customers to reduce waste, toxics, and carbon emissions. Neither an act of charity nor an empty greenwash, Wal-Mart's move reflects a simple philosophy: that the most sustainable, clean, energy-efficient, and waste-free company will beat its competitors every time.
EDWARD HUMES received the Pulitzer Prize for his journalism and numerous awards for his books. He's written for The New York Times, the Los Angeles Times, and Esquire. His books include Monkey Girl, Mississippi Mud, Garbology, Eco Barons, and Force of Nature.
