Humes (Eco Barons: The Dreamers, Schemers, and Millionaires Who Are Saving Our Planet) expertly explains the working relationship between Wal-Mart CEO Lee Scott and Blu Skye sustainability consultant Jib Ellison, who are working to redefine Wal-Mart as a green company, and how going green raised its bottom line. Because of its size and retail dominance, Wal-Mart has tremendous influence on suppliers, partners, competitors, and the global economy. Surprisingly, the retail chain has entered areas such as carbon emission reduction, water conservation, and renewable energy. Strides have been made in the growing of organic cotton, efficient supply chains, and packaging. The book gives clear-cut examples and discusses changes needed in the organizational culture to embrace environmental corporate responsibility. VERDICT This book will appeal to readers across income, age, and lifestyle brackets, because it discusses a topic that impacts the public. Recommended for all public and academic collections.—Caroline Geck, MLS, Newark, NJ
