MIT Professor Yossi Sheffi has just published, along with Edgar Blanco of Amazon, the definitive book on sustainability in business. For supply chain enthusiasts like me the topic is endlessly complex and compelling, but arguably too big to pin down systematically. This new book, Balancing Green, does it. It is deep and technically credible, but also readable and loaded with familiar names and stories. Most importantly, it tackles the question of sustainability without a preconceived agenda.
