I normally lose interest in any business-oriented book about 5 pages in (if I read one at all, really). While this one flagged a bit in the middle, the ideas were compelling and inspiring throughout. Obviously sustainability is on everybody's mind these days. But Werbach has really walked the walk throughout his career as activist and business consultant, and so I take his assertions much more seriously than some of the Johnny-come-latelys also touting this green gospel. The book also wouldn't be as successful if Werbach wasn't armed with a plethora of case studies and practical solutions to the larger problems he lays out. Probably required reading for anyone running (or consulting with) a business today.
