This is an insightful, provocative, and terrifically readable book, which provides a window onto the environmental and social challenges faced by both business leaders and citizens in the 21st century. It is not just a guide on how to do business responsibly in the new century, though it is surely that. In Sustainable Excellence, Cramer and Karabell intelligently consider the forces that are transforming the global landscape for the world's businesses and for the multitudes they serve. One can read the book as something of a primer for entrepreneurs on how to respond--responsibly and intelligently--to the difficult and complex challenges created by an increasingly interconnected global economy. But Sustainable Excellence does much more. In the end, this striking volume offers both guidance and insight for anyone who takes the time to read it--whether you own a business, work for one, invest in one, or merely purchase and consume what is being produced. As businesses and citizens reflect upon the promise and perils of the 21st century, this illuminating study has much to tell us about precisely what it will take to move forward in an environmentally and socially conscious way.
