Green to Gold by Esty & Winston

I've been reading the book 'Green to Gold' for my Intro to Recycling and Resource Management class. I am impressed by the amount of research that obviously went into writing the book. Eco-Advantage, Green strategies, Green metrics, etc., etc., they have covered it all. Every topic having real business world examples of what is being discussed. I am really interested to hear about another side of many of the companies mentioned in the book, having worked with them over the years in a telecommunications service provider role. Knowing their what their businesses are and how they like to do business in that arena and now seeing them in a different light, green!
