I came across this through a podcast (Sustainable Business Practices #021) I just listened to. It's interesting in regard to the process someone went through in getting a vision and taking the steps to implement that vision in a corporation. The guy speaking is the CEO of a carpet company and he seems to have accidentally become a sustainable/green business person because their customers began asking "what are you doing for the environment". I suppose this also illustrates the power of asking companies to provide what you want. Some of them will actually listen.
