Ray Anderson just released his new book, Confessions of a Radical Industrialist: Profits, People, Purpose - Doing Business by Respecting the Earth. I haven't started it yet, but I have a copy and can't wait to dig in.
In the meantime the stats since they've embarked on this journey speak for themselves, these come from a recent interview with Gallup Management Journal:
"Between 1996 and 2008, Interface cut its net greenhouse gas emissions by 71% in absolute tons (the Kyoto Protocol, in contrast, called for 7% reductions by 2012, which many said was impossible). Yet over the same time frame, Interface increased sales by 66% and doubled its earnings, expanding its profit margins and propelling innovation. Interface also reduced greenhouse gas intensity (relative to sales) by 82%, wastewater stream by 72%, landfill-bound scrap waste by 78%, total energy usage by 44%, smokestacks by 33%, and effluent pipes by 71%. Interface also reached the top of GlobeScan's Survey of Sustainability Experts -- all while saving the company $405 million. And, since 2003, Interface has sold 83 million square yards of carpet with zero net global warming effect."
These kinds of success stories show what is possible with leadership, dedication, and strong sense of purpose.
