Going Green in Procurement

I read an interesting article by Tom Jowitt at TechWorld titled Companies fail to go green on procurement. The sad part is that according to his article only 3 percent of companies in the UK are using a non-paper based procurement system. Which leads me to wonder what the statistics might look like in the U.S.? Unfortunately I did not find a lot of data in this area which leads me to believe that if only 3% in the UK that the numbers in the U.S. are probably not much higher. What interested me even more was the statistics related to Printers, Faxes, and other equipment required to produce a paper copy that ultimately produces Carbon Output. not to mention the money saved in electricty alone.
