Gang,
I taught a dynamic group of MBA students this Spring and they pushed my thinking on several issues. I just posted a blog to the ARCS site (http://www.corporate-sustainability.org) on some of our conclusions with respect to LEED certification. I'd be interested to hear what you think. If you do have a response, please register and post to the blog. See you all at ARCS 2.0 on May 12.
