i just picked up McDonough and Braungart's book Cradle to Cradle and noticed in the back that chi-town is listed as one of their partners. This is McDonough's overview of the partnership. It's a little lacking on details, but as far as I know Chicago is the only city that has seriously considered Cradle to Cradle for city renovation.

also, the book is freaking awesome from a fetishist's perspective. it smells like no other book i have ever smelled and it is almost infinitely eraseable. i underlined a bunch of stuff on one page with a fine pen, took a wet washcloth, and successfully scrubbed off all the marks and underlinings without damage to either 'paper' or ink. pretty pretty cool...
