I would suggest searching sustainable indexes and such. Try starting out by searching the links for sustainability. I've read some books about it in the US, but I cannot think off the top of my head of names of books or websites, and all the resorces I have on it at the moment are german, so it would not really help you.
I would suggest reading something by McDougnel (I think that is his name) He wrote a book called from Cradel to Cradel (do not mind my spelling).

visit Ad Busters. i'm sure you'll find it interesting if you are concerned with such issues.

they sell Blackspot Sneakers. : anti-brand, environmentally friendly sneakers made in unionized factories.

i know that at my local co-op they have a listing of northwest businesses called the green papers or pages or something,
but i dont know if there is a website. or where you are located.

co-ops are good places to troll around for that sort of info though.

okay a quick search lead me to the green pages website

Cradle to Cradle: Remaking the Way We Make Things by William McDonough... it's a wornderful book! however it's more about new technologies and a new approach rather than any practical advice as to what shops to shop in...
