Dry Cleaning and Home Laundry

I have been inspired by the UNEP YouTube Eco-tips for Jeans TV Spot.  "http://youtube.com/watch?v=vYprgHH7Zrw"http://youtube.com/watch?v=vYprgHH7Z rw
I am instigating a local sustainability behaviour-change program around: washing less often, washing with less environmental impact, buying garments made with non-dry clean only fabrics, green dry cleaners. It would be fantastic to know if anyone has: - Undertaken an environmental impact assessment on dry cleaning and home laundry. - Constructed a framework for sustainable behavioural approach to residential laundry practices - Experienced effective or ineffective behaviour change approaches that I should consider or discount I was thinking door knocking with information and questionnaire with follow up questionnaire 2 weeks later - Evaluated similar programs, so that I can design my program with the evaluation methodology in mind. I anticipate I will trial my approach on one street each in two suburbs.

Thanks a bucket!
