market that could potentially wield substantial influence on industry. The Home Greenup project entailed thousands of home visits a year. The recommendations of the inspectors were accompanied by a list of certified green contractors for various kinds of building retrofit and renovationwho would derive substantial business from the recommendations. But through the products directory, the audits might translate into big sales for manufacturers of listed building products. And such a guaranteed market might give the community power to request the (local/regional) production of particularly desirable itemsa no-VOC paint, a non-PVC weatherstripping, etc. Murray and Collins also hatched an arrangement with local credit unions to issue special discount cards (called eco-cards) along with directories, which would enable card-holders to obtain discounts on listed products and services. The cards would be smart cards whose swiping would record important information on green purchasing patterns, which would be another enticement for manufacturers, and another bargaining chip for the community in influencing their own economic development. This combination of an information infrastructure, consumer cooperation and green enterprise would constitute a powerful complex of community development. Once established, the possibilities for generating other developmental connections would have been endless. Besides building materials, the directory also included sections on food, appliances, heating equipment, sustainable transportation, and recycling providing opportunities to dovetail projects with a range of Ontario environmental and c.e.d. groups. In the realm of building materials, however, plans were already being made to influence mainstream materials retailing in Toronto. As the first draft of the directory was being completed, local building material retailers were approached about
