A particularly interesting initiative in this regard is a grassroots effort based in Portland Oregon called the Sustainable Products Purchasers Coalition (SPPC). It combines expertise in LCA with grassroots membership. Besides helping to develop consistent standards for LCA studies and encouraging firms to engage in LCA, it tries to demonstrate to producers, through its membership, that there is a substantial market for products that meet the Coalitions life-cycle standards (Sustainable Products Purchasers Coalition (SPPC), 2002). It provides one of the best examples of the power of information (combined with vision and community organization) to create market power that in turn transforms production. I will return to this topic and discuss SPPC more thoroughly in Chapter VI.
