The problem is that both the private and the public tracks appear to have ignored potentials for convergence and the opportunity costs of collaboration - or at least of communication. Neither has explored sufficiently potential value afforded by collaboration with the other. In addition, there are "disconnects" in markets for environmentally viable and sustainable products and processes. Such disconnects are between: (a) supply and demand sides, (b) private interests and public priorities; (c) global markets and local needs; (d) financial instruments and institutional mechanisms; (e) existing technologies and those on the market; (f) incentives for requirements and investments in R&D; (g) knowledge resources and mechanisms for diffusion. And the list goes on.
