Green technologies should be treated as infant industries, with appropriate support, including public sector investments in infrastructure, subsidies and access to credit (Ocampo, 201 lb). Policies should also be designed to encourage interaction and knowledge-sharing among domestic and international firms, research institutes, universities, policymakers and other actors. Other policy suggestions based on a green systemic approach could encompass innovative sources of equity-linked financing and long-horizon green country funds. The G-NIS approach emphasizes that policymakers do indeed need to make choices on how to best support innovation, and suggests a framework for government decisionmaking and investment.
