This will include integration of clear environmental goals into investment policies through a mix of policies and instruments ranging from carbon pricing, research and development (R&D), financial, and regulatory policies to “soft” measures such as education and information (OECD 2012b, forthcoming). Another priority use may be transitional support for immature technologies that is performance based and time-bound (i.e. with sunset clauses) (Kalamova, Kaminker and Johnstone, 2011). Enabling actions to foster wider industry and public support for low-carbon energy systems include: fostering industry leadership, developing a skilled low-carbon energy workforce, deepening public engagement and strengthening international collaboration. The transition offers significant new opportunities for business, as a large range of green technologies will need to be developed and deployed widely over the next few decades.
