“In a report released on January 28, 2010, Green Investing 2010: Policy Mechanisms to Bridge the Financing Gap, the World Economic Forum revealed that investment in clean energy has held up better than expected during the financial crisis and resulting recession, but a considerable gap still exists between current levels of investment and what is needed to begin reducing the world’s carbon emissions. The report’s authors, Anuradha Gurung and Max von Bismarck from the World Economic Forum, and Chris Greenwood and Michael Liebreich from Bloomberg New Energy Finance, state that “as a result of the continued financing gap, there is an urgent need for policy-makers around the world to implement measures at the regional, national and sub-national level, which will encourage investment in clean energy technology and projects. With this in mind, the report provides policy-makers with a toolkit consisting of 35 different policy mechanisms, which can be used to promote various clean energy sectors. The mechanisms can be chosen based on stage of technological development – R&D/proof of concept, demonstration and scale-up, commercial roll-out, diffusion and maturity – and also on stage of economic development.”
