GLOBE-Net (October 16, 2009) What is the role of investors in creating a more sustainable economy? A survey of fund managers just published by the UK’s Fair Pensions campaign provides challenging reading for anyone who believes that a green future will emerge simply through market forces operating in the investment community. The market purist argument is that the system should regulate itself; because if climate change really is a material risk for businesses, it should be built into the way companies are valued. Companies whose factories or plantations could be destroyed by climate change-induced floods or droughts should be less attractive investments than ones making wind turbines or hybrid car engines.
