ADM Capital partner, Chris Botsford, writes in a letter to the Financial Times that more action is needed to promote sustainable development. He suggests that we all should write to our pension funds to ask how they are investing our retirement funds. We need to make sure those funds are not invested in companies that are damaging our environment. He also suggests that development banks could do more to facilitate private sector investment in development and environmental protection. Finally, Botsford suggests that finance ministers could provide tax advantages to encourage impact-type investment.
