Policymakers Must Back Sustainable Development

Funding sustainable development involves big numbers. Financing shortfalls to implement UN-backed Sustainable Development Goals in developing countries amount to US$ 2.5 trillion each year. Most estimates suggest the need for US$ 6 trillion a year in infrastructure investment, much of which needs to be greened. More broadly, there is a need to align the projected US$ 20 to 25 trillion in annual investments globally on sustainable development.
