Together with colleagues from the University of Hamburg, Christian Fieberg has been working on behalf of the United Nations Department of Economic and Social Affairs (UN DESA) over the last few months on the concept of a world equity index that makes the 17 SDG's investable. The concept will serve as the investment basis for the Global Investors for Sustainable Development (GISD) Alliance.

The UN reports on the result of the joint work here:
