The paper deals with the issue of whether a sustainable future for humankind can be reached or not. If not, human existence would not come to an end, but the quality of existence would considerably deteriorate. For many reasons, it is not easy to get onto a sustainable track. Doing so will require the equivalent of surgery on a “living body”. And many powerful vested interests are in the way. If success can at all be achieved, it will require considerable changes in global governance. The restricted quality of global governance today is a key deficit of the world we live in today. The author was often asked, what system of global governance rules for the world to implement, if one had the power to do so. The paper gives the answer to that question in the form of twelve interrelated elements of global governance for a sustainable future.
