This article describes a global governance system that—from the author’s point of view—would lead to sustainability and allow the implementation of the Sustainable Development Goals (SDGs), which have just been adopted at the UN level. Major elements are (1) the integration of existing international regimes in the area of the UN, WTO and the world financial system into an integrated “Global Governance Body”. (2) This institution would, among other functions, be responsible for the major global commons and put a fee on their usage with two aims: (i) to protect them and (ii) to generate money for financing global development and the SDGs. (3) To monitor the income and property distribution by politics with the political mandate, to keep it in the so-called “efficient inequality range”. This may need international co-financing. (4) It will, if done properly, prevent two-class societies, it will furthermore allow the building-up of social systems everywhere in the world with the aim to have a reasonable balance of wealth in all states, and also between states. (5) It will also be of help if artificial intelligence systems took over hundreds of millions of jobs for highly qualified people in the next decade. (6) This global institution would also be able to pay in defense of cultural diversity and for the protection of the environment, e.g. rainforests. (7) This would also allow us to do what is needed for avoiding uncontrolled climate change, e.g. improve the recent Paris accord concerning climate.
