The Sustainable Development Goals (SDGs) of the United Nations that came into effect in January 2016, are the most important goals that the world should work on for the future. These goals are the successor of the Millennium Goals. In the Sustainable Development Goals, the promotion of just, peaceful and inclusive societies was included a an essential goal for the future for the first time. This is SDG16. It is a goal that matches the ideal with which the Peace Palace was founded well! The Carnegie Foundation – Peace Palace signed the SDG Charter in September 2017. A year later, on 24 September 2018, the Peace Palace was appointed by the Ministry of Foreign Affairs of The Netherlands as official ‘SDG 16 House’, the first of its kind in the world.
