On 13 December, the German Advisory Council on Global Change (Wissenschaftlicher Beirat der Bundesregierung Globale Umweltveränderungen - WBGU) presented a report entitled "Development and justice through transformation: The Four Big 'I's" to Federal Environment Minister Barbara Hendricks and Federal Research Minister Johanna Wanka. In its report, the WBGU recommends that the group of twenty major industrialised and emerging economies (G20) provide strong leadership and vigorously tackle the implementation of the Sustainable Development Goals and the Paris Agreement on climate change, both adopted in 2015. These two agreements are gaining even greater significance in view of the growing tensions and divisions both in global politics and in many national societies. This applies even more after the presidential election in the USA. Sustainable development, particularly global climate protection, is currently the only ambitious project involving all the world's nations on which a consensus could be reached. States can build mutual trust through successes in this important policy field. In this way, the Great Transformation towards sustainability also becomes a peace project.
