Sustainability is perhaps the most important societal guiding principle of our time. Across the globe, sustainable development processes occupy first place on the agenda. In 2015, the United Nations adopted the 17 UN Sustainable Development Goals (SDGs) - an important milestone in sustainability policy. The Fraunhofer IST has also anchored sustainability in its mission statement. For the work at the institute, objectives 3, 6, 7, 9 and 12 are particularly relevant; in this context, selected activities at the Fraunhofer IST are presented below. Furthermore, projects and developments are constantly being addressed at the institute which support further or other goals.
