We are expected to support society in solving urgent problems in such a way that even our grandchildren will still approve of the decisions we make today. Sustainability is therefore of central importance to Forschungszentrum Jülich. In this Sustainability Report we outline how we envision performing our work in a sustainable manner on our large and mostly self-contained campus, a real “research town”. The Report, which is based on the guidelines of the Global Reporting Initiative (GRI), is a further core component of the activities to realize a sustainable campus. The report will document the economic, environmental, and social performance of Forschungszentrum Jülich and enable it to be compared and reviewed, so that our partners, employees, and policy-makers can understand and take part in the process of change. At the same time, the report will help to define sustainability goals.
