New knowledge, created in international cooperation, is essential for global sustainability. Set against this background, this study focuses on German science policy for research cooperation with developing countries and emerging economies in sustainability research. Based on interviews with policy makers and researchers, the book scrutinizes the actors, processes and contents of science policy in Germany. The author argues that science policy mainly aims at German economic benefits and technology development. This, however, negatively influences global sustainability. To counter existing path dependencies, the author provides recommendations for sustainability-oriented scientific practice and science policy.
