Maastricht Sustainability Institute is Maastricht University’s scientific institute for sustainable development. As sustainability scientists, we aim to support sustainable development at the local and regional levels, thus contributing to global sustainability too. Because sustainability challenges are complex and normative, we opt for interdisciplinary and transdisciplinary approaches in which we collaborate with different disciplines and stakeholders. We master a diversity of theories and methods to work at the interface of science, policy and society. Knowledge brokering, boundary work and action-research are concepts that suit us well. Our research is scientifically sound and societally relevant. Furthermore, our expertise is reflected in our sustainability education at bachelor, master and PhD level. Our multidisciplinary staff and international student group form a close-knit learning community. In addition to our international and national orientation, we are committed to addressing sustainability issues in the region by means of our Maastricht Sustainability Hub.
