Austrian’s second largest city Graz has about 250,000 inhabitants including 40,000 students who are educated at four universities. “Sustainability4U” is a joint initiative of these four universities established in 2009. It tries to bundle the efforts of each university in the field of sustainable development to increase their outcomes. Through linking together the different fields of research and education (University of Graz, University of Technology Graz, Medical University Graz, University of Music and Performing Arts Graz) a holistic approach is guaranteed. A team of three persons per university meets regularly at a voluntarily basis to create new projects and adapt existing ones that aim towards both students and society. In this respect the initiative fosters interdisciplinary and inter-universitary collaboration as well as it communicates a sustainable message to people.
