“Sustainability4U” is a joint initiative of the four universities in Graz (University of Graz, Medical University, University of Music and Performing Arts and University of Technology) 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, a holistic approach is guaranteed. A team of representatives from each 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-university collaboration, and it communicates a sustainable message to people.
