In the initiative Sustainability4U, four universities in Graz—Med Uni Graz, Uni Graz, Kunstuni Graz and TU Graz—have formed an alliance on the topic of sustainability. In this sense, a strategic advising, development and action committee was established in order to act on (and react to) internal, interuniversity, regional, national and global challenges and opportunities based on environmental, economic, social and institutional principles of sustainable development. Examples of actions include the working out of a joint mobility concept and the establishing of a lecture series in which recognized experts from all four universities and renowned external lecturers examine current topics from a variety of perspectives.
