What does the often unclear term “sustainability” mean? How can life and economy be sustainable? This will be the subject of the Colloquium Fundamentale entitled “Nachhaltig – aber wie? Vom Schlagwort zu nachhaltigen Entwicklungen" (Sustainable – but how? From the catchword to sustainable developments) organized by ZAK | Center for Applied Cultural Science and Studium Generale at Karlsruhe Institute of Technology (KIT) in the next two semesters. The series of events in the Science Year “Project Earth: Our Future” will start on Thursday, April 26, 2012, 18.30 hrs, with a presentation by the expert on international law Professor Eibe Riedel on sustainability and human rights.
