At LLIS, the teachers have set themselves the task of learning sustainability together with the students, be it in the form of projects, discussion rounds, in extracurricular places of learning and in everyday situations. Our sustainability representatives (1-2 students per class) play a special role, as they are the mouthpiece for the whole class. In this way, the idea of sustainability in LLIS has a wide reach, which is crucial for the implementation of sustainable development.
