From  27.09. to 29.09.2023, the Green Office participated in the theme week "We need to talk! Sustainable Science" of the DG HochN in Hannover. The focus on all three days was on the dialogue between the different university stakeholders. Professors, sustainability officers, students and administrative staff reflected together on their understanding of the university system. Through the various hubs and discussion formats, it was possible to gain a broader view of various organizational dynamics and one's own position within the university.
