"Was is(s)t Bonn?" is the slogan for an app-based city tour designed by students of the University of Bonn Faculty of Agriculture as part of campaign month "Fairer Februar 2023".

The University of Bonn hosted its inaugural Sustainability Day in 2022 on the Poppelsdorf campus, featuring numerous sustainability-focused organizations and initiatives presenting their work at exhibition stands. That year, and again the following year, many representatives from the Faculty of Medicine and University Hospital Bonn took part, eager to share recent developments and highlight their ongoing efforts in the field of sustainability.
