The Bonn Sustainability Portal presents knowledge about sustainability generated in Bonn, links actors in the field of sustainability and thereby highlights the potential of Bonn in this realm. The portal promotes the scientific discourse as well as the dialogue between research and politics. Bonn-based organizations post relevant events, news, comments and announcements like e.g. job and training offers. Thus, the Bonn Sustainability Portal provides at once a forum as well as a contact and information network.
