On August 1, 2025. EKA joined ESSS as a Regular Member. ESSSR (https://esssr.eu/) is an inter-university consortium composed by members which share an interest on sustainability science and on matters related to sustainable development. It is a key organization, filling in a gap in respect of the coordination of sustainability science teaching and research at European universities seen today. 

The members benefit from a research infrastructure dedicated to advancing sustainability research in Europe. With over 80 members, ESSSR is the largest network on sustainability research in Europe. Since it was set-up in 2019, ESSSR has successfully secured a wide range of research projects, whose volume is in excess of Euro 20 million. Also, ESSSR members, together with members of its international twin, the Inter-University Sustainable Development Research Programme (IUSDRP), have published over 60 papers in high-calibre journals.
