The project CLIM-SUSTAIN, funded by the BMBF, aims to investigate the impacts of climate and sustainability education within the context of higher education institutions, as well as measures for behavioral change. It involves exchanging research findings and experiences, identifying best practices, and providing recommendations for adapting curricula to promote relevant knowledge and sustainability awareness among policymakers, university staff, and students. The goal is to establish a consortium of higher education institutions in Central and Southeast Europe and submit a joint research proposal for EU funding to implement collaborative initiatives in the future.
