The COPERNICUS Alliance (CA) aims to enable European higher education institutions and their partners to jointly identify challenges in higher education for sustainable development (HESD) and spearhead development of processes, tools, and knowledge to address these challenges from a whole-institution perspective. The CA provides a platform and organizes events where its current and future members can share resources and co-develop innovative education for sustainable development initiatives. It provides Micro Funds for members’ networking efforts and supports joint HESD proposals through advice and alliances. The CA also promotes engagement with policy-makers and community stakeholders at the European and global levels and regularly celebrates members’ ambassador activities. The CA resolutely commits to reducing the ecological footprint of its activities.
