The Green Erasmus Educational Framework is a guidebook that serves as a guideline intended for teaching staff, staff responsible for curricula design, and other relevant personnel in Higher Education Institutions who have the responsibility to integrate Education for Sustainable Development (ESD) in their Institutions. The Green Erasmus project strived to improve the environmental sustainability of the Erasmus+ Programme and raise awareness across the European Higher Education sector about the importance of sustainable internationalisation. The project focused on developing an Educational Portal on Sustainable Internationalisation and carrying out comprehensive analysis of the environmental impact of Erasmus mobilities.
