The Alumni Network brings together almost ten cohorts of graduates from the Master of Sustainable Development who are now working as sustainability professionals across the world. Our alumni contribute to sustainable development in diverse fields, including the public and private sectors, academia, non-governmental and humanitarian organizations, international institutions, and grassroots initiatives. Through this network, we aim to strengthen connections among graduates, current students, the programme and the CELESTE Network, creating a growing community committed to advancing sustainable development across different regions, sectors, and professional paths.
