Nadia Raphael Rathje has worked with education for sustainable development for many years. She was a co-founder and principal at Den Grønne Friskole in Copenhagen, a school built on the ambition to develop pedagogical and didactic approaches that support the green transition. Today, she is a researcher in the field and has completed a PhD on green school development, with a particular focus on whole-school approaches. This approach emphasizes collaboration both within and beyond the educational institution, enabling students to gain hands-on experience and a deeper understanding of sustainability.
