This blog presents insights from designing and facilitating spaces for dialogue and reflection at UN Climate Conferences. Drawing on experiences from the Co-Creative Reflection and Dialogue Spaces (CCRDS) hosted at COPs, the authors show how relationship-building, embodied practices, and reflexive facilitation can foster trust, mutual learning, and constructive exchange across diverse stakeholder groups. The article offers practical lessons on transdisciplinary process knowledge and highlights the importance of relational and facilitative approaches for collaboration in politically contested and high-pressure settings.
