The project aims to empower young people and youth workers to shape inclusive, greener and fairer cities by linking youth-led placemaking with climate action. Objectives are: O1 co-create participatory methodologies; O2 strengthen agency and competences of youth and youth workers (through local co-creation & an international Training Course); O3 produce accessible digital outputs (Hybrid Youth Action Roadmap, Youth Action Playbooks); O4 foster recognition and policy uptake of youth work.
