Actors of Urban Change is a European network organization dedicated to sustainable urban development. The program emphasizes co-creation as a key strategy for driving positive change in cities by connecting diverse stakeholders from the nonprofit, public, and private sectors. Over a period of 18 months, selected teams of three members collaborate on urban challenges, receiving financial support, training, and opportunities for international networking. The program includes four international meetings where participants can share insights on project management, citizen participation, and advocacy. The initiative aims to inspire lasting change by fostering collaboration across different sectors, addressing critical issues like climate change, social inclusion, and urban infrastructure to create more sustainable and equitable cities.
