The UCLG Culture Summit is the main meeting point at global level of cities, local governments and other stakeholders that are committed to the effective implementation of policies and programmes on culture and sustainability. The summit is a forum for knowledge-sharing, peer-learning and networking among cities and local governments. Its aim is to show that cities are leading the way in recognizing the absolute necessity of cultural factors as a key dimension of sustainable development. This is why the third UCLG Culture Summit will be called "Culture in Sustainable Development. Cities Lead".
