ICLEI World Congress showcases how cities, towns and regions across our network are advancing sustainable urban development worldwide.
From the founding World Congress in New York City, USA in 1990, the ICLEI World Congress has always taken a deep and critical look at the most relevant and pressing issues in urban sustainability. The ICLEI World Congress is the core event organised by ICLEI. Each event is a chance for the network and our partners to come together and outline the future of sustainability in urban areas worldwide.
