In June 2024, the ICLEI network will come together for the ICLEI World Congress 2024, hosted by the City of São Paulo, Brazil. Every three years, the ICLEI World Congress showcases how local and regional governments across our network are advancing sustainable urban development worldwide.

We are running out of time to resolve existential threats such as poverty, hunger and climate change. We need courageous decisions and large-scale solutions. The Hamburg Sustainability Conference challenges barriers to SDG implementation, while steering momentum with a systemic approach to answer questions such as: How can value chains become climate-friendly and create more value in the Global South? How can the enormous potential of the private sector be unleashed to achieve the SDGs? And how can we help  today's sustainability pioneers to set tomorrow's standards?
