São Paulo, Brazil / Bonn, Germany (24 June 2024) – Organized by ICLEI – Local Governments for Sustainability and hosted by the City of São Paulo, the ICLEI World Congress 2024 brought together over 1,500 global urban leaders to address critical issues in local climate and resilience action, multilevel governance, and the unique role of the Amazon region in global sustainability. The event marked significant strides in sustainable urban development and set the stage for COP30 in Belém, Brazil. 

Katrin Stjernfeldt Jammeh, Mayor of Malmö, Sweden and newly elected ICLEI President, said: “ICLEI is a strong global force and an important network that gives voice to the cities globally. Cities stand for 70% of the greenhouse gas emissions, and it is within the cities a lot of climate adaptation has to be done. The transition cannot be sustainable if it’s not affordable. We need to put people at the center of our work, including the situation for women globally. It has been truly empowering to meet face to face at the World Congress in São Paulo and feel the force of the entire ICLEI movement. We are now more determined and inspired to get the work done.”

Gino Van Begin, ICLEI Secretary General, said: The ICLEI World Congress is a chance to show the power of our network of over 2,600 local and regional governments committed to sustainability. As a result of the Congress, ICLEI is set to initiate more than 300 programs, projects, and initiatives over the next three years, with a total investment of $100 million to bolster its Members’ sustainability efforts. Our network exists to serve these forward-thinking local and regional governments, and I’m so proud to see what they have been able to accomplish and to use the ICLEI World Congress as a moment to bolster those partnerships and commitments.”

Rodrigo de Oliveira Perpétuo, Regional Director of ICLEI South America Secretariat, said: “This was a great Congress with a clear call to action. We had more than 1,500 attendees from over 95 countries, and more than 100 mayors delivering hope, and a big, great call to action to do this work together.”

Mohamed Sefiani, Mayor of Chefchaouen, Morocco and newly elected ICLEI Vice President, said: I have been so inspired by the leadership that I see in our ICLEI cities, towns and regions. I am inspired by their unflinching efforts to understand sustainability in their contexts, by their determination to take direct action to improve the lives of their people and by their passion to work together with boldness and tenacity, facing the immense challenges head on. This Congress aimed to transform commitments into action, and the action I have seen has been remarkable – urgent, decisive action being taken across all levels of government to foster resilience, address systemic inequities and harness innovation. However, it is essential that, as an ICLEI community, we work hard to unlock finance at the city scale in order to scale up these actions to achieve the level of transformative change that we need.”

The ICLEI World Congress was the main event of the São Paulo Urban Summit, a week full of activities that highlight the fundamental role of cities. As Brazil officially assumes the presidency of the G20, replacing India, Brazilian cities will lead the U20, elevating the voices of urban centers at the heart of the G20 economies. The week also included the Metropolis Board of Directors Meeting, further reinforcing the importance of cities on the global stage.
