In a world where cities are both the frontlines and catalysts for climate action, the Intergovernmental Panel on Climate Change (IPCC) is setting the stage for a transformative discussion on urban resilience. From March 10 to 14, nearly 100 top experts from over 50 countries are convening in Osaka, Japan, for the First Lead Author Meeting of the IPCC Special Report on Climate Change and Cities.
Hosted at the Osaka International Convention Centre by Japan’s Ministry of Environment, this high-stakes gathering brings together a diverse array of climate scientists, urban planners, policymakers, and sustainability experts. These Coordinating Lead Authors and Lead Authors, handpicked by IPCC’s three Working Groups, will be the driving force behind a pivotal report designed to shape the future of climate-resilient urban development.
A Turning Point for Cities in the Climate Crisis
“The IPCC Special Report on Climate Change and Cities will provide a foundation for all of us to harness the full potential of our cities in tackling climate change, ensuring that they are resilient, inclusive, and sustainable for generations to come,” said Winston Chow, Co-Chair of Working Group II. “We look forward to the insights that our invited experts will bring to developing a robust and actionable report.”
The meeting marks the beginning of the drafting process for this landmark report, the only Special Report of the seventh assessment cycle, scheduled for completion in March 2027. This first phase will focus on selecting and assessing the most up-to-date scientific literature, structuring the report’s chapters, and establishing a collaborative research agenda.
Why This Report Matters
As urban areas continue to expand and climate risks intensify, cities are at a crossroads. This report will offer a cutting-edge synthesis of scientific knowledge on how cities contribute to climate change, how they are impacted by it, and most importantly, what can be done to mitigate and adapt. From innovative green infrastructure to policy-driven emissions reductions, the report aims to serve as a critical resource for city leaders worldwide.
“It is exciting to meet leading experts from all corners of the world, bringing together diverse perspectives and expertise to draft this Special Report,” said Diana Ürge-Vorsatz, Chair of the Scientific Steering Committee for the scoping of the report and Vice Chair of the IPCC. “We applaud the commitment of scientists and practitioners who volunteer their time to work toward a more livable future for our cities.”
What’s Next?
This meeting in Osaka is just the beginning. Over the next two years, authors will engage in multiple review cycles, incorporating feedback from governments, scientists, and the public. The final report, expected in 2027, will be a key tool for city planners, policymakers, and international bodies striving to integrate climate resilience into urban development strategies.
As cities continue to grow, so does their responsibility in the fight against climate change. With the right strategies, they can be part of the solution—innovating, adapting, and leading the way toward a sustainable and climate-resilient future.
