A diverse panel of global experts begins work on the IPCC Special Report, set for release in 2027, to address climate risks and solutions for urban areas.
The Intergovernmental Panel on Climate Change (IPCC) has officially commenced work on its Special Report on Climate Change and Cities, selecting 97 experts from 56 countries to serve as Coordinating Lead Authors, Lead Authors, and Review Editors. This milestone marks the beginning of the report’s drafting process, set to be released in March 2027 as the first publication under IPCC’s seventh assessment cycle.
Why This Report Matters
With over half the global population residing in urban areas, and this proportion expected to rise by 2050, cities are at the forefront of climate change challenges and solutions. The report aims to assess the latest science on climate impacts, risks, and potential adaptation and mitigation strategies specifically tailored for urban settings.
“The IPCC Special Report on Climate Change and Cities is a call to action 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 IPCC Working Group II.
A Diverse Panel of Experts
The selection process for the 97 experts was rigorous, with 1,201 nominations received from IPCC’s national focal points and observer organizations. The final list reflects:
- 53% women representation
- 54.6% experts from developing countries and transitioning economies
- Nearly one-third new participants in the IPCC process
This diverse representation ensures a broad spectrum of scientific, technical, and socio-economic expertise, integrating voices from various geographic regions and professional backgrounds.
The Road Ahead
The Special Report’s development follows an outline approved during the 61st IPCC Session in Sofia, Bulgaria (July–August 2024). In the second half of 2025, a call will be issued for experts to participate in the Expert Review of the First Order Draft. This provides an opportunity for researchers, policymakers, and stakeholders to contribute to shaping the findings.
“The selection of authors is a crucial step in the report’s production, reinforcing the global scientific community’s commitment to climate action in urban areas,” noted Joy Pereira, Co-Chair of Working Group III.
A Global Commitment to Climate-Resilient Cities
The increasing number of nominations for IPCC contributions highlights the scientific community’s growing interest in urban climate resilience. This report is expected to provide actionable insights that can guide policymakers, urban planners, and climate advocates in building sustainable, climate-resilient cities worldwide.
As the drafting process progresses, experts and stakeholders are encouraged to engage with the IPCC to ensure that the final report delivers comprehensive, science-backed solutions for the cities of the future.
