Urban Heat Risk Management

Global temperatures have steadily risen over recent decades, driven by greenhouse gas emissions, bringing the planet dangerously close to the 1.5°C threshold identified as critical for avoiding the most catastrophic impacts1 of the climate crisis. These rising temperatures pose significant risks, especially in urban areas where heat stress exacerbates health, social, and economic challenges. Prolonged exposure to extreme heat, particularly temperatures above 35°C, can lead to severe health crises and even death, while globally threatening the productivity of billions of workers.

This urban heat risk management resource package synthesises insights from over 30 global case studies and deep-dives into five cities—Amadora (Portugal), Incheon (Republic of Korea), Quito (Ecuador), Cape Town (South Africa), and Nairobi (Kenya). Through interviews and extensive literature reviews, this report identifies governance structures, best practices, and challenges in
managing urban heat. It also provides a series of recommendations useful for both local and national governments in developing targeted, effective, and sustainable strategies for mitigating urban heat risks.
