Unlivable: How cities in Europe and Central Asia can survive ‒ and thrive ‒ in a hotter future

This report explores the emerging challenge of extreme heat, explaining what is at stake, what cities are doing, and what needs to happen next. Extreme heat intensifies droughts by accelerating evaporation and drying out soils, reducing water availability for agriculture, hydropower, and urban supply. It elevates wildfire risk by desiccating vegetation and extending fire seasons, which in turn can destroy infrastructure and displace communities.

The report identifies cities as both the frontline victims and potential leaders in building resilience, offering a roadmap of practical, high-impact actions. With targeted investments, cities can cool their environments, protect vulnerable populations, and safeguard economic performance in an increasingly hotter world.
