We’re the Mayors of Paris, Milan and Phoenix. The Heat Crisis Has Us All Facing the Same Question
Our three cities are learning from each other about how to protect residents. These climate policies are also public health measures
TL;DR
- Extreme heat is no longer an exceptional event but an increasingly familiar part of summer, posing a significant challenge to urban leadership.
- Phoenix, Paris, and Milan are collaborating through networks like C40 Cities to share best practices for heat response and mitigation.
- Phoenix has implemented strategies such as requiring significant shade coverage in new developments, applying cool surface treatments, providing 24-hour cooling centers, and mandating safe indoor temperatures for renters.
- Paris has created over 1,400 'cool spots' within a seven-minute walk for all residents and extended hours for public facilities during heatwaves.
- Milan is expanding its 'Open Squares' program to integrate cool spaces with trees and green surfaces and offers support services for the elderly and vulnerable.
- Extreme heat is the deadliest climate hazard, disproportionately affecting older residents, young children, outdoor workers, and lower-income communities.
- Heat adaptation measures are also viewed as public health measures, investments in local economies, and practical improvements for city livability.
- Cities need more support, funding, and flexibility from national governments to develop effective adaptation strategies and early warning systems.
