Phoenix's Heat Safety Model Offers a Blueprint for the World

As the world grapples with the devastating effects of extreme heat, a US city is emerging as a beacon of hope. Phoenix, Arizona, has been at the forefront of the battle against heat-related deaths, and its innovative approach is starting to pay off.

Phoenix's heat safety model offers a unique opportunity for the world to learn from a city that has been proactive in addressing heat-related deaths.

Phoenix's heat safety model focuses on increasing access to cooling centres, offering free air conditioning, and repairing or replacing faulty air conditioning systems for low-income residents. The city's consistent and open access to cool spaces has seen a significant decline in heat-related deaths, from 645 in 2023 to 405 in 2025. Officials attribute part of the decline to policy changes, which have prioritized heat safety and targeted vulnerable populations.

As Jennifer Marlon, a Yale University researcher, notes, Phoenix's experience offers a valuable lesson for the world. The city's proactive approach to heat safety is a stark contrast to the reactive measures often taken by other communities. By investing in heat safety infrastructure and prioritizing vulnerable populations, Phoenix is providing a blueprint for cities worldwide to follow. As temperatures continue to rise, the world has a lot to learn from Maricopa County's success.
