As global temperatures rise, extreme heat events are becoming more frequent and severe, posing significant risks to public health, infrastructure, and ecosystems worldwide.

In response to this growing threat, the UN Secretary-General has issued a Call to Action on Extreme Heat, emphasizing the urgent need for coordinated global efforts.

This report examines the current landscape of extreme heat management among United Nations entities and International Organizations (UN entities and IOs), identifying challenges, opportunities, and strategies for improving collaboration and governance to support this call to action.
