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.Key finidngs from the report include:Collaboration & Engagement - UN and other entities have produced substantial work related to extreme heat, but much of this is conducted with limited inter-organizational collaboration, reducing its impact. Entities at lower stages on the heat resilience curve tend to have fewer collaborative relationships, indicating a need for targeted support and partnership building.Resource & Capacity Challenges - Current efforts within UN and other entities are hampered by limited funding, expertise, and institutional support. While most entities agree that extreme heat aligns with their mission and mandate, competing priorities challenge resource allocation.Governance & Integration - Heat resilience efforts are typically integrated into broader climate resilience initiatives rather than developed as stand-alone programmes. UN and other entities recognize the critical importance of strengthening heat risk governance and promoting integrated planning at national and local levels.
