The second edition of UNEP’s Global Cooling Watch Report takes a deep dive into one of the decade’s most urgent challenges: surging heat, soaring cooling demand and stark inequalities in access.
Produced by the UNEP-led Cool Coalition, the report provides a comprehensive assessment of the rapidly growing global demand for cooling and the need for climate-friendly solutions to the issue.
The 2025 report builds on the first Global Cooling Watch (2023), which established the Sustainable Cooling Pathway framework. The new edition deepens analysis of intensifying extreme heat and its effect on cooling demand, improved assessment of passive cooling, and coverage of low-energy and hybrid systems that reduce power use while maintaining comfort.
Released at the 30th Climate Change Conference, the launch of the report has been accompanied by a special announcement on the Mutirão Contra o Calor Extremo / Beat the Heat implementation drive – a collective effort led by the Brazil COP30 presidency and UNEP Cool Coalition underscoring the urgency to strengthen national-to-local collaboration and bridge gaps in finance, policy, and delivery for extreme heat resilience and sustainable cooling locally.
