Global Cooling Watch 2025: The Free Degrees - Key Messages

This key messages document summarizes the comprehensive assessment of surging heat, soaring cooling demand, and stark inequalities in access. Produced by the United Nations Environment Programme-led Cool Coalition, this second edition builds on the framework established in the first 2023 report. The document evaluates a sustainable cooling pathway combining passive cooling, low-energy solutions, high-efficiency equipment, and refrigerant phase-downs. Key findings demonstrate that business-as-usual demands will triple energy loads by mid-century, whereas this updated, deeper analysis of hybrid systems proves that integrated strategies can slash emissions by nearly one hundred per cent when paired with grid decarbonisation.
