Cooling demand may triple by 2050, doubling emissions unless action is taken, UN warns.

Global cooling demand could triple by 2050, potentially doubling cooling-related emissions to 7.2 billion tonnes of CO2 equivalent without action, according to a UN report released at COP30. The UNEP’s Global Cooling Watch 2025 warns that rising heatwaves make cooling essential infrastructure, and a Sustainable Cooling Pathway could cut emissions by 64%—up to 97% with clean energy—while expanding access for billions, especially in the Global South. The approach promotes passive cooling, efficient technologies, and faster phase-down of harmful refrigerants. Over 180 cities and 72 countries have joined the 'Beat the Heat' initiative, urging governments to integrate cooling into climate plans, building codes, and urban design.
