The UNEP Cool Coalition is a global platform driving system-level change on sustainable cooling. Launched in 2019 as a flagship initiative of the UN Secretary-General's Climate Action Summit, the Coalition brings together over 250 actors — including governments, businesses, cities, and financial institutions — to deliver efficient, climate-friendly cooling solutions aligned with the Paris Agreement, the Kigali Amendment, and the 2030 Agenda.

Showcasing global action on sustainable cooling and extreme heat resilience through advocacy, science, and joint implementation, the Coalition operates through dedicated working groups spanning passive cooling, urban heat adaptation, lifecycle refrigerant management, energy performance standards, and National Cooling Action Plans. Its flagship initiative — the Global Cooling Pledge — mobilizes government and private sector commitments to accelerate the transition to sustainable cooling worldwide. Active projects include the India Cooling Programme, the Beat the Heat campaign, and urban cooling initiatives across Vietnam and Cambodia. Hosted by the United Nations Environment Programme (UNEP), the Cool Coalition serves as the world's preeminent multilateral forum for coordinating the global response to the cooling challenge.
