The planet is warming. Let’s cool it together.
As global temperatures rise, demand for cooling could triple by 2050, driving up greenhouse gas emissions.

Today, most air conditioning and refrigeration consume massive amounts of energy and release super-polluting greenhouse gases, damaging our climate.

Cooling already produces 7-11% of the world’s greenhouse gas emissions, a share that could double by midcentury.

Moreover, cooling is critical to saving lives. Globally, more than 1.1 billion people face heat-related threats. Lack of access to cooling makes it more difficult for people to escape poverty, stay healthy, learn, be economically productive, and keep food fresh. Access to cooling is also a racial and social justice issue, with underserved and lower-income communities and countries feeling adverse effects the most.

Clean Cooling Collaborative

Formerly the Kigali Cooling Efficiency Program (K-CEP), Clean Cooling Collaborative is a ClimateWorks initiative advancing efficient, climate-friendly cooling for all.

To sustainably cool people and the planet, the initiative focuses on:

Super-efficient appliances

Heat pumps, efficient air conditioners, fans, refrigerators, and other high-performance cooling technologies can significantly reduce energy use. Learn more.

Passive cooling

Urban greening, shading, solar-reflective roofs, improved building envelopes, and better urban design can provide natural cooling, reducing the need for energy-intensive mechanical cooling like air conditioning. Learn more.

Climate-friendly refrigerants

Natural refrigerants and those with low global warming potential can replace chemicals that release pollutants thousands of times more damaging to the climate than carbon dioxide. Learn more.

Integrated solutions

Clean cooling supports several climate and development goals, including building electrification, grid decarbonization, food safety, and access to vaccines and other life-saving medications. Learn more.

K-CEP: Scaling up clean cooling for all (2017-2021)

IEA estimates that once fully implemented, progress supported by K-CEP and its partners will reduce CO2 emissions by 4.2 Gt by 2050 and achieve $960 billion in cost savings over the same period.

In 2016, 17 foundations and individuals collaborated ahead of the Montreal Protocol meeting in Kigali, Rwanda. They pledged more than $50 million to create the largest-ever fund of its kind for action on efficient, climate-friendly cooling. The following spring, ClimateWorks launched K-CEP.

Between 2017 to 2021, K-CEP — now the CleanCooling Collaborative — grew from a bright idea to a thriving initiative working in 57 countries to achieve results at scale.

Now, as the Clean Cooling Collaborative, the initiative is building on its efforts to elevate cooling on the global agenda — catalyzing governments, companies, and organizations to bring efficient, climate-friendly policies, financing, and technologies to the world.
