We scale up clean cooling solutions.

Clean Cooling Collaborative (formerly K-CEP) is an initiative of ClimateWorks Foundation focused on transforming the cooling sector and making efficient, climate-friendly cooling accessible for all.

About us

Working collaboratively with our funding and implementing partners, we've supported gigaton-scale emissions reductions and improved access to clean cooling.

In 2021, we refreshed our strategy and updated our name to reflect our revised scope of work. Now, as the Clean Cooling Collaborative, we will continue to build on our past efforts to place cooling on the global agenda by catalyzing organizations, companies, and governments to bring efficient, climate-friendly cooling policies, financing, and technology solutions to the world.

Our team

The Clean Cooling Collaborative team, under the governance of its Funder Advisory Committee, sets the strategic framework of the program, oversees investment in cooling interventions, manages programmatic partnerships and reporting, and tracks progress

against our results framework, with the aim to help funders and partners maximize the climate and equity benefits of efficient, climate-friendly cooling.

Funding partners

Through the generous support of our current and previous foundation, individual, and government partners, we have been able to advance our mission to make efficient, climate-friendly cooling accessible to all.

Our history and impact

In 2016, leading climate foundations collaborated ahead of the Montreal Protocol meeting in Kigali, Rwanda, and pledged more than $50 million to create the largest-ever fund of its kind for action on efficient, climate-friendly cooling. The following spring, the Kigali Cooling Efficiency Program (K-CEP) was born and charged with strategically programming interventions for the funds under a directive to advance appliance efficiency reforms alongside efforts to support the implementation of the new global phase down of hydrofluorocarbons (HFCs) under the Kigali Amendment.

Since then, and with the support of our implementing and funding partners, we have secured sizable greenhouse gas emissions reductions and helped place cooling on the global agenda.

Read our 2017-2021 impact report to find out how as K-CEP we created lasting and meaningful impact, with the aim of ensuring efficient, climate-friendly cooling for all.
