The Kigali Cooling Efficiency Program (K-CEP), a collaboration among 18 foundations including MacArthur, will direct $52 million to help developing countries transition to energy efficient, climate-friendly, affordable cooling solutions. K-CEP supports the Kigali amendment of the Montreal Protocol. Under the amendment, 197 countries committed to cut the production and consumption of hydrofluorocarbons (HFCs) – potent greenhouse gases used in refrigeration and air conditioning – by more than 80 percent over the next 30 years. K-CEP will help the Kigali amendment succeed by making cooling more energy efficient simultaneous with the phase-out of HFCs.
