Cooling is central to health, prosperity, and the environment. Efficient, clean cooling for all underpins many Sustainable Development Goals and represents an opportunity to avoid substantial climate and air pollutant emissions.
Energy demand for cooling is the fastest growing end-use in buildings, with ten air conditioners expected to be sold every second over the next 30 years. There is consensus in the scientific community that enhancement of energy efficiency in the cooling sector is a strategic, near-term opportunity to realize significant climate and clean air benefits.
The Kigali Amendment to the Montreal Protocol entered into force in January 1st, 2019. The phase down of HFC refrigerants under the amendment has the potential to avoid up to 0.1˚C of warming by 2050 and up to 0.4℃ by 2100. The economic, environmental, and health benefits of catalyzing simultaneous energy efficiency improvements, in concert with the HFC phase down, supports reduced energy consumption and avoided emissions of CO2 and black carbon, which can potentially double the climate benefit of the phase down alone.
To capture this opportunity, the Efficient Cooling Initiative brings together governments, intergovernmental organizations, and the private sector to build high-level political leadership and facilitate collaboration among stakeholders. The aim is to enhance energy efficiency in the cooling sector while countries implement the phase-down of HFC refrigerants under the Montreal Protocol.
