About the Cooling Hub

The CCAC’s seven Hubs address agriculture, cooling, fossil fuel, heavy-duty vehicles, household energy, waste and national planning. Through these Hubs, the CCAC aims to advance action on SLCPs mitigation in key sectors. For more information about the Hubs, visit the About the Hubs page.

The Cooling Hub brings together governments, inter-governmental and non-governmental organizations along with private sector leaders 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.

Reducing SLCP emissions from cooling

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 on January 1st, 2019. The phase down of HFC (hydrofluorocarbon) 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.


Emissions from air conditioning and refrigeration are expected to rise 90% from 2017 levels by 2050. This increase would result in emission of 12 GtCO2e, equivalent to a third of our total emissions in 2017.
There are 1.6 billion residential air conditioners in use today. Without fast action, that number could triple by 2050 requiring USD $3.2 trillion in power generation.
A 30% improvement in energy efficiency of room air conditioners can save enough energy to avoid building up to nearly 1,600 500MW peak power plants by 2030, and up to 2,500 by 2050.


The Cooling Hub is co-led by Canada and Maldives. Co-leadership by countries ensures government engagement and ownership of the solutions. Co-leads provide valuable insights into the policy process to help ensure implementation is practical from a national perspective.

The Cooling Hub Leadership Group consists of both state and non-state members that provide guidance and expertise, and connect the Hub to activities underway beyond the CCAC. The CCAC recently published an Inventory of International Cooling Programmes and Initiatives to promote exchange, transparency and efficiency among those engaged in the cooling sector, with a view to avoiding duplication and identifying potential gaps for future work in this area.

  • States: Cambodia, France, Germany, Japan, Mexico, Nigeria, United Kingdom
  • Non-States: AFD, ClimateWorks Foundation, IGSD, SEI, UNDP, UNIDO, World Bank, WMO


By 2025, the CCAC will have significantly raised global awareness of the cooling sector’s ability to combat climate change, will have increased ambitious action, and will have mobilized political support for finance to assist developing countries transition towards climate-friendly cooling beyond that of the Multilateral Fund of The Montreal Protocol.  

By 2023, all CCAC partner countries have ratified the Kigali Amendment or have demonstrated intent to ratify and have started the ratification process.

By 2030, the CCAC will have significantly enhanced the environmental benefits of the Kigali Amendment by reducing HFC and energy-related emissions in the cooling sector.

By 2024, all CCAC cooling industry partners provide commitments on how they will support and facilitate a faster phase-down of HFCs and enhance energy efficiency in the sector.

Action to achieve these goals: 

Dedicate one CCAC Ministerial to cooling (by 2025) and hold one Ministerial roundtable that results in commitments by governments and industry;

  • Promote having cooling on agendas of high-levels forums (G-7, G-20, UN Ministerial meetings, etc.);
  • Highlight importance of Kigali ratification and implementation at each Annual Ministerial Event;
  • Demonstrate how to achieve accelerated HFC consumption and emission reductions while enhancing energy efficiency through: (1) technical reports, case studies, and strategic advice, and (2) project concepts that help developing countries advance the HFC phase-down and/or demonstrate zero or low-GWP and energy efficient cooling technologies.
  • Develop and disseminate tools and guidance to help partner countries: identify and adopt zero or low-GWP, energy efficient alternative technologies; enhance energy efficiency for new and existing equipment; reduce the needs for cooling through nature based and passive solutions; properly manage and dispose of HFC/fluorocarbon refrigerant banks, including in government operations. Provide guidance on how to include HFC emissions reductions in countries’ updated NDCs and national plans.

Achievements to date

Since its launch in 2019, the Efficient Cooling Initiative has engaged with leaders and decision makers to take steps that improve energy efficiency in the cooling sector. 

  • The initiative held a high-level ministerial roundtable on the margins of the 31st Meeting of the Parties to the Montreal Protocol to discuss ways to accelerate the global transition to ozone-friendly, lower-global warming potential (GWP) efficient cooling. Hosted by Nigeria’s Minister of Environment, the event included high-level representatives from seven countries.  
  • Together with Japan’s Ministry of Environment, we developed and launched its Initiative on Fluorocarbon Life Cycle Management (LMI). The LMI focuses on an important management gap – end of life disposal of fluorocarbon refrigerants.   
  • A high-level ministerial roundtable on the margins of COP 25, was co-organized with Japan’s Minister of Environment, to discuss the role countries can play to accelerate progress on efficient cooling and fluorocarbon life cycle management. Countries were invited to join the Biarritz Pledge for Fast Action on Efficient Cooling and Japan’s new Initiative on Fluorocarbon Life Cycle Management.
