Air conditioners are a double burden when it comes climate change. They use the extremely potent greenhouse gases HFCs and use a significant amount of energy.  

With the world’s air conditioners expected to increase from 900 million units today to 2.5 billion in 2050 this double burden in set to accelerate to unprecedented levels. 

To learn more about HFCs and how phasing down their use can make a real difference in the fight against climate change, watch the video below.

The Institute for Governance and Sustainable Development and a team of experts are working to help governments and industry around the world, including in India and China, to increase the energy efficiency of air conditioners in parallel with the phase down of super-polluting HFC refrigerants.

Since 2009, we have committed more than $26 million to the global phase-down of HFCs. 

This grant also forms the basis of CIFF’s commitment to the Clean Energy Ministerial’s Advanced Cooling Challenge , a campaign urging governments and industry to develop and deploy at scale super-efficient, smart, climate-friendly, and affordable cooling technologies.


A rapid global phase down of hydrofluorocarbons (HFCs) has the potential to mitigate 100 billion tonnes of carbon dioxide equivalent or more.  

But this is only half of what can be achieved through the phase down of HFCs. By increasing energy efficiency of air conditioners at the same time it is possible to mitigate an additional 100 billion tonnes of carbon dioxide equivalent by 2050. 

A double transition in the air conditioning sector could avoid building up to 2500 peak power plants globally by 2050, including 710 in China and 510 in India.
