CO2 emissions from air conditioning, 57th Informatory Note on Refrigeration Technologies.

Summary

Air conditioning is essential for improving people’s comfort and health, indispensable for the economic development of hot, humid regions, and made increasingly necessary by the more frequent heat waves caused by global warming. Yet it nevertheless contributes to the CO2 emissions that fuel this warming.
According to IIR estimates, air conditioning accounts for over 12% of electricity consumption and 5% of energy-related CO2 emissions worldwide.
It is therefore essential to implement strong measures to mitigate the climate impact of air conditioning. Only a real break in the rate of increase in energy efficiency, combined with a sharp reduction in the impact of refrigerant leaks, would make it possible to achieve an objective of reducing air conditioning-related emissions by 1/3, despite the 2.5-fold increase in the number of air-conditioning equipment by 2050 projected by the new model developed by the IIR.
It is also necessary to act upstream to reduce the cooling needs of indoor spaces, and to adopt passive cooling strategies right from the design stage of buildings. Priority should also be given to highly energy-efficient technologies, such as district cooling, and those using renewable energies, such as solar cooling.
