Air Conditioning in France: More Cooling, Higher Environmental Costs

Paris – 04.08.2026: Air conditioning is increasingly becoming an everyday feature in French homes. An article published by Franceinfo on Tuesday examines the consequences for the environment and energy supply. According to the state environmental agency ADEME, around 24 percent of households had an air conditioning system in 2025. Two years earlier, the figure was still 18 percent. According to Franceinfo, the share has nearly doubled within a decade.

According to ADEME, the available statistics range between 18 and 26 percent. The differences are explained by varying survey methods and the difficulty of consistently recording different types of equipment. Of households equipped in 2025, 13 percent cooled only one room, while 11 percent air-conditioned several rooms. Protection against summer overheating is therefore gaining considerable importance in France’s housing stock.

Electricity consumption remains comparatively low so far, but it is not without consequences. According to ADEME, air conditioning currently accounts for around one percent of final energy consumption in France’s residential sector. During prolonged heatwaves, the simultaneous use of many units can increase demand, particularly during the warmest hours of the day. The extent of the additional demand also depends on the efficiency, sizing and use of the installed technology.

In addition to electricity consumption, the climate impact also includes the handling of refrigerants. France’s Ministry for Ecological Transition points out that fluorinated greenhouse gases, which are used in parts of refrigeration and air conditioning technology, can have a strong climate impact if released. European regulations therefore govern, among other things, certifications for installation and maintenance as well as the recovery of these substances. Professional inspections are intended to prevent leaks and uncontrolled emissions.

ADEME advises first making full use of structural and organizational options: keeping shutters and other sun protection systems closed during the day, ventilating deliberately at night, and using fans to create air circulation. Better-insulated facades, suitable windows and more greenery around homes can also reduce indoor temperatures. Studies by the agency rate exterior sun protection and natural nighttime ventilation as particularly effective measures for limiting cooling needs.

If air conditioning is nevertheless necessary, the authority recommends careful selection rather than an impulsive purchase during a heatwave. Portable monoblock units are considered problematic because of their high electricity demand and limited effectiveness: the exhaust hose usually requires a window to remain open, allowing warm air to enter again. Efficient systems that are appropriately sized and professionally installed consume less energy. However, they cannot replace permanent structural protection against heat.
