Indirect greenhouse effect
Environmental impact of the cold and energy efficiency

The major use of electricity to drive the compressors generates a CO ₂ emission that is more or less significant depending on the mode of electrical production, expressed in kg CO ₂ equivalent:

• in France, 0.11 kg CO ₂ /kWh ;

• in Europe, 0.56 kg CO ₂ /kWh ;

• on a worldwide average, 0.62 kg CO ₂ /kWh.

Worldwide, according to various statistics, an average of 15% of electricity produced is consumed for cooling and air conditioning. This figure is virtually identical for France.
