This type of refrigerant has particular characteristics of environmental acceptability, such as non-flammability and nonharmfulness to the ozone layer.

Applying CO₂ in refrigeration systems significantly reduces the amount of greenhouse gas emissions in the atmosphere, which are the origin of climate change.

Furthermore, CO₂ systems in various applications have a much more efficient potential than current refrigeration and air conditioning systems that use HCFC - HFC - HFO synthetic refrigerants.
