In view of Montreal, Kyoto and Paris climate agreements the refrigerants corresponding to the main tradition of these documents that is the greenhouse gases impact lowering are examined. The hydrofluoroolefins (HFO) produced today, their properties, qualities and defects as well as the principal of technical designation are examined in detail; they are compared with R134а that is the most used now HFC. Also the mixtures of HFO with other refrigerants mainly with HFC are described. The plan of consecutive phase out of HFC refrigerants used today depending on their greenhouse potential is given. The increase of СО2 emissions of refrigerants, when calculating these emissions using the LCCP index instead of TEWI, was estimated. It was shown that natural refrigerants that are not the universal panacea may be considered today as the most reliable alternative to synthetic ones.
