Division Common definitions:

‘global warming potential’ (GWP) means the measure of how much 1 kg of the refrigerant applied in the vapour compression cycle is estimated to contribute to global warming, expressed in kg CO₂ equivalents over a 100-year time horizon;

for fluorinated refrigerants, the GWP values shall be those published in the Fourth Assessment Report adopted by the Intergovernmental Panel on Climate Change^f1 (2007 IPCC GWP values for a 100-year period);

for non-fluorinated gases, the GWP values are those published in the first IPCC assessment over a 100-year period;

GWP values for mixtures of refrigerants shall be based on the formula stated in Annex I to Regulation (EC) No 842/2006, with the values of the Fourth Assessment Report adopted by the Intergovernmental Panel on Climate Change (2007 IPCC GWP values for a 100-year period);

for refrigerants not included in the above references, the Report of the 2010 Assessment of the Scientific Assessment Panel^f2 (SAP) under the Montreal Protocol and the UNEP 2010 report on Refrigeration, Air Conditioning and Heat Pumps^f3, or newer if available before the date of entry into force, shall be used as references.
