APPENDIX 1 - Fluorinated greenhouse gases (F gases) subject to the EU Fluorinated Greenhouse Gases regulation 2014 (as listed in Annex 1 of that regulation) This is a table of fluorinated greenhouse gases (F gases) regulated by the EU. The table includes the global warming potential of each F gas. You can use the global warming potential to calculate the carbon dioxide equivalent weight of an F gas.

For refrigeration, air conditioning, heat pumps, stationary fire protection and refrigerated trucks and trailers, all checks should be carried out by a certified person.
