EU legislation to control F-gases
To control emissions from fluorinated greenhouse gases (F-gases), including hydrofluorocarbons (HFCs), the European Union has adopted two legislative acts: the ’MAC Directive’ on air conditioning systems used in small motor vehicles, and the ‘F-gas Regulation’ which covers all other key applications in which F-gases are used. The MAC Directive prohibits the use of F-gases with […]

Fluorinated greenhouse gases 2021
Fluorinated greenhouse gases (F-gases) contribute to climate change and in 2019 made up 2.3% of total EU greenhouse gas emissions. F-gases have a range of applications, particularly in the refrigeration, air conditioning and heat pump sector. Most F-gases have much higher global warming potentials than other greenhouse gases. This briefing outlines the important trends in […]
