What substances are being phased out under F-Gas regulations?

The phase-out under the F-Gas regulations primarily targets high-global warming potential (GWP) hydrofluorocarbons (HFCs) and other fluorinated gases that are known to have significant impacts on climate change. These substances are being reduced in usage due to their contribution to greenhouse gas emissions, which has been recognized as a critical environmental issue. The F-Gas regulations aim to limit these types of gases to encourage the use of more environmentally friendly alternatives.

The regulations do not focus on low-GWP natural refrigerants, which are seen as a more sustainable option, nor do they address all gases used in refrigeration indiscriminately. Additionally, the regulations are distinct from those targeting ozone-depleting substances, which are governed by different international agreements such as the Montreal Protocol. Therefore, the correct focus under F-Gas regulations is on phasing out high-GWP HFCs and certain fluorinated gases to help mitigate climate change impacts.
