F-gases are highly potent greenhouse gases that contribute to global warming when released into the atmosphere. Some F-gases, such as sulfur,many choosing climate-friendly, energy-efficient, and safe alternatives are essential hexafluoride (SF6), have a 24 300 times greater impact on the climate than CO2, while others contribute to Ozon depletion. F-gases are commonly used in industry and heat exchangers, including refrigerators and air-conditioning systems. These gases are regulated around the globe, including within the EU.
The F-Gas Regulation (EU) 2024/573 entered into force on 11 March 2024, introducing a more stringent phase-out schedule for hydrofluorocarbons (HFCs), the most common F-gases. This means using HFCs will be progressively prohibited in most products and equipment by 2050, with a few exempted sectors.
To reduce F-gas use and emissions, it is essential to choose climate-friendly, energy-efficient, and safe alternatives. Given the many other options available for specific uses, their suitability should be assessed separately for each equipment category. This section explores climate-friendly alternatives to F-gases, their climate and environmental benefits, as well as corresponding regulatory frameworks. It also presents technological advancements in this sector and their implications for sustainable development.
