F-gases are commonly used in vehicle air conditioning units as they are non-flammable, non-toxic, and have good thermodynamic properties. However, they are synthetic compounds that contain fluorine and carbon atoms, and their use is classified as a potential contributor to climate change.   According to the European Environmental Agency (EEA), F-gases have a global warming potential of 1,000 times greater than carbon dioxide. What’s more, the use of F-gases in air conditioning accounts for approximately 5% of the EU's total greenhouse gas emissions.  These gases are likely to escape during vehicle maintenance, particularly during recharging or repair and end-of-life disposal of vehicles. As the number of vehicles on the roads continues to increase, so does the likelihood of F-gas emissions, making it vital to address the issue. Finding alternative solutions to air conditioning that do not rely on these harmful gases has become a big priority and Governments and manufacturers are working to phase out F-gases and promote more sustainable and environmentally friendly options.
