EU refrigerant regulations impact older vehicle air conditioning maintenance

European Union regulations regarding fluorinated greenhouse gases are leading to a gradual phase-down of the R134a refrigerant, which is widely used in older vehicle air conditioning systems. While R134a has been prohibited in new cars since 2017, millions of existing vehicles still rely on it. Under EU regulations, the available quota for such gases is set to decrease significantly, dropping from 31% in 2024 to 17% in 2027 and 9% by 2030, with a total phase-out planned by 2050.

The German automobile club ADAC has warned that this reduction could lead to increased maintenance costs, supply shortages, and difficulties in servicing older vehicles. Although some services offer conversions to the newer R1234yf refrigerant, experts note that older systems are often not designed for it, and there is a lack of clear technical approvals and manufacturer certifications for such modifications.

Additionally, there are safety concerns regarding cheap, unapproved DIY refill kits containing butane or propane sold online. These products are not designed for automotive air conditioning and pose a significant risk of fire or explosion. In Poland, separate studies indicate that many vehicles are already operating with insufficient refrigerant levels, which can lead to compressor damage.
