Written by the Refrigeration Team, specialists in refrigerant gases and EU F-Gas compliance. Last updated: 21 May 2026. R-134a remains one of the most widely used refrigerants in the world. With a GWP of 1,430 and a non-flammable A1 classification, it still runs in the large majority of vehicles registered..

Written by the Refrigeration Team, specialists in refrigerant gases and EU F-Gas compliance. Last updated: 16 September 2026. R-134a carries a GWP of 1,430 under Annex I of Regulation (EU) 2024/573. That value sits below the 2,500 threshold behind today’s servicing bans, and above the 750 threshold that will apply..

Written by the Refrigeration Team, specialists in refrigerant gases and European F-Gas compliance. Last updated: 20 May 2026. R-134a (GWP 1,430) has seen its distributor price multiply 9.5-fold since 2014, according to data prepared for the European Commission in Q4 2025 (Cooling Post, 2025). Two fluids are competing to take..

R-454B is an A2L low-GWP refrigerant blend that clears the EU F-Gas Regulation (EU) 2024/573 threshold of GWP < 750 for single-split air conditioning systems, with a Global Warming Potential of 466, sitting 76% below R-410A’s AR5 GWP of 1,924 (Regulation (EU) 2024/573). It’s a zeotropic blend of two HFC/HFO..

A “low-GWP refrigerant” in 2026 is any working fluid with a Global Warming Potential below the ceiling the EU F-Gas Regulation (EU) 2024/573 sets for its equipment category (European Commission, F-gas legislation). That ceiling isn’t one number. It’s tiered: GWP 2,500 is the outer limit for stationary refrigeration, 750 applies..

European heat pump sales bounced back in 2025: 980,000 units sold across 13 countries in the first half of the year, a 9% rise after a steep 21% drop in 2024 (EHPA, 2025). Whether your home runs a heat pump, a split air conditioner, or an older AC, one question..

Regulation (EU) 2024/573 reshaped the European refrigerant market when it entered into force in March 2024, and the sharpest deadlines are here now. The EU’s updated F-Gas rules cut HFC production quotas to just 31% of the 2015 baseline for the current period and will tighten to 24% in 2027..
