Considering the emission reduction objective of the proposed PFAS restriction, we believe that controlling F-gas emissions under the existing (and the upcoming strengthened) regulatory framework would effectively and proportionately minimize their emissions and enable the continued, safe use of these critical technologies to advance decarbonization, electrification, global climate targets, and much more.

Linde feedback and concerns on the proposed PFAS restriction Linde as one of the refrigerant distributors in Northern Europe is fully committed to minimizing release of PFAS to the environment by continuously investing in circular economy for refrigerants including refrigerants that contain PFAS with the aim to keep refrigerants in a closed circle until they reach the end of their life cycle and move to our waste management partners where a well-controlled process is applied which destroys PFAS by destroying fluorocarbon structure and even enables recovery of hydrofluoric acid for reuse.
