Last January, five European countries - Denmark, Germany, Netherlands, Norway, and Sweden - submitted a proposal to the European Chemicals Agency (ECHA) to restrict PFAS (per- and polyfluoroalkyl substances) in the EU under the Registration, Evaluation, Authorisation, and Restriction of Chemicals (REACH) regulation. The group are calling for an EU ban on PFAS as early as 2026, pointing to recent studies that have linked the chemicals’ exposure to a wide range of health problems. The proposed restrictions will have global ramifications given that imported products will be included in the ban. It will also mean that the entire supply chain must be examined to ensure that nothing – intentionally or not - contains PFAS.
