Per- and polyfluoroalkyl substances (PFAS) are a large class of thousands of synthetic chemicals that are used throughout society. However, they are increasingly detected as environmental pollutants and some are linked to negative effects on human health.

This page from the European Chemicals Agency provides background on PFAS chemicals and their use in a number of products, including construction materials, paints and chrome plating.

On 13th January 2023, the European Commission issued a proposal that would ban the manufacture and use of PFAS chemicals, including those used in building materials. 

The details of the proposed restriction of around 10,000 per- and polyfluoroalkyl substances (PFASs) are now available on ECHA’s website. ECHA’s scientific committees have begun to evaluate the proposal in terms of the risks to people and the environment, and the impacts on society, in accordance with the below timeline.  A six-month consultation began in March 2023 and will close on 25 September 2023.

Document: Consultation on a proposed restriction on the manufacture, placing on the market and use of per- and polyfluoroalkyl substances (PFAS)

This study, commissioned by DG Environment for the European Commission and produced by Wood and Ramboll.  The objective was to assess the use of PFASs and fluorine-free alternatives in textiles, upholstry, carpets, leather and apparel, including specific focus on volumes of use, technical function, and emissions.

Non-fluorine alternatives considered were hydrocarbons, silicones, dendrimers, polyurethane, nanomaterials, and alternative technologies.  The study makes recommendations for policy, including a REACH restriction on the placing on the market and use of these products that contain any PFAS, and a listing under the Stockholm Convention.  It is also recommended in the report that a restriction could be combined with voluntary industry measures and provisions in public procurement to encourage substitution of PFAS before mandatory legislation is introduced.

HBN tested 94 commercially available paint products for the presence of harmful per- and polyfluoroalkyl substances (PFAS), called “forever chemicals”. Approximately 50% of ‌paints tested positive for fluorine, a marker of PFAS. Review the details of our findings and the recommended actions you can take.
