Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, if he will make an assessment of the potential merits of banning per- and polyfluoroalkyl substances where alternatives are available.

The Government has already prohibited three key PFAS through our domestic legislation on Persistent Organic Pollutants (POPs), which implements the UN Stockholm Convention on POPs.

Defra, Scottish and Welsh Ministers agreed that understanding the risks posed by PFAS was a top priority for the UK REACH Agency (HSE) under the first UK REACH Work Programme, 2021-22. Defra asked the EA and HSE to examine the risks posed by PFAS and develop a 'Regulatory Management Options Analysis' (RMOA), to assess uses, exposure routes, and risk management actions specific to Great Britain in an evidence-based and proportionate way.

This RMOA was published in April 2023 and recommended work under UK REACH to reduce PFAS emissions by developing UK REACH restrictions. Following this, we have started work on a UK REACH dossier investigating whether to restrict the use of PFAS in firefighting foams, and we are exploring further measures relating to PFAS. The UK REACH restriction dossier on PFAS in fire-fighting foams is due to be published for consultation soon. As part of this, the Health and Safety Executive (HSE) as the Agency for UK REACH conducted a detailed analysis of PFAS alternatives.
