PFAS regulation in Switzerland: Learning from European experiences

Switzerland is facing the challenge of developing smart and risk-based regulation. It is worth looking at the experiences of other countries – even if not every measure is directly transferable.

• In Austria, the focus is on selective bans on PFAS in products with a potentially high environmental impact, such as outdoor clothing. At the same time, stricter limit values for drinking water are being discussed. However, this approach must always weigh up the technical and economic consequences in order not to jeopardise the benefits.
• Denmark relies on comprehensive studies to gain a better understanding of the distribution pathways and concentrations of PFAS. This systematic collection of data provides a valuable basis for targeted measures. This must also be an important step for Switzerland.
• In Belgium, great emphasis is placed on dialogue. Authorities, scientists, and industry work hand in hand to take into account the various needs of society and to develop practical solutions. While direct exchange is helpful, it remains crucial that solutions be adapted to Swiss needs and conditions.

What does this mean for Switzerland? Our country can and should learn from these approaches without blindly adopting regulations. The circumstances in each country differ – but the approach taken by other countries offers valuable insights:

• prioritise data collection: only with a sound scientific basis can effective and targeted regulation be achieved that provides the greatest benefit for society and the environment.
• Consider risks in a differentiated way: Not all PFAS are problematic, and generally only if they enter the environment. Regulation should focus on the substances and applications that actually favour release into the environment.
• Promote dialogue: Society, industry, science and authorities must work hand in hand to find practical and sustainable solutions.

A blanket ban on PFAS would do more harm than good for the environment, the economy and society. Instead, targeted measures are needed that are based on a solid database and a risk-based approach. Switzerland has the opportunity to develop a regulatory framework that ensures the protection of people and the environment while preserving the innovative strength of industry and trade.
