A recent investigation by the Forever Lobbying Project has revealed that addressing per- and polyfluoroalkyl substances (PFAS) contamination across Europe could cost over € 2 trillion over the next two decades. This equates to an annual expense of approximately € 100 billion, highlighting the immense financial strain required to tackle the widespread pollution caused by these synthetic chemicals.

Understanding PFAS and Their Environmental Impact
PFAS are synthetic substances widely used in various industries, including food packaging. Once discarded, these chemicals enter the environment through multiple pathways such as landfill leaching, runoff from stormwater, flawed containment systems, or even gas emissions. Their durability makes them nearly indestructible, and any degradation that does occur results in the formation of new PFAS compounds, perpetuating the contamination cycle. Consequently, nearly every PFAS molecule ever produced remains present in the environment today.
Health Risks Associated with PFAS Exposure
The health risks posed by PFAS are extensive. Short-chain and ultrashort-chain PFAS, such as trifluoroacetic acid (TFA), are particularly concerning as they can bypass most water filtration systems and infiltrate living organisms. Studies have detected PFAS in the blood, urine, tissues, and organs of humans and animals, with transmission occurring through the placenta, breast milk, and eggs. Health effects linked to PFAS exposure include liver disease, neurological damage, kidney and testicular cancer, and developmental and reproductive complications.
The Cost of Partial vs. Comprehensive Cleanup
The financial implications of cleaning PFAS vary depending on the scope of intervention. Removing only the most concentrated sources of long-chain PFAS in Europe is expected to cost around € 4.8 billion annually. However, tackling short-chain and ultrashort-chain PFAS—compounds that are even more challenging to eliminate—will require an estimated € 100 billion per year, accumulating to € 2 trillion over a twenty-year period.
The Push for PFAS Regulations
In an effort to curb further contamination, five European nations proposed a universal restriction on PFAS under the REACH regulation in February 2023. However, industry lobbying has reportedly sought to weaken or obstruct this proposal. The Forever Lobbying Project claims that numerous industry representatives across multiple sectors have attempted to influence European policymakers to delay or dilute the restrictions.
Additionally, reports indicate that when previous legal and regulatory actions threatened the use of earlier PFAS compounds, the chemical industry responded by developing smaller versions that remain equally persistent and even more mobile, exacerbating environmental and health concerns.
Legislative Steps Toward a PFAS-Free Future
The European Chemicals Agency took a significant step in February 2023 by proposing restrictions on approximately 10,000 PFAS compounds. This move was prompted by projections estimating that around 4.4 million tonnes of PFAS could enter the environment over the next 30 years if current trends continue. To assess the environmental, social, and health impacts of these restrictions, the proposal was opened for review.
Further legislative action followed in April 2024 when the European Parliament voted to prohibit PFAS in food-contact packaging beyond specified thresholds under the Packaging and Packaging Waste Regulation (PPWR). With the regulation now formally adopted, the packaging industry must reduce its use of substances of concern, including certain PFAS compounds.
Conclusion
The immense cost and challenges associated with PFAS cleanup in Europe underscore the urgency of stricter regulations and comprehensive environmental strategies. While legislative progress has been made, the persistent nature of these chemicals and industrial resistance complicate efforts to mitigate their impact. Addressing PFAS contamination will require sustained commitment from policymakers, industry leaders, and environmental advocates to protect public health and the environment for future generations.
