Lawyer Fights Chemical Giants for France's 'Chemical Valley'
24 Aug
Summary
- Hélène Duguy is suing companies for Pfas pollution near Lyon.
- Pfas chemicals are linked to severe health issues and persist for years.
- Duguy previously advised these companies on environmental regulations.

Hélène Duguy, a lawyer with a personal connection to France's "Chemical Valley" south of Lyon, is spearheading legal action against companies accused of Pfas pollution. Having grown up near these factories, Duguy understands the tangible impact of invisible chemical contamination on local communities. Her mother, who previously trusted local authorities, is now considering selling her home due to concerns over homegrown food and local produce safety.
Duguy, now with the environmental organization ClientEarth, is using litigation as a strategic tool to hold polluters accountable and compel regulators to act. Pfas, or "forever chemicals," are pervasive and linked to serious health issues such as cancer and birth defects. ClientEarth has previously targeted major corporations and is now focusing on the chemical industry's role in widespread contamination across Europe.
Her previous work at a law firm advising chemical companies on environmental law provides her with unique insight into corporate strategies. This experience, combined with her network of European environmental lawyers, strengthens her ability to challenge systemic pollution. Duguy's aim is to achieve real-world accountability before irreversible damage occurs, transforming complex legal battles into tangible change for affected communities.
