French lawmakers have unanimously recognised that the state shares responsibility for the prolonged use of chlordecone in Guadeloupe and Martinique, despite earlier health warnings. The new law commits France to decontaminate polluted soil and water and to compensate victims. Research cited by ANSES shows nearly 90% of island residents have been contaminated, with links to prostate, stomach and pancreatic cancers and other systemic harms. A Paris court will soon consider whether to reopen a criminal investigation into the scandal.
France Acknowledges State Role in West Indies Chlordecone Scandal — Law Pledges Cleanup and Compensation

French lawmakers on Tuesday formally recognised that the state bears part of the responsibility for allowing the toxic pesticide chlordecone to be used in the French West Indies despite repeated health warnings, causing lasting environmental and human harm in Guadeloupe and Martinique.
What Happened
Chlordecone (also sold under brand names such as Kepone) was widely applied on banana plantations in Guadeloupe and Martinique from 1972 until 1993 to combat weevil infestations. Although France banned chlordecone on the mainland in 1990, its use continued in the Caribbean territories for several more years. The Stockholm Convention on Persistent Organic Pollutants later banned chlordecone worldwide in 2009.
Parliamentary Action
On Tuesday evening the French lower house voted unanimously in favour of a bill in which "the state acknowledges its share of responsibility for the health-related, moral, environmental and economic harm suffered by the territories of Guadeloupe and Martinique and by their populations" as a result of the pesticide's prolonged use. The Senate had already approved the measure.
Health and Environmental Impact
Research cited by France's ANSES health agency indicates nearly 90% of residents in Martinique and Guadeloupe have been contaminated with chlordecone. The chemical has been linked to elevated rates of prostate cancer — among the highest worldwide in the two islands — as well as to stomach and pancreatic cancers. ANSES also cites studies showing adverse effects on the nervous system, reproductive health, the endocrine system and the function of organs including the heart. A 1979 World Health Organization report found chlordecone to be "carcinogenic in mice and rats" and judged it reasonable to consider it a carcinogenic risk to humans.
Commitments and Next Steps
The new law sets an official objective for the state to "decontaminate soil and water polluted" by chlordecone and to "compensate all victims of this contamination" in Guadeloupe and Martinique. Socialist lawmaker Elie Califer, who introduced the bill and is from Guadeloupe, described the compromise as a step toward "restoring deeply damaged trust," while warning that further work will be needed to ensure full and fair reparations. Olivier Serva, another MP from Guadeloupe, said he remained "not entirely satisfied" but welcomed the formal acknowledgement of state responsibility.
"This compromise text will help restore deeply damaged trust," said Elie Califer.
Legal Context and Historical Background
The Paris appeal court is expected later this month to decide whether to reopen a criminal investigation into the scandal after Paris magistrates dropped the case more than three years ago, citing the difficulty of securing convictions because of the passage of time. The parliamentary vote follows broader efforts in the same legislature, including the repeal of outdated slavery-related legislation that had never been formally annulled despite slavery's abolition in 1848. Activists and officials say the islands continue to feel long-term injustices tied to colonial-era policies and persistent inequalities with mainland France.
Authorities now face the practical challenge of mapping contamination, funding long-term remediation, and delivering compensation and health support to affected communities. The law is a significant symbolic and legal step, but implementation will determine whether it delivers meaningful redress and environmental recovery for Guadeloupe and Martinique.
