Investigation into the trade secrets of the most popular retailer in France
A year-long investigation into the heart of the Decathlon system. Confidential documents and unpublished employee testimonies uncovered by Disclose reveal the serious human and environmental consequences of the French sports giant’s low-cost strategy.
The factory that produces the most pollution in France is using more coal than ever. In August 2025, ArcelorMittal Dunkirk took delivery of several thousand tonnes of coal from an extremely toxic mine in Mozambique. Some residents of the town of Moatize have been exposed to serious air pollution and seen their homes destroyed by blasts, an investigation by Disclose and Socialter can reveal.
PFAS have contaminated everything in 17 municipalities in the Ardennes and Meuse departments in northeast France, from soil to vegetables, rivers, fish and even people’s bloodstream, Disclose and France 3 can reveal. Tests conducted with a Montreal University laboratory show record levels of ‘forever chemicals’ in agricultural land. The pollution poses a “direct threat to health” according to a “restricted” memo.
