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. 

A quarter of the 100 industrial sites discharging the largest quantities of forever chemicals in France have been supplying the agricultural sector with “sewage sludge” meant to fertilise fields. The toxic fertiliser has been spread over several thousand hectares, Disclose can reveal in partnership with France 3. The French authorities have struggled to take the measure of this health and environmental time bomb.
