Decathlon’s target is 100% sustainable cotton for Decathlon textile products. The company addresses the elimination of highly hazardous pesticides, water use reduction, and biodiversity restoration mostly through its membership of the Better Cotton Initiative. The company collects end-of-life clothing and has introduced several other initiatives to support recycling. Human rights and labour issues are addressed through Better Cotton Initiative.

The company significantly improved its sustainable cotton uptake 76% in 2018 - including 69% Better Cotton, 6% organic and 1% recycled cotton. In total the company used 21,787 metric tonnes of sustainable cotton.

Decathlon does not publish information on the absolute volume and origin of cotton used in its products. The company does not provide information on its suppliers (finished product, fabric manufacturers, yarn spinners).
