Following a year-long investigation, Greenpeace activists protested outside the world’s largest Adidas store in Beijing, and a nearby Nike store, to draw attention to the claimed release of hazardous chemicals from two textile processing facilities in China.

The environmental pressure group said it had found the toxic chemicals in samples of waste water discharges from the Youngor Textile City Complex and the Well Dyeing Factory, by the Yangtze and Pearl River deltas.

The facilities supply apparel companies including Adidas, Nike, PVH, Puma, Abercrombie & Fitch, Calvin Klein, Lacoste, Li Ning, Meters/bonwe, Bauer Hockey, Converse, Cortefieland H&M, Greenpeace added.
