Global clothing production doubled between 2000 and 2017 and brands such as Zara, H&M, Nike and Adidas have expanded their supply chains to keep up with demand.

Textile manufacturing uses enormous quantities of dyes, additives and stabilisers, which then enter the environment through wastewater. 25 per cent of global chemical output is used in the textile industry, and 42 per cent of that usage is in China.

The first step companies are asked to take is to set up a Manufacturing Restricted Substances List.
