Expansion of the Zero Discharge of Hazardous Chemicals (ZDHC) partnership – which has a target date of 2020 - is “crucial” if it is to have a major effect on the industry, according to the initiative’s latest report.

So far, Adidas, C&A, H&M, Li Ning, Nike and Puma have signed up to the target, joined more recently by G-Star Raw, Levi Strauss & Co and Jack Wolfskin.

The latest ZDHC report said members were “well under way” towards achieving a foundation to work towards the 2020 target, with members working to structure and clarify the programme.

A Joint Roadmap on the issue has a firm publishing deadline of May next year, the partners said.

But they added: “Expansion of ZDHC participation is crucial in order to tackle the complex issues involved and to lift these challenges from a few industry leaders to the entire industry.

“Towards that effort, we re-emphasise our warm welcome for any interested brands, retailers, suppliers, chemical industries, and stakeholders who would like to be involved in our ZDHC programme.”
