Levi’s, the world’s largest denim brand, has committed to eliminate all releases of hazardous chemicals throughout its entire supply chain and products by 2020, following public pressure in response to Greenpeace’s global Detox campaign.

“Now more than ever, we are seeing brands such as Levi’s listen to the groundswell of support for toxic-free fashion,” said Greenpeace Toxics Campaigner John Deans. “Now it’s  time for other brands such as Calvin Klein, Gap, and Victoria’s Secret to  follow Levi’s lead and end their toxic addiction. We’ll continue to expose brands until the use – and abuse – of hazardous substances is totally eliminated.”

As part of its commitment, Levi’s will begin requiring 15 of its largest suppliers (each with multiple facilities) in China, Mexico and elsewhere in the Global South to disclose pollution data as early as the end of June 2013. This will be followed up with a further 25 major suppliers by the end of 2013, meaning those living near all these facilities gain crucial access to information about discharges into their local environment.

Levi’s commitment comes just eight days after Greenpeace launched its report “Toxic Threads: Under Wraps” in Mexico City on December 5th. Since then, over 210,000 people joined the campaign calling on Levi’s to Detox, with tens of thousands taking action on Facebook and Twitter. Over 700 people have protested outside Levi’s shop fronts in over 80 cities worldwide, including a demonstration yesterday in front of the company’s headquarters in San Francisco.

“Levi’s has become a global Detox leader now that it has promised to use alternatives to hazardous chemicals and make their supply chain transparent. This is a milestone in the way clothes are manufactured and a victory for people in Mexico and elsewhere who are affected by toxic water pollution every day,” added Greenpeace Mexico Toxics campaigner, Pierre Terras.

Levi’s becomes the eleventh brand to make a credible commitment to eliminate releases of all hazardous chemicals throughout its supply chains and products since Greenpeace launched its Detox campaign in 2011. A key part of the commitment is Levi’s elimination of all PFCs by the end of 2015, and a promise to lead on the adoption of PFC-free alternatives and non-hazardous chemicals by 2015.

Greenpeace’s Detox campaign demands fashion brands commit to zero discharge of all hazardous chemicals by 2020 and require their suppliers to disclose all releases of toxic chemicals from their facilities to communities at the site of the water pollution.
