Tesco has reportedly agreed to enforce “digital passports” across its clothing range amid a looming sustainability crackdown by the EU.

       Britain’s largest supermarket has announced plans to offer shoppers more detailed information about each item in its F&F fashion range, including the origins of the materials used in the garments.

       This initiative aligns with Brussels' efforts to enhance supply chain transparency through new regulations that will require companies across the eurozone to implement digital product passports (DPPs).

       These rules will obligate businesses selling items ranging from toys and fashion to furniture to disclose detailed information not only about the materials used in their products but also about their environmental impact.

       The scheme has been likened to the introduction of detailed nutritional labeling on food and drinks.

       It will be gradually implemented across different sectors over the next eight years, with campaigners hoping it will help address greenwashing and improve supply chain practices.

       Andrew Xeni, founder of the eco-friendly fashion label Nobody’s Child, which has already tested the "passports", told the Telegraph: “What they’re doing is, in essence, saying consumers should have the right and access to a level of information that enables them to make an informed buying decision, so that they’re aware of the environmental impact of that product that they’re buying.”

       As well as providing greater levels of information, the scheme will be accompanied by new requirements on how companies manage their stock, including a ban on destroying unsold clothing.

       Mr Xeni added it could cause “massive disruption” among fast fashion brands, especially those that have faced scrutiny over sustainability.

       Companies that fail to comply with the legislation could face substantial fines and may even be barred from selling their products in the EU.

       Mr. Xeni, who also operates Fabacus, a tech company specialising in supply chain and data services for digital passports, collaborated with Tesco on the supermarket’s trial.

       Joe Little, head of technical at Tesco, said: “DPPs represent an important step forward, encouraging and promoting sustainable and circular practices.”

       While touted as a boon for consumers, the Government’s European Scrutiny Committee last year raised fears that the DPP scheme could lead to conflicting regulations in Northern Ireland’s because of the Windsor Framework.
