Tesco is introducing a ‘product passport’ for its clothing

The high street giant is taking steps to ‘boost supply chain transparency with new sustainability rules’. 

According to reports, British supermarket Tesco is introducing digital ‘passports’ for all of its clothing products.

With a simple scan of a QR code printed on each item, users can access detailed information about a product’s materials, manufacturing process, and – most importantly – environmental impact.

The initiative arrives as the EU prepares to crack down on greenwashing, holding companies to stricter standards when making sustainability claims. Tesco’s decision positions it as an early adopter of this transparency push, potentially setting a new benchmark in the fashion industry.

But, is this genuine progress or just sophisticated marketing?

Digital product passports (DPPs) are set to be rolled out across different industries over the next eight years, and will enable brands to give customers more visibility on materials and their environmental impact.

Tesco is hardly the first company to introduce this kind of offering, however. Sustainable companies like jewellery designer Monica Vinader first introduced a DPP in 2022, allowing consumers to trace the journey of its pieces across the entire supply chain.

And a survey from earlier this year found that luxury consumers are also demanding more transparency from brands. According to Vogue, those surveyed expressed a desire to learn about a product’s materials and authenticity – particularly when it came to handbags, watches, and jewellery.

30% of people expected brands like Gucci, Hermès, Prada, Dior and Louis Vuitton to offer DPPs, suggesting that customers are not only willing, but eager to begin adopting this kind of technology.

Tesco is, however, one of the first high street brands to launch this sustainable mechanic – and certainly one of the first supermarket chains.

The retail giant’s new strategy offers consumers a closer look at how their clothes are made, including insights into sourcing and environmental footprints. The hope is that informed customers will make more sustainable choices, prompting suppliers to adopt greener practices.

Given that fashion is responsible for about 10% of global carbon emissions and generates vast quantities of waste, such transparency could drive change in an industry that has been slow to clean up its environmental record.

However, the decision isn’t all down to Tesco itself. Alongside DPPs, new requirements under EU legislation will determine how retailers manage their stock, including a ban on unsold clothes. Firms that fail to follow the rules will receive fines and may be barred from selling products across the EU.

Andrew Xeni, founder of the eco-friendly fashion label Nobody’s Child, which has already tested DPPs after launching them in March, said: ‘What they’re doing is, in essence, saying consumers would have the right and access to a level of information that enables them to make an informed buying decision, so they’re aware of the environmental impact of the product that they’re buying.’

Xeni added that DPPs could mean trouble for fast fashion brands, forcing ‘massive disruption’ in the industry.

Mandatory EU regulations will take effect in 2027, giving brands a few years to adjust to the measures.

Given this legislation is effectively forcing Tesco’s hand, sceptics may argue that the new DPP scheme is little more than window dressing. The fashion industry has long been criticised for paying lip service to sustainability, and it’s certainly possible that digital passports may not deliver the tangible ecological benefits they promise.

While providing information about a garment’s journey through the supply chain is a step towards transparency, it doesn’t necessarily mean the product is sustainable.

For example, a dress made from recycled polyester might be branded as eco-friendly, but that doesn’t negate the fact that producing synthetic fabrics adds to microplastic pollution and consumes large amounts of energy.

Similarly, a garment might use organic cotton, but this tells consumers nothing about the water usage or working conditions involved in its production.

Simply put, transparency does not necessarily equal sustainability.

The complexity of global supply chains adds to the scepticism. Tracing every step of a product’s lifecycle, from raw material to retail, is a challenge, particularly when suppliers and manufacturers are spread across multiple countries with different environmental and labour standards.

Without independent verification of the data behind these digital passports, there’s a risk that they could become another tool for greenwashing – offering the appearance of accountability without requiring companies to make significant changes to their operations.

The consumer response is also uncertain. While greater transparency is generally welcomed, it remains to be seen whether it will lead to more sustainable purchasing decisions. Fast fashion is popular because it’s cheap and convenient, and most shoppers still prioritise price over the planet.

The demand amongst luxury consumers for DPPs could also be put down to concerns over authenticity – rather than sustainability.

Still, Tesco’s digital passports represent an intriguing development for those focused on improving the planet.

The fashion industry is under growing pressure to substantiate its sustainability claims, and digital passports could help establish a standard for how companies communicate their environmental impact. If widely adopted, this could lead to a more transparent and responsible fashion sector – at least in theory.

Tesco’s passports may offer a new level of visibility into the supply chain, but they must be paired with real efforts to reduce carbon emissions, improve labour conditions, and minimise waste if they are to make a substantive difference.
