The Digital Product Passport (DPP) is one of the many initiatives that the European Union is promoting within the scope of the European Green Deal, which aims to achieve carbon neutrality by 2050 and reduce CO2 emissions to 55% by 2030, compared to 1990 levels. In this framework, the European Commission has proposed several initiatives to prevent waste, to reuse materials within the value chain for the maximum possible period, stimulating circularity, and to promote sustainable consumption. It is in this context that the DPP emerges, being currently analysed for three value chains: textiles, batteries and electronic products. Thus, by 2030, all textile products sold in the European Union will need a digital product passport, which will consist of a label with a QR code (or another tag that allows the unequivocal identification of the product), allowing to view information about the origins of the product, the composition of the material, the supply chain, the sustainability index (and possibly the specific consumption of water, energy and chemicals), as well as its recyclability and additional information on conservation and cleaning, all in a single identifier (Fig. 1).
