Starting from 2025, the EU is expected to implement new legislation requiring all products to have a digital product passport, which will provide reliable sustainability data – right down to the smallest component. The ProPare project developed a prototype showing how a global, standardized infrastructure for Digital Product Passports could work in practice. The solution is based on a set of open, competition-neutral, and global standards, and the ambition in the long run is that it will be useable for linking all types of product information and sustainability data to products, regardless of industry, company, or product category. The ProPare project was carried out in a broad collaboration between Axfoundation, the Swedish Trade Federation, Ecolabelling Sweden AB, GS1 Sweden, which is part of the global standards organization GS1, as well as trading companies, brand owners, and technology developers.
