The upcoming EU legislation will require nearly all products on the EU market to have Digital Product Passports (DPP). These will provide data on product content and sustainability performance throughout the product’s life cycle, enabling consumers and businesses to make sustainable choices. The ProPare project developed a prototype showing how a global, standardized infrastructure for DPP could work in practice, using a set of global, open, and competition-neutral standards. The project has proven that the solution works to ensure trustworthy product data for all users, sourced in real time from the third-party certifier and the brand owner. With a common language used to identify every single unique product on the market, and a resolver pointing to the right data sources, product data is displayed in a demo-app in real-time, deriving information from multiple, decentralized sources. matter the user, industry, or product category. The report explains why global standards are needed when implementing the DPP.
