I delivered a masterclass on ‘Digital Product Passport: What it Means for You | Exploring the Digital Product Passport initiative under the Ecodesign Regulation’ to the students of the Institute of Sustainability Studies in May 2025. I introduced the concept of the Digital Product Passport (DPP), explaining it as a comprehensive digital record that tracks a product's lifecycle and stores essential data regarding materials, carbon footprint, and end-of-life instructions via methods like QR codes or blockchain. This initiative is designed to increase transparency, traceability, and sustainability across supply chains, enabling customers to make better choices and helping businesses achieve cost savings through efficiency. The DPP is the core mechanism of the European Union’s Ecodesign for Sustainable Products Regulation (ESPR), which aims for full operability by July 2026, starting with delegated acts targeting key sectors like batteries and textiles. The lecture outlined practical five-step action plans, urging businesses to focus on supply chain digitization and prototyping while preparing for challenges related to standardization and adoption costs, particularly for SMEs. Ultimately, the DPP was presented as a crucial policy shift intended to combat waste and hold producers accountable for environmental claims.
