Digital Product Passport: Global Research Trends and Future Orientation

This paper employs bibliographic analysis of the Scopus database from 2003 to 2026, combined with PRISMA filtering, to construct a dataset of 445 publications on Digital Product Passports (DPP). The results show that DPPs are emerging as an interdisciplinary research direction, characterized by significant collaboration (1,314 authors; an average of 3.85 authors/article; international collaboration: 20.9%), with a concentration in publishing channels such as Procedia CIRP, IFAC-PapersOnLine, Sustainability (Switzerland), and European research centers. Network analysis of authors and keywords reveals key themes, including the circular economy, product data digitization and governance, supply chain transparency, and technological trends (such as interoperability, data sharing, digital twin, Industry 4.0, and blockchain), while highlighting barriers to data standardization and information sharing mechanisms within the value chain.
