GS1 case study: Behind the seams: Digital insights in socks
How a pilot project brought the Digital Product Passport to life
The European Union’s Regulation on Ecodesign for Sustainable Products1 (ESPR) is set to reshape the way physical goods are designed, made and consumed.
Covering a range of physical goods categories, the regulation aims to make products more durable, circular and energy-efficient across their entire lifecycle.
At the heart of this initiative is the Digital Product Passport (DPP): a digital record that contains detailed information about a product. It serves as a digital
identity for the product, offering traceability and transparency throughout its lifecycle—from design to disposal—by making key information about materials,
production and environmental impact digitally accessible. To see how this could work in practice, a pilot was launched to test the concept on an unexpected but essential item: socks.
