Par où commencer avec les passeports numériques de produits ?
Commencez par ce qu’est un passeport numérique de produit et quelle réglementation s’applique à vos produits, puis déterminez quelles données vous détenez déjà et lesquelles sont chez vos fournisseurs. La plupart des programmes échouent sur la donnée fournisseur plutôt que sur la technologie : cartographiez cet écart avant de choisir une plateforme.
The two regulations that create most passport obligations today are the Ecodesign for Sustainable Products Regulation (EU) 2024/1781, which phases in product group by product group through delegated acts from 2026 to 2030, and the EU Battery Regulation (EU) 2023/1542, whose battery passport becomes mandatory in February 2027.
