The Declaration of Performance (DoP) must now include environmental data in addition to technical characteristics. This means carbon footprint, energy consumption, recyclability, and other environmental indicators become mandatory for CE marking. Manufacturers must produce environmental reports (e.g., based on EN 15804) for each product.

The DPP is formally introduced as a requirement. It is a digital repository containing all technical and environmental data of the product, accessible via QR code or web link. This passport ensures digital traceability throughout the supply chain. Companies must implement IT systems (databases, web links, QR integration, BIM compatibility) to generate and provide mandatory DPPs, especially for priority product categories.

The new CPR imposes stricter environmental criteria. Products must meet meta-criteria for circularity and sustainability, such as reparability, recyclability, and reduced climate impact. Specific indicators will be required (CO₂ emissions, use of recycled materials, hazardous substances) for priority materials like concrete, steel, and insulation. Companies will need to reformulate many products and document their environmental performance.

Although current European standards remain valid during the transition, the regulation foresees gradual revision and issuance of new harmonized standards for each product family. These will include the new essential environmental performances defined in the regulation’s annex. Manufacturers and laboratories must follow existing specifications and new versions in parallel until the latter enter into force.

Compliance control across the EU is reinforced. Greater documentary transparency is required (including DPP and EPD), and more severe sanctions are established for non-compliance. In practice, authorities in each Member State will monitor that manufacturers and importers comply with the new mandatory data in CE marking, significantly increasing corporate responsibility.
