The European Union is moving from environmental declarations towards structured, product-level data. For construction products, the revised Construction Products Regulation provides the sector-specific framework for a Digital Product Passport (DPP), aligned with the wider Ecodesign for Sustainable Products Regulation. For precast concrete producers, this development is both a compliance challenge and a strategic opportunity. The sector already benefits from controlled factory production, repeatable processes, and a growing base of Environmental Product Declarations. Its main difficulties are product variability, upstream data gaps, life-cycle assessment costs, and the integration of supply chain information. This article uses a SWOT analysis to examine these factors and discusses carbon-footprint calculation, green-claims risk, and the careful treatment of concrete carbonation. It concludes with a practical implementation route: build verified, version-controlled environmental data now, before the passport becomes a routine market requirement.
