The European Commission (DG GROW) published a draft standardisation request (standardisation mandate) addressed to CEN to revise/draft harmonised standards for precast concrete products under the Construction Products Regulation framework. The draft explicitly links environmental sustainability essential characteristics to lifecycle assessment and Product Category Rules (PCRs) and references EN 15804:2012+A2:2019+AC:2021 as the methodological basis for environmental declarations in this context. The document includes a feedback deadline (3 March 2026) and indicates intended target dates (e.g., annex tables referencing 30 Oct 2026) for delivery/adoption of standards. For EPD/EN 15804 compliance teams (especially construction product manufacturers), this is an early but actionable signal that future harmonised product standards may embed EN 15804-aligned environmental declaration mechanics (via PCRs and required indicators) into EU product documentation (e.g., DoP/DoPC workflows) once finalized and implemented.
