As part of the ESPR, the first delegated act is expected within the next year and will begin with the iron and steel industry- cornerstones of the built environment vertical- before expanding to other construction products. DPPs will require manufacturers and suppliers to provide product-level data on material composition, carbon footprint, repairability, and end-of-life handling.
In the same vein, to further ensure sustainability measures are met within the built environment, the proposed amendments to the CPR ensure that performance declarations, CE markings, and other construction-specific data are contained within construction product DPPs alongside the EPSR’ s information requirements.
Together, these shifts signal the arrival of verified sustainability in construction: a landscape where claims about low-carbon materials, circularity, and compliance must be backed by auditable data. For contractors, developers, and product manufacturers
preparing for 2026, two priorities are becoming clear- proof must become central to eco-claims, and a construction business’ audience is just as integral
Proof must become central to all environmental claims
As scrutiny around greenwashing intensifies, construction firms should assume that every environmental claim will be challenged. That pressure exposes a long-standing weakness in the sector: fragmented data spread across material suppliers, fabricators, contractors, and logistics partners. Embodied carbon figures, recycled content claims, and durability data are often inconsistent or poorly documented.
DPPs are intended to address this gap. They create a structured, digital record of a product’ s attributes across its lifecycle- from raw material extraction and manufacturing through installation, maintenance, reuse, and end-of-life. For construction products, this will underpin claims around low-carbon steel,
