- Global
ISO 21930 can be used by organizations such as construction product manufacturers, EPD programme operators, architects, engineers, builders, and supply-chain sustainability teams who develop or rely on ISO-aligned EPDs in procurement, certification systems (e.g., LEED, BREEAM), or regulatory frameworks.

Introduction
ISO 21930:2017, titled Sustainability in buildings and civil engineering works — Core rules for environmental product declarations of construction products and services, provides the foundation for EPDs used in the building and infrastructure sectors. As a “core product category rules (PCR)” document, it establishes how life-cycle assessment data, impact indicators, life-cycle stages, and required content are structured in an EPD for construction goods and systems.
The standard complements the general Type III EPD principles in ISO 14025 by focusing specifically on construction materials and services and by prescribing consistent rules for boundary setting, modular life-cycle reporting, and environmental indicators that must be included.
What ISO 21930 asks
ISO 21930 does not mandate EPD creation by law, but it defines the methodological baseline for credible EPDs in construction, including:
Core PCR framework: ISO 21930 establishes the baseline requirements that Product Category Rules must follow when developing construction product EPDs. It lays out rules for life-cycle inventory (LCI), impact assessment (LCIA), and modular life-cycle stages (e.g., raw material, manufacturing, transport, use, end of life).
Life-cycle stage definitions: The standard describes which processes and stages are to be included in a life-cycle assessment and how they should be subdivided into information modules for transparent EPD reporting.
Scenario rules: It defines how to set and document scenarios such as end-of-life or use-stage conditions that affect LCA results.
Core EPD elements: ISO 21930 specifies the environmental indicators, data quality requirements, technical information, and documentation structure that must appear in a construction EPD. This includes rules on comparability and conditions under which products can be compared based on EPD data.
Together with ISO 14025, ISO 21930 ensures that construction EPDs are consistent, verifiable, and meaningful across products and regions.
Status & Outlook
ISO 21930:2017 is the current edition (second edition) and remains valid after review, underpinning most international frameworks for construction EPDs worldwide. It has been confirmed through ISO’s periodic review process, meaning it continues to be recognised as the authoritative core EPD rules for construction products and services.
The standard forms the backbone of many regional and national EPD programmes and is accepted in green building certification systems and public procurement requirements, enabling manufacturers to demonstrate environmental performance consistently across borders.
As global construction markets increasingly prioritise embodied carbon and life-cycle transparency, ISO 21930’s role is likely to remain central, often working in concert with regional PCRs (Product Category Rules) and sector-specific adaptations that refer back to its core requirements.
