What Is ISO 21930? Understanding the Sustainability Standard for Construction
ISO 21930 is the international building sustainability standard titled “Sustainability in buildings and civil engineering works – Core rules for environmental product declarations of construction products and services.” Developed by the International Organization for Standardization, ISO 21930 outlines how to consistently assess and report the environmental performance of building materials and construction products. Its main objective is to provide reliable, transparent guidelines for measuring environmental impacts across the entire life cycle of buildings and infrastructure.
- Defines the core rules for creating Environmental Product Declarations (EPDs) for construction products and services
- Establishes a methodology for evaluating the eco-friendliness of building materials, from raw material extraction through disposal or recycling
- Supports consistent, comparable sustainability assessments across global construction markets
- Aligns with sustainable construction guidelines and construction standards for low carbon projects
ISO 21930 serves as a foundational reference for organizations aiming to meet stricter regulations, achieve net-zero targets, and respond to growing demand for sustainable construction. The standard is especially relevant for manufacturers, retailers, and supply chain managers who must demonstrate environmental compliance and provide verified data to stakeholders. By setting a universal method for environmental product declarations, ISO 21930 drives accountability and transparency, making it a cornerstone for sustainable development in the construction sector.
ISO 21930 Environmental Product Declaration Guidelines: Core Rules and Structure
Environmental Product Declarations (EPDs) are standardized documents that communicate the environmental impact of building materials and products across their life cycle. ISO 21930 provides the environmental product declaration guidelines that define how EPDs should be created, interpreted, and reported in the construction sector. EPDs built on this green building environmental standard give manufacturers, supply chain managers, and stakeholders consistent, comparable insights into the eco product declaration process.
ISO 21930 mandates that EPDs cover all life cycle stages – raw material extraction, manufacturing, use, and end-of-life – so that every declaration of building materials impact is transparent and complete. Product Category Rules (PCRs) are central to this process, setting out the specific requirements and calculation rules for different product groups within the standard.
- Identify the relevant Product Category Rules (PCRs) for the product group.
- Gather and verify life cycle data for the product, covering raw materials to disposal or recycling.
- Conduct a life cycle assessment (LCA) following the guidance in the PCR and ISO 21930.
- Compile the EPD, ensuring all required environmental indicators and data are reported clearly.
- Have the EPD independently verified to guarantee transparency, accuracy, and credibility.
Following this structure ensures environmental declarations are reliable and comparable across projects, suppliers, and regions. The ISO 21930 framework builds trust in sustainable construction by making environmental reporting more robust and actionable for regulatory compliance and supply chain transparency.
How ISO 21930 Supports Sustainable Construction and Regulatory Compliance
ISO 21930 sets a benchmark for sustainable construction environmental criteria by providing a structured approach to environmental reporting and eco‐compliance building regulation. This standard enables construction companies, manufacturers, and supply chain managers to evaluate, report, and actively reduce their carbon footprint according to global sustainability goals. By requiring detailed, verified data on environmental impacts, ISO 21930 ensures that all stakeholders – contractors, developers, and regulators – can access transparent, comparable information that supports regulatory framework for eco buildings and sustainability compliance accreditation.
Using ISO 21930, organizations can streamline documentation for green building certifications such as LEED and BREEAM, and meet the strict reporting requirements of frameworks like the Corporate Sustainability Reporting Directive (CSRD). The standard’s alignment with these widely recognized systems simplifies the process of demonstrating compliance and accelerates progress toward net-zero and sustainable development in construction. This results in improved supply chain transparency, better risk mitigation, and a strong foundation for meeting future environmental regulations.

Life Cycle Assessment Methodology in ISO 21930
ISO 21930 incorporates a rigorous life cycle assessment methodology to provide a comprehensive eco product lifecycle analysis for building materials. Every construction material undergoes a detailed evaluation of its environmental impacts from raw material extraction to end-of-life, including energy consumption, resource use, manufacturing, transportation, installation, operation, and final disposal or recycling. This transparent approach to LCA for building materials forms the backbone of reliable construction material eco assessment and helps manufacturers, supply chain managers, and regulators pinpoint carbon hotspots and prioritize reduction strategies.
By requiring transparent, verified data collection at every product stage, ISO 21930 ensures that environmental impacts are not just measured, but fully understood and actionable. LCA for building materials is central to meeting both regulatory and market demands for sustainability, supporting companies in achieving compliance with international standards and providing the data foundation for trusted environmental product declarations.
