Overview
EN ISO 14044:2006/A2:2020 is Amendment 2 to ISO 14044 (2006) - the international standard that sets requirements and guidelines for life cycle assessment (LCA) within environmental management. Published by CEN in October 2020, this amendment updates terminology, clarifies scope and inputs, and adds a new informative annex on allocation procedures to help practitioners apply consistent, transparent LCA methods.
Key Topics and Requirements
- Updated definitions: Core terms such as life cycle, system boundary, completeness check, consistency check and sensitivity check are revised to clarify intent and align interpretation across studies.
- Clarified inputs: The standard explicitly notes inputs can include resources (water, biomass, metals), services (transportation, energy supply) and ancillary materials (lubricants, fertilizers).
- Allocation guidance: A new Annex D explains allocation procedures in detail:
- Use of system expansion (aka system boundary expansion) to avoid allocation by substituting co-products with functionally equivalent systems.
- Physical allocation when causal relationships exist and co-product outputs can be independently varied.
- Treatment of recycling credits and considerations for recycled vs primary materials.
- Strengths, weaknesses and practical limitations of different allocation approaches.
- Editorial updates: Small changes to table headings (e.g., “Use stage”) and cross-references (Annex D referenced in allocation clause).
- Applicability: The amendment was endorsed by CEN and required national adoption (or endorsement) by April 2021 in member countries.
Applications and Who Uses It
EN ISO 14044:2006/A2:2020 is used by:
- LCA practitioners and consultants performing product or process LCAs.
- Corporate sustainability teams preparing environmental footprints and decision-support analyses.
- Product designers and R&D assessing environmental trade-offs during design.
- Regulators and policy makers referencing standardized LCA methods for ecolabelling, green public procurement or product policy.
- Auditors and certification bodies verifying consistency and transparency in LCA studies.
Practical uses include conducting robust LCAs, choosing and documenting allocation methods for multi-output systems, calculating recycling credits, and ensuring study consistency and completeness aligned with ISO/EN requirements.
