ISO 14040/14044: Framework, Requirements and Review
What this domain tests
This domain tests the distinction between ISO 14040 and ISO 14044 and the procedural requirements that make an LCA defensible: goal and scope, inventory, impact assessment, interpretation, reporting, and critical review.
Core rules and concepts
- ISO 14040 sets principles and framework. ISO 14044 sets requirements and guidelines for the same four phases.
- The standards do not mandate one LCIA method, one database, or one allocation rule. They require transparency, consistency, and justification.
- Reporting must cover goal and scope, inventory, impact assessment, interpretation, limitations, and data quality.
- Critical review is required for comparative assertions disclosed to the public. A review panel normally includes interested parties and must examine method, data, and conclusions.
- ISO 14044 is not a management-system standard; certification claims should not be confused with conformity to the LCA requirements.
Worked example
A company wants a public claim that Product A has a lower carbon footprint than Product B. The study uses a proprietary dataset and no external review. Under ISO 14044, the comparative assertion disclosed to the public triggers critical review by a panel with relevant expertise and interested-party representation. The panel checks functional equivalence, boundary consistency, allocation, LCIA version, and whether the conclusion follows from the inventory. Without that review, the comparison is not ready for public use even if the calculation is internally consistent.
Traps that cost marks
- Treating ISO 14040 as a prescriptive checklist of calculation rules.
- Claiming ISO 14044 compliance while omitting critical review for a public comparison.
- Using ISO 14067 or ISO 14025 as a substitute for the 14040/14044 framework.
- Hiding methodological choices instead of justifying them in the report.
