Method
Critical review
Also: ISO 14044 critical review · LCA critical review · panel review
The independent review process defined in ISO 14044 that checks whether an LCA study is consistent with the standard's methodology, data, interpretation and reporting requirements; a panel review is required for comparative assertions disclosed to the public.
A critical review is the quality-assurance mechanism built into life cycle assessment. Its purpose is to ensure that the methods used are consistent with ISO 14044, scientifically and technically valid, that the data are appropriate and reasonable in relation to the goal, that interpretations reflect the limitations identified, and that the report is transparent and consistent.
Types of review
ISO 14044 distinguishes between a review by an internal or external expert and a review by a panel of interested parties. When an LCA supports a comparative assertion intended to be disclosed to the public, a panel review is required, with a chair who is an independent external expert.
Relationship to EPD verification
EPD verification and LCA critical review overlap but are not identical. Verification checks a declaration against a PCR under a programme; a critical review checks a study against ISO 14044 itself. Some programmes accept a critical review as part of verification evidence.
Where Verdatir fits
Verdatir structures the evidence a reviewer needs, checks completeness against ISO 14044 requirements and records reviewer reasoning, so that a critical review is documented as rigorously as the study it examines.

In practice
Verdatir turns the rules behind this term into automated checks with a reviewer in the loop.
