The review evaluates conformity with ISO 14040 and ISO 14044 and focuses on methodological consistency, transparency, and documentation quality."},{"q":"What does an ISO 14040\/14044 LCA critical review evaluate?","a":"The review evaluates the study\u2019s goal and scope, functional unit, reference flow, system boundary, allocation methods, data quality, impact assessment, interpretation, and reporting. It assesses how the study was designed, modeled, interpreted, and documented."},{"q":"What deliverables are provided in an LCA critical review?","a":"Deliverables include a structured findings register covering gaps, risks, and non-conformities. DEISO also provides recommendations, methodological and documentation improvements, and an independent technical review conclusion for internal governance and pre-submission readiness."},{"q":"Does DEISO provide panel-based LCA critical reviews?","a":"No, DEISO provides reviews conducted by a single senior LCA expert rather than panel-based critical reviews involving three or more independent experts. Where ISO 14044 requires a panel, such as for public comparative assertions, a qualified external panel must be engaged."},{"q":"Can DEISO review an LCA study it prepared?","a":"No, DEISO does not prepare the LCA study that is subject to its critical review.
