Independent ISO 14040/14044 critical review and pre-submission audit of Life Cycle Assessment studies prepared by your organization or its advisors. Strengthen methodological defensibility, ensure transparency, and improve readiness for comparative claims, EPD development, procurement documentation, and high-stakes public disclosures.

This engagement covers only the independent critical review and pre-submission audit of your existing Life Cycle Assessment study.
Where DEISO provides LCA modeling services, such services are contracted separately and are never performed on the study subject to critical review.

LCA Critical Review (ISO 14040 / ISO 14044)

Independent Technical Review, Editing & Pre-Submission Audit of LCA Studies

Life Cycle Assessment (LCA) results are increasingly used in procurement decisions, public sustainability claims, product declarations, and tender documentation. In these contexts, credibility depends on whether the study is methodologically defensible, transparent, and aligned with ISO requirements. If your organization has prepared an LCA study (internally or with an appointed consultant), DEISO provides Independent LCA Critical Review to evaluate conformity with ISO 14040 and ISO 14044 and to strengthen readiness prior to publication, comparative assertions, or program operator submission. To preserve independence, DEISO does not prepare the LCA study subject to review and does not act as a verification or certification body. Our role is limited to independent technical review, editing, and pre-submission audit to improve readiness before formal third-party processes (where applicable).

Scope Limitations & Service Boundaries

No Panel Review Services — DEISO does not provide panel-based critical reviews (three or more independent experts). Where ISO 14044 requires a panel (e.g., for public comparative assertions), clients must engage a qualified external panel.
Single Independent Expert Review Only — All reviews are conducted by a single senior LCA expert. This is compliant with ISO 14044 for non-comparative studies or studies not intended for public comparative assertions.
Not a Verification or Certification Body — DEISO does not issue verification statements, certifications, or approvals and does not act as a program operator.
No EPD Verification or Issuance — DEISO does not verify Environmental Product Declarations (EPDs). Our role is limited to technical review and pre-submission readiness support.
No Regulatory or Legal Approval Authority — The critical review does not constitute regulatory approval or formal compliance certification.
Technical and Methodological Scope Only — The review focuses strictly on ISO conformity, methodological consistency, transparency, and documentation quality. It does not replace third-party verification where required.
Client Responsibility for Disclosure — The client remains responsible for how results are used, communicated, and whether additional review (e.g., panel review) is required under ISO or program operator rules.

When an LCA Critical Review Is Required or Strongly Recommended

Public or internal comparative assessments (subject to ISO conditions)
EPD development support where a critical review is expected by the program operator or internal governance
High-stakes procurement, tender, or supplier qualification processes
Investor- or board-level sustainability disclosures
Studies involving complex allocation, multi-site systems, or mixed data quality

What an ISO 14044 Critical Review Evaluates

A critical review evaluates whether an LCA study is consistent with ISO principles, requirements, and methodological expectations. It is a structured technical assessment of how the study was designed, modeled, interpreted, and documented.

Core Review Dimensions

Goal and scope — stated purpose, intended audience, and decision context
Functional unit and reference flow — clarity, appropriateness, and consistency
System boundary — inclusions, exclusions, and transparency of assumptions
Allocation methods — methodological justification and handling of multi-output processes
Data quality — representativeness, consistency, and documentation sufficiency
Impact assessment — method selection and category consistency
Interpretation — validity of conclusions and disclosure of limitations
Reporting — transparency, reproducibility, and auditability

Critical Review Deliverables

Structured findings register (gaps, risks, and non-conformities)
Actionable recommendations aligned with ISO 14040/14044
Methodological and documentation improvements
Independent technical review conclusion for internal governance and pre-submission readiness

Critical Review vs Pre-Submission Audit — Strategic Difference

Organizations often require two support modes: (1) formal methodological evaluation (critical review) and (2) practical readiness improvement before submission (pre-submission audit and editing). DEISO provides both while maintaining strict independence. INSERT THE LCA COMPARISON TABLE BLOCK HERE

Critical Review vs Pre-Submission Audit — Detailed Comparison

Dimension	LCA Critical Review (ISO 14040/14044)	LCA Pre-Submission Audit & Editing
Primary Objective	Assess methodological conformity and defensibility	Improve readiness and reduce corrective cycles before submission
Main Focus	ISO alignment, methodological rigor, transparency	Completeness, consistency, clarity, submission readiness
Testing Depth	Methodology-first evaluation and consistency checks	Practical gap fixing, narrative tightening, evidence organization
Best Fit	Comparative claims, public disclosures, high-stakes decisions	EPD/PCF submissions, internal governance, procurement readiness
Typical Output	Independent critical review conclusion and findings register	Audit findings register + edited narrative + corrective action guidance
Role of DEISO	Independent technical reviewer	Independent technical auditor/editor prior to external submission
