Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).

ISO/TS 14071:2014(E)
Introduction
For life cycle assessment, critical review is the conformity assessment approach according to ISO 14040
and ISO 14044. These standards contain the overarching requirements for critical review in concise
form.
Based on these requirements, a common critical review practice emerged that satisfied stakeholders.
For the mandatory case of life cycle assessment (LCA) studies intended to be used in comparative
assertions intended to be disclosed to the public, the performance of a critical review is established
as key feature for the acceptance of the study by stakeholders. However, even in the broad range of
applications of LCA, for which a critical review is not mandatory, the commissioners of the LCA study
often decide today to perform a voluntary critical review to improve the robustness of their studies and
to increase credibility.
It is one of the key features of critical review that it does not relate to an accreditation scheme, but
ensures quality by making the individual reviewer personally responsible for the work and by giving
priority to the content rather than the form.
Because of the increasing use of LCA itself, as well as the broader application in tools like carbon
footprinting or upcoming labelling initiatives, it is the intention of this Technical Specification to
document the established critical review practice in a more comprehensive way by providing additional
requirements and guidelines for conducting a critical review and the competencies required.
This Technical Specification might be applicable to other standards that require independent review of
LCA-based procedures and information (e.g. ISO 14045, ISO 14025, ISO/TS 14067), but might need to
be adapted to the specific fields of application. Other reference standards can be included in the critical
review process.
This Technical Specification does not apply to critical reviews performed prior to its publication.
TECHNICAL SPECIFICATION ISO/TS 14071:2014(E)
Environmental management — Life cycle assessment —
Critical review processes and reviewer competencies:
Additional requirements and guidelines to ISO 14044:2006
1 Scope
This Technical Specification provides additional specifications to ISO 14040:2006 and ISO 14044:2006.
It provides requirements and guidelines for conducting a critical review of any type of LCA study and
the competencies required for the review.
This Technical Specification provides:
— details of a critical review process, including clarification with regard to ISO 14044:2006;
— guidelines to deliver the required critical review process, linked to the goal of the life cycle
assessment (LCA) and its intended use;
— content and deliverables of the critical review process;
— guidelines to improve the consistency, transparency, efficiency and credibility of the critical review
process;
— the required competencies for the reviewer(s) (internal, external and panel member);
— the required competencies to be represented by the panel as a whole.
This Technical Specification does not cover the applications of LCA (as illustrated in ISO 14040:2006,
Figure 1).

4 Critical review process and tasks
4.1 Defining the scope of the critical review
As stated in ISO 14044:2006, 6.1, the critical review process shall ensure that:
— the methods used to carry out the LCA are consistent with this International Standard;
— the methods used to carry out the LCA are scientifically and technically valid;
— the data used are appropriate and reasonable in relation to the goal of the study;
— the interpretations reflect the limitations identified and the goal of the study; and
— the study report is transparent and consistent.
NOTE “LCA report” and “study report” are used as synonyms and can contain confidential information which
can be excluded from the third-party report, according to ISO 14044:2006, 5.2.
There are several options as to how to perform a critical review for a given study, including the following:
a) the review is performed based on expert review (see ISO 14044:2006, 6.2) or panel review (see
ISO 14044:2006, 6.3);
b) the review is performed concurrently or at the end of the study;
c) the review includes or excludes an assessment of the life cycle inventory (LCI) model;
d) the review includes or excludes an assessment of individual data sets.
The critical review process shall clearly define and document which options have been covered.
The critical review should cover all aspects of an LCA, including data appropriateness and reasonability,
calculation procedures, life cycle inventory, impact assessment methodologies, characterization factors,
calculated LCI and life c
