Sustainability information — Part 1: General principles and requirements for validation and verification
This document specifies general principles and requirements for the validation and verification process of sustainability information, including reporting on environmental, social, governance (ESG) and other sustainability aspects. It provides general principles and requirements for determining the categorization of quantitative and qualitative information. These principles and requirements contribute to the set of rules and procedures that are provided in validation/verification programmes. This document can also be used as the basis for validation and verification activities that support other conformity assessment schemes. NOTE: This document can be applied by validation and verification bodies according to ISO/IEC 17029. It can contribute to schemes operated by inspection bodies according to ISO/IEC 17020 or certification bodies according to ISO/IEC 17065.

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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.

Introduction
0.1  With increasing public demand and advancing legal provisions (regulatory and contractual) for
declarations, disclosures and reporting of sustainability information, there is a significant market need for the
validation, verification and assurance of this information.
0.2  Standards are needed for both:
a) identifying metrics and indicators, monitoring, compiling, reporting, declaring and disclosing information
about sustainability matters (including environmental, social and governance (ESG) matters);
b) harmonized approaches to validation/verification and assurance of that information.
Validated and verified sustainability information can be used for decision-making, including investment
decisions, procurement decisions, or individual choices during consumer purchasing, the use of services and
decisions on where to work.
0.3  In this document, the sustainability information that is declared by a responsible party is the object of
the validation or /verification. Validation and /verification bodies assess the declared sustainability
information for its conformity with, and fulfilment of, ‘specified requirements and criteria’criteria.
0.4  Specified requirements and criteria are set by a validation/verification programme, which can be a
mandatory regulatory reporting programme, or a voluntary programme for a specific sector or sustainability
matter. The result of a completed validation/verification can be the provision of an assurance opinion which
attests that:
a) the specified requirements and criteria have been fulfilled;
b) the reasonableness of the assumptions, limitations and methods that support declared sustainability
information about a future outcome has been validated;
c) the material correctness and fair representation of historical data and information has been verified.
NOTE The primary outcome of validation/verification activities in accordance with the ISO 14019 series is an
assurance opinion. In addition, the ISO 14019 series allows for alternative non-assurance outcomes or deliverables. The
deliverable chosen for each specific validation/verification activity (i.e. an assurance opinion or a non-assurance
deliverable) is specified in the relevant validation/verification programme and confirmed between the
validation/verification body and its client in a specific engagement agreement. Non-assurance deliverables include
reports of factual findings based on agreed-upon procedures (AUP) reports, findings reports and evidence reports. These
non-assurance deliverables can be appropriate for situations where an assurance opinion is not required (e.g. in
voluntary or internal reporting, reporting from organizations upstream or downstream in the value chain, for small and
medium-sized enterprises (SMEs), in situations where capacity building is being undertaken, when the expense of an
assurance opinion is prohibitive (see Annex D for more information).
0.5  The overall aim of validation/verification is to give confidence to intended users that the declared
sustainability information is fairly stated, can be used for the defined purpose and fulfils specified
requirements and criteria. This confidence is provided through an impartial validation/verification process
undertaken by a competent validator/verifier.
0.6  Parties that have an interest in validation/verification include, but are not limited to:
a) clients of validation/verification bodies;
b) validation/verification programme owners and other developers of standards;
c) regulatory authorities;
vi
d) intended users of validated/verified declared sustainability i

Avant-propos
L’ISO (Organisation internationale de normalisation) est une fédération mondiale d’organismes nationaux
de normalisation (comités membres de l’ISO). L’élaboration des Normes internationales est en général
confiée aux comités techniques de l’ISO. Chaque comité membre intéressé par une étude a le droit de faire
partie du comité technique créé à cet effet. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec l’ISO participent également aux travaux. L’ISO collabore étroitement avec
la Commission électrotechnique internationale (IEC) en ce qui concerne la normalisation électrotechnique.
Les procédures utilisées pour élaborer le présent document et celles destinées à sa mise à jour sont
décrites dans les Directives ISO/IEC, Partie 1. Il convient, en particulier, de prendre note des différents
critères d’approbation requis pour les différents types de documents ISO. Le présent document
a été rédigé conformément aux règles de rédaction données dans les Directives ISO/IEC, Partie 2
(voir www.iso.org/directives).

pas reçu notification qu’un ou plusieurs brevets pouvaient être nécessaires à sa mise en application.
Toutefois, il y a lieu d’avertir les responsables de la mise en application du présent document que des
informations plus récentes sont susceptibles de figurer dans la base de données de brevets, disponible à
