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 activity 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 report

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
