Sustainability information — Part 2: Principles and requirements for verification processes
This document specifies requirements for the verification process of quantitative and qualitative sustainability information, including reporting on environmental, social, governance (ESG) and other sustainability aspects. It applies to the set of rules and procedures for carrying out verification by providing elements of a verification programme, such as process, evidence-gathering activities, reporting. This document addresses uncertainty in values and how to address these uncertainties. It addresses primary and secondary sources of data and how they relate to the strength of verification evidence. For the verification of quantitative information, it details the approach for continuous and discrete forms of data and the types of evidence gathering activities that can be applicable to each. Continuous data can be further categorized ratio and interval data. Verification approaches include an assessment of data collection, data editing, data transformation, data control processes as well as numerical techniques that aid in verification analytical testing. For verification of qualitative information, it details the approach for binary, ordinal, and nominal forms of data and the types of evidence gathering activities that can be applicable to each. Verification approaches include an assessment of data collection, data editing, data transformation, data control processes as well as numerical techniques that aid in verification analytical testing

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 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/verification. Validation/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) re
