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

ISO/FDIS 14019-2:2025(en)
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.
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 ISO 14019-1:—, 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;
d) intended users of validated/verified declared sustainability information (e.g. investors, supply chain
partners, industry bodies, non-governmental organizations (NGOs), consumers) and other interested
parties;
e) accreditation bodies.
vi
ISO/FDIS 14019-2:2025(en)
0.7  Frameworks, principles and processes guiding validation/verification methodologies should be
compatible with the globally accepted quality infrastructure (standardization, conformity assessment by
validation/verification, peer assessment, accreditation). Furthermore, developing these methodologies as
International Standards allows all interested parties, especially those with already implemented structures
and existing instruments, to participate.
0.8  Standards for the declaration and reporting of sustainability information already existing or under
development relate, for instance, to organizations (e.g. listed companies or suppliers) that are increasingly
required to report specific ESG or sustainability matters under voluntary or mandatory arrangements (e.g.
as a pre-requisite to supply chain or market access, precondition for tenders and government procurement,
as part of securities exchange or regulatory annual reporting).
0.9  Within the existing legal framework of many countries and regions, the global system of conformity
assessment and its recognition (e.g. through multilateral arrangements between accreditation bodies), tools
for reliable assessment and confirmation of declared information (claims, reports, etc.) currently exist.
0.10  Parties interested in qualitatively trustworthy and quantitatively comparable information will benefit
from standardized validation/verification processes performed by legal entities that fulfil the requirements
of ISO/IEC 17029.
0.11  While both validation and verification result in a confirmation of declared information, they differ
significantly in their execution. Assessing historic data with respect to truthful and correct statements in
a verification requires different methodological approaches than determining whether declarations on an
intended purpose or future effect are reasonable and plausible in a validation. Therefore, this series includes
1)
separate documents for the validation process (see ISO 14019-3 ) and the verification process (in this
document).
0.12  As for the type of information to be validated or verified, a distinction can be made according to the
sustainability matter (e.g. environmental, social, governance). However, taking the perspective of describing
methodologies, the distinction according to the nature of the assessed information, being quantitative or
qualitative, appears more rational. Hence, this latter approach has been taken in this document.
0.13  The ISO 14019 series provides a consistent overview of the entire validation/verification of
sustainability information, and gives general and specific requirements for validation/verification processes.
0.14  In summary, the ISO 14019 series comprises the following parts:
— ISO 14019-1 contains terminology, principles and general requirements applicable to both validation and
verification;
— ISO 14019-2 (this document) contains specific principles and requirements for verification processes;
1)
— ISO 14019-3 contains specific principles and requirements for validation processes;
— ISO 14019-4 contains specific principles and requirements for validation/verification bodies and their
personnel, the validators and verifiers, in addition to the generic requirements of ISO/IEC 17029.
0.15  Verification processes are generally planned and performed to reach a decision on providing
assurance on whether or not the declared sustainability information fulfils the specified requirements and
criteria. This conclusion is issued as an assurance opinion. When the process is organized to only gather
evidence regarding the fulfilment of specified requirements and criteria, the report on these evidence-
gathering results can be issued as a non-assurance deliverable. Resulting from a review of the evidence, a
non-assurance deliverable can include findings on the suitability, adequacy and effectiveness of the evidence
gathering considered with regard to the fulfilment of specified requirements and criteria. Different terms
can be used to make reference to such non-assurance deliverables (e.g. “findings report” for reviewed
evidence or “evidence report” for results of evidence-gathering without being reviewed).
0.16  For the verification of quantitative information, this document details an 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 into ratio and interval data. Verification approaches include
1) Planned.
vii
ISO/FDIS 14019-2:2025(en)
an assessment of data collection, data editing, data transformation and data control processes, as well as
numerical techniques that aid in the verification of analytical testing.
0.17  For verification of qualitative information, which can be based on numerical and non-numerical
information, this document details an approach to both types, including a review of language, terms and
adjectives used in the declared sustainability information to ensure it is appropriate, consistent with
the available information and truthful. Verification approaches include an assessment of the selection,
determination, collection, editing and control processes associated with the qualitative information. It can
also include the use of professional judgement to review the overall qualitative information to ensure it is
fair and truthful and can be relied on by interested parties.

4 Pre-engagement
4.1 General
In pre-engagement, the verification body shall confirm the following:
a) fulfilment of preconditions, including:
1) specified requirements and criteria for declared sustainability information (see 4.2);
2) suitability of specified requirements and criteria (see 4.3);

ISO/FDIS 14019-2:2025(en)
3) a relevance determination process and rational purpose (see 4.4);
4) common understanding (4.5);
5) actions that will be undertaken if preconditions are found not to have been fulfilled after the
execution has started (see 4.6);
b) the objective is verification (see 4.7), or a mixture of both validation and verification;
NOTE Declared sustainability information can have elements that need verification as well as validation.
c) the type of deliverable (i.e. report of factual findings or assurance opinion) (see 4.8);
d) the scope of verification, specified requirements and criteria to be used to prepare the information to
be verified (e.g. specified requirements for declaring information, including categories of sustainability
matter) (see 4.9);
e) materiality (see 4.10);
f) the level of assurance (see 4.11);
g) any inherent limitations of the deliverable (see 4.12).
4.2 Required information
4.2.1 The verification body shall ensure that the verification programme that has been agreed with the
client includes:
a) applicable specified requirements and criteria for the declared sustainability information;
b) the process and methodology to confirm the relevance determination process of the responsible party’s
declared sustainability information (see 4.4);
c) a process and methodology for verification consistent with the requirements of this document.
4.2.2 The verification body shall ensure that the client obtains sufficient information from the responsible
party to fulfil the requirements of:
a) ISO/IEC 17029:2019, 9.2.1;
b) the applicable parts of the ISO 14019 series.
4.2.3 The verification body shall consider whether the responsible party for the declared sustainability
information has adequately identified and taken into account the specified requirements and criteria,
reporting boundaries, the relevance determination process and value chain considerations that have been
specified in one of the following:
a) the agreed verification programme;
b) any external reporting framework for the declared sustainability information;
c) a framework established by the responsible party or the verification body.
NOTE Reporting boundaries can be, for example, temporal, geographic, physical, economic, demographic or social
(from ISO 14019-1:—, 7.2 f)).
4.2.4 The verification body shall ensure that the client has obtained confirmation from the responsible
party that the responsible party has a basis for issuing the declared sustainability information.

ISO/FDIS 14019-2:2025(en)
4.3 Suitability of specified requirements and criteria
4.3.1 The verification body shall assess whether the specified requirements and criteria proposed by
the responsible party are suitable for the verification to be agreed on with the engagement. This includes
assessing whether the declared sustainability information and sustainability matters:
a) have been subjected to a relevance determination process;
b) are capable of consistent measurement (quantitative information) or evaluation (qualitative
information) against applicable specified requirements and criteria;
c) can be subjected to verification activities for obtaining sufficient appropriate evidence.
NOTE Specified requirements and criteria in established programmes (such as regulatory or voluntary reporting
programmes, applicable International Standards or other assurance standards) are considered to satisfy this
subclause.
4.3.2 In assessing the suitability of specified requirements and criteria, the verification body shall:
a) evaluate whether there are specified requirements and criteria applicable to the declared sustainability
information that will be verified;
b) identify and confirm the sources of the specified requirements and criteria;
c) evaluate whether the specified requirements and criteria exhibit the following characteristics:
1) relevance;
2) completeness;
3) reliability;
4) neutrality;
5) understandability.
4.3.3 Specified requirements and criteria shall be available to intended users identified by the responsible
party and, if applicable, interested parties identified by the responsible party or the verification programme.
4.3.4 If the expected outcome of the verification is an assurance opinion, the verification body shall assess
whether it expects to be able to obtain the evidence needed to support its conclusions.
4.4 Relevance determination process and rational purpose
4.4.1 Unless otherwise specified in the verification programme, the verification body shall:
a) review the relevance determination process that the responsible party has undertaken to identify:
1) relevant sustainability matters, including scope and boundary conditions and any consultations
with interested parties;
2) intended users and the types of decision that they will make for specific purposes based on the
declared sustainability information;
3) criteria which are used for determining relevance;
4) the metrics, units of measurement and changes in sustainability performance that are included in
the declared sustainability information;
5) the qualitative information;

ISO/FDIS 14019-2:2025(en)
6) the likely effects of the declared sustainability information on sustainability outcomes and any
affected parties;
b) question the responsible party on the declared sustainability information to determine whether it
covers the relevant sustainability matters and includes meaningful metrics, units of measurement and
changes in sustainability performance;
c) select the declared sustainability information that will be used in the verification;
d) identify any limitations or omissions with regard to relevant sustainability matters, and explicitly state
those inherent limitations or omissions in any assurance opinion.
NOTE 1 The intent of this subclause is to establish a “relevance determination process test” early on in the
verification process and allow for the verification body to question the responsible party’s declared sustainability
information so that it includes relevant sustainability matters and meaningful metrics, units of measurement and
performance information. By doing this, it is expected that verification activities will avoid focusing on peripheral
or unimportant sustainability matters, metrics, etc. and avoid verifying declared sustainability information that
has little or no actual value in terms of sustainability outcomes (e.g. to avoid greenwashing or misleading claims or
declarations).
NOTE 2 The test of “relevance determination process” in this subclause is not to be confused with the separate
consideration of materiality (see 4.10). The separate assessment of materiality is in relation to the declared
sustainability information found to be relevant after the “relevancy test” has been completed.
4.4.2 The verification body shall decide whether the proposed verification exhibits a rational purpose. In
making this decision, the verification body shall confirm that:
a) it is able to obtain a meaningful level of assurance in the case of an engagement agreement for verification
with a limited assurance;
b) the results of the verification will be useful and not misleading to intended users;
c) the scope of the verification is appropriate;
d) when the scope of the verification excludes part of the declared sustainability information, how this
exclusion is to be communicated to intended users and included in any assurance opinion.
4.5 Lack of mutual understanding
If the requirements of 4.1 to 4.4 are not met, the verification body shall not accept the engagement agreement
on providing assurance.
4.6 Conditions not met after acceptance of the engagement
4.6.1 If it is discovered after the engagement agreement has been accepted that one or more conditions
for verification activities to provide assurance are not met, the verifier shall discuss the matter with the
appropriate parties and determine whether the matter can be resolved to the verification body’s satisfaction.
4.6.2 If the matter cannot be resolved to the verification body’s satisfaction, the verification body shall either:
a) withdraw from the engagement agreement; or
b) if withdrawal is not possible, continue with the verification and express a qualified or adverse opinion,
or a disclaimed opinion, as appropriate in the circumstances.
4.7 Verification objectives
4.7.1 The verifier and client shall agree on the verification objectives taking into account:
a) the verification programme;

ISO/FDIS 14019-2:2025(en)
b) intended users;
c) relevant interested parties;
d) the type of deliverable.
4.7.2 Where the verification will result in an assurance opinion, the verification objectives shall include
reaching a decision about the fair presentation of the declared sustainability information and its conformity
to the specified requirements and criteria.
4.8 Category of deliverable
The verification body and the client shall agree on the type of deliverable (see ISO 14019-1) that is intended
to result from the verification.
NOTE 1 Categories of deliverables are:
a) assurance opinion;
b) non-assurance results, such as reports of factual findings.
NOTE 2 A single engagement agreement can include more than one type of deliverable.
4.9 Specification of scope, requirements and criteria
4.9.1 The verification body and the client shall agree on relevant information to be included in the declared
sustainability information.
4.9.2 The verification body shall apply verification programmes (see ISO 14019-1) that address at least the
following:
a) a description of the declared sustainability information to be verified (e.g. reporting and disclosure,
sustainability matter and its context, qualitative or quantitative information, and, if applicable,
responsible party’s relevance determination process and its outcome);
b) the applicable sustainability matter criteria including the criteria used in the responsible party’s
relevance determination process for selecting the declared sustainability information;
c) exclusions of declared sustainability information from the scope proposed by the client or the
responsible party and accepted by the verification body, including the responsible party’s reasons for
each exclusion;
NOTE Programmes can allow exclusion of declared sustainable information from the agreed scope under
specific conditions, such as:
— legal constraints prevent the disclosure as declared sustainability information;
— rare instances where sustainability information to be declared is confidential, or disclosure of declared
sustainability information would cause more harm than benefit, such as compromising an investigation.
d) requirements and methodology for verification.
4.10 Materiality
The verification body and client shall agree on materiality for the declared sustainability information (both
quantitative and qualitative information).
NOTE 1 Materiality relates to possibility of misstatements, errors, etc. in the sustainability matters (quantitative
and/or qualitative) that is presented in the declared sustainability information. Such declared sustainability
information can include performance metrics, comparisons, graphs, relevance determination process, value chain
information, product or service information.

ISO/FDIS 14019-2:2025(en)
NOTE 2 Professional judgement about materiality is based on the verifier’s perception of the common information
needs of intended users and their purpose, as an individual or group (as applicable), and relate to the surrounding
circumstances.
NOTE 3 Professional judgement related to materiality is not influenced by the agreed level of assurance. As an
example, for the same intended users and their purpose, materiality for a verification with reasonable assurance is the
same as for a verification with limited assurance because materiality is based on the information needs of intended users.
NOTE 4 Materiality relates to the sustainability matter covered by the declared sustainability information.
NOTE 5 A verification can include an evaluation of the responsible party’s determinatio

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) 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 of ISO 14019-1:—, Annex D, for more information).
0.5 0  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
ISO/FDIS 14019-2:2025(en)
d) intended users of validated/verified declared sustainability information (e.g. investors, supply chain
partners, industry bodies, non-governmental organizations (NGOs), consumers) and other interested
parties;
e) accreditation bodies.
0.7  Frameworks, principles and processes guiding validation/verification methodologies should be
compatible with the globally accepted quality infrastructure (standardization, conformity assessment by
validation/verification, peer assessment, accreditation). Furthermore, developing these methodologies as
International Standards allows all interested parties, especially those with already implemented structures
and existing instruments, to participate.
0.8  Standards for the declaration and reporting of sustainability information already existing or under
development relate, for instance, to organizations (e.g. listed companies or suppliers) that are increasingly
required to report specific ESG or sustainability matters under voluntary or mandatory arrangements (e.g. as
a pre-requisite to supply chain or market access, precondition for tenders and government procurement, as
part of securities exchange or regulatory annual reporting).
0.9  Within the existing legal framework of many countries and regions, the global system of conformity
assessment and its recognition (e.g. through multilateral arrangements between accreditation bodies), tools
for reliable assessment and confirmation of declared information (claims, reports, etc.) currently exist.
0.10  Parties interested in qualitatively trustworthy and quantitatively comparable information will benefit
from standardized validation/verification processes performed by legal entities that fulfil the requirements
of ISO/IEC 17029.
0.11  While both validation and verification both result in a confirmation of declared information, they differ
significantly in their execution. Assessing historic data with respect to truthful and correct statements in a
verification requires different methodological approaches than determining whether declarations on an
intended purpose or future effect are reasonable and plausible in a validation. Therefore, this series includes
1)
separate documents for the validation process (see ISO 14019-3) ) and the verification process (in this
document).
0.12  As for the type of information to be validated or verified, a distinction can be made according to the
subjectsustainability matter (e.g. environmental, social, governance). However, taking the perspective of
describing methodologies, the distinction according to the nature of the assessed information, being
quantitative or qualitative, appears more rational. Hence, this latter approach has been taken in this document.
0.13  The ISO 14019 series provides a consistent overview of the entire validation/verification of
sustainability information, and gives general and specific requirements for validation/verification processes.
0.14  In summary, the ISO 14019 series comprises the following parts:
— ISO 14019-1 contains terminology, principles and general requirements applicable to both validation and
verification;
— ISO 14019-2 (this document) contains specific principles and requirements for verification processes;
1 1)
— ISO 14019-3 3 contains specific principles and requirements for verificationvalidation processes;
— ISO 14019-4 contains specific principles and requirements for validation/verification bodies and their
personnel, the validators and verifiers, in addition to the generic requirements of ISO/IEC 17029.

vii
ISO/FDIS 14019-2:2025(en)
0.15  Verification processes are generally planned and performed to reach a decision on providing assurance
on whether or not the declared sustainability information fulfils the specified requirements and criteria. This
conclusion is issued as an assurance opinion. When the process is organized to only gather evidence regarding
the fulfilment of specified requirements and criteria, the report on these evidence-gathering results can be
issued as a non-assurance deliverable. Resulting from a review of the evidence, a non-assurance deliverable
can include findings on the suitability, adequacy and effectiveness of the evidence gathering considered with
regard to the fulfilment of specified requirements and criteria. Different terms can be used to make reference
to such non-assurance deliverables, (e.g. „“findings report“” for reviewed evidence or „“evidence report“” for
results of evidence-gathering without being reviewed.).
0.16  For the verification of quantitative information, this document details an 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 into ratio and interval data. Verification approaches include an assessment of
data collection, data editing, data transformation and data control processes, as well as numerical techniques
that aid in the verification of analytical testing.
0.17  For verification of qualitative information, which can be based on numerical and non-numerical
information, this document details an approach to both types, including a review of language, terms and
adjectives used in the declared sustainability information to ensure it is appropriate, consistent with the
available information and truthful. Verification approaches include an assessment of the selection,
determination, collection, editing and control processes associated with the qualitative information. It can also
include the use of professional judgement to review the overall qualitative information to ensure it is fair and
truthful and can be relied on by interested parties.

4 Pre-engagement
4.1 General
In pre-engagement, the verification body shall confirm the following:
a) fulfilment of preconditions, including:
1) specified requirements and criteria for declared sustainability information (see 4.2);
2) suitability of specified requirements and criteria (see 4.3);
3) a relevance determination process and rational purpose (see 4.4);

ISO/FDIS 14019-2:2025(en)
4) common understanding (4.5);
5) actions that will be undertaken if preconditions are found not to have been fulfilled after the execution
has started (see 4.6);
b) the objective is verification (see 4.7), or a mixture of both validation and verification;
NOTE Declared sustainability information can have elements that need verification as well as validation.
c) the type of deliverable (i.e. report of factual findings or assurance opinion) (see 4.8);
d) the scope of verification, specified requirements and criteria to be used to prepare the information to be
verified (e.g. specified requirements for declaring information, including categories of sustainability
matter) (see 4.9);
e) materiality (see 4.10);
f) the level of assurance (see 4.11);
g) any inherent limitations of the deliverable (see 4.12).
4.2 Required information
4.2.1 The verification body shall ensure that the verification programme that has been agreed with the client
includes:
a) applicable specified requirements and criteria for the declared sustainability information;
b) the process and methodology to confirm the relevance determination process of the responsible party’s
declared sustainability information (see 4.4);
c) a process and methodology for verification consistent with the requirements of this document.
4.2.2 The verification body shall ensure that the client obtains sufficient information from the responsible
party to fulfil the requirements of:
a) ISO/IEC 17029:2019, 9.2.1;
b) the applicable parts of the ISO 14019 series.
4.2.3 The verification body shall consider whether the responsible party for the declared sustainability
information has adequately identified and taken into account the specified requirements and criteria,
reporting boundaries, the relevance determination process and value chain considerations that have been
specified in one of the following:
a) the agreed verification programme; or
b) any external reporting framework for the declared sustainability information; or
c) a framework established by the responsible party or the verification body.
NOTE Reporting boundaries can be, for example, temporal, geographic, physical, economic, demographic, or social
(from ISO 14019-1,:—, 7.2 .f))).
4.2.4 The verification body shall ensure that the client has obtained confirmation from the responsible party
that the responsible party has a basis for issuing the declared sustainability information.
ISO/FDIS 14019-2:2025(en)
4.3 Suitability of specified requirements and criteria
4.3.1 The verification body shall assess whether the specified requirements and criteria proposed by the
responsible party are suitable for the verification to be agreed on with the engagement. This includes, to assess
assessing whether the declared sustainability information and sustainability matters:
a) have been subjected to a relevance determination process;
b) are capable of consistent measurement (quantitative information) or evaluation (qualitative information)
against applicable specified requirements and criteria;
c) can be subjected to verification activities for obtaining sufficient appropriate evidence.
NOTE Specified requirements and criteria in established programmes (such as regulatory or voluntary reporting
programmes, applicable International Standards or other assurance standards) are considered to satisfy this subclause.
4.3.2 In assessing the suitability of specified requirements and criteria, the verification body shall:
a) evaluate whether there are specified requirements and criteria applicable to the declared sustainability
information that will be verified;
b) identify and confirm the sources of the specified requirements and criteria;
c) evaluate whether the specified requirements and criteria exhibit the following characteristics:
1) i) relevance;
2) ii) completeness;
3) iii) reliability;
4) iv) neutrality;
5) v) understandability.
4.3.3 Specified requirements and criteria shall be available to intended users identified by the responsible
party and, if applicable, interested parties identified by the responsible party or the verification programme.
4.3.4 If the expected outcome of the verification is an assurance opinion, the verification body shall assess
whether it expects to be able to obtain the evidence needed to support its conclusions.
4.4 Relevance determination process and rational purpose
4.4.1 Unless otherwise specified in the verification programme, the verification body shall:
a) review the relevance determination process that the responsible party has undertaken to identify:
1) i) relevant sustainability matters, including scope and boundary conditions and any
consultations with interested parties;
2) ii) intended users and the types of decision that they will make for specific purposes based on the
declared sustainability information;
3) iii) criteria which are used for determining relevance;
4) iv) the metrics, units of measurement and changes in sustainability performance that are included
in the declared sustainability information;
ISO/FDIS 14019-2:2025(en)
5) v) the qualitative information;
6) vi) the likely effects of the declared sustainability information on sustainability outcomes and any
affected parties;
b) question the responsible party on the declared sustainability information to determine whether it covers
the relevant sustainability matters and includes meaningful metrics, units of measurement and changes
in sustainability performance;
c) select the declared sustainability information that will be used in the verification;
d) identify any limitations or omissions with regard to relevant sustainability matters, and explicitly state
those inherent limitations or omissions in any assurance opinion.
NOTE 1 The intent of this subclause is to establish a “relevance determination process test” early on in the verification
process and allow for the verification body to question the responsible party’s declared sustainability information so that
it includes relevant sustainability matters and meaningful metrics, units of measurement and performance information.
By doing this, it is expected that verification activities will avoid focusing on peripheral or unimportant sustainability
matters, metrics, etc. and avoid verifying declared sustainability information that has little or no actual value in terms of
sustainability outcomes (e.g. to avoid greenwashing or misleading claims or declarations).
NOTE 2 The test of “relevance determination process” in this subclause is not to be confused with the separate
consideration of materiality (see 4.10). The separate assessment of materiality is in relation to the declared sustainability
information found to be relevant after the “relevancy test” has been completed.
4.4.2 The verification body shall decide whether the proposed verification exhibits a rational purpose. In
making this decision, the verification body shall confirm that:
a) it is able to obtain a meaningful level of assurance in the case of an engagement agreement for verification
with a limited assurance;
b) the results of the verification will be useful and not misleading to intended users;
c) the scope of the verification is appropriate;
d) when the scope of the verification excludes part of the declared sustainability information, how this
exclusion is to be communicated to intended users and included in any assurance opinion.
4.5 Lack of mutual understanding
If the requirements of 4.1 to 4.4 are not met, the verification body shall not accept the engagement agreement
on providing assurance.
4.6 Conditions not met after acceptance of the engagement
4.6.1 If it is discovered after the engagement agreement has been accepted that one or more conditions for
verification activities to provide assurance are not met, the verifier shall discuss the matter with the
appropriate parties and determine whether the matter can be resolved to the verification body’s satisfaction.
4.6.2 If the matter cannot be resolved to the verification body’s satisfaction, the verification body shall
either:
a) withdraw from the engagement agreement; or
b) if withdrawal is not possible, continue with the verification and express a qualified or adverse opinion, or
a disclaimed opinion, as appropriate in the circumstances.
ISO/FDIS 14019-2:2025(en)
4.7 Verification objectives
4.7.1 The verifier and client shall agree on the verification objectives taking into account:
a) the verification programme;
b) intended users;
c) relevant interested parties;
d) the type of deliverable.
4.7.2 Where the verification will result in an assurance opinion, the verification objectives shall include
reaching a decision about the fair presentation of the declared sustainability information and its conformity
to the specified requirements and criteria.
4.8 Category of deliverable
The verification body and the client shall agree on the type of deliverable (see ISO 14019-1) that is intended
to result from the verification.
NOTE 1 Categories of deliverables are:
a) assurance opinion;
b) non-assurance results, such as reports of factual findings.
NOTE 2 A single engagement agreement can include more than one type of deliverable.
4.9 Specification of scope, requirements and criteria
4.9.1 The verification body and the client shall agree on relevant information to be included in the declared
sustainability information.
4.9.2 The verification body shall apply verification programmes (see ISO 14019-1) that address at least the
following:
a) a description of the declared sustainability information to be verified (e.g. reporting and disclosure,
sustainability matter and its context, qualitative or quantitative information, and, if applicable,
responsible party’s relevance determination process and its outcome);
b) the applicable sustainability matter criteria including the criteria used in the responsible party’s relevance
determination process for selecting the declared sustainability information;
c) exclusions of declared sustainability information from the scope proposed by the client or the responsible
party and accepted by the verification body, including the responsible party’s reasons for each exclusion;
NOTE Programmes can allow exclusion of declared sustainable information from the agreed scope under
specific conditions, such as:
— legal constraints prevent the disclosure as declared sustainability information;
— rare instances where sustainability information to be declared is confidential, or disclosure of declared
sustainability information would cause more harm than benefit, such as compromising an investigation.
d) requirements and methodology for verification.
ISO/FDIS 14019-2:2025(en)
4.10 Materiality
The verification body and client shall agree on materiality for the declared sustainability information (both
quantitative and qualitative information).
NOTE 1 Materiality relates to possibility of misstatements, errors, etc. in the sustainability matters (quantitative
and/or qualitative) that is presented in the declared sustainability information. Such declared sustainability information
can include performance metrics, comparisons, graphs, relevance determination process, value chain information,
product or service information.
NOTE 2 Professional judgement about materiality is based on the verifier’s perception of the common information
needs of intended users and their purpose, as an individual or group (as applicable), and relate to the surrounding
circumstances.
NOTE 3 Professional judgement related to materiality is not influenced by the agreed level of assurance. As an
example, for the same intended users and their purpose, materiality for a verification with reasonable assurance is the
same as for a verification with limited assurance because materiality is based on the information needs of intended users.
NOTE 4 Materiality relates to the sustainability matter covered by the declared sustainability information.
NOTE 5 A verification can include an evaluation of the responsible party’s determination of the relevance of its
sustainability information and hence what the responsible party will declare.
NOTE 6 See 6.4 for requirements on the process of assessing materiality.
4.11 Level of assurance
4.11.1 The verification body and the client shall agree on the level of assurance to be applied, if applicable
and not specified by the verification programme. On determining the level of assurance, the verification body
shall check whether the responsible party has taken into consideration the needs of the intended users and
their purpose.
NOTE The level of assurance is specified prior to the start of the verification because the level of assurance
establishes the nature, extent and timing (i.e. the design) of the evidence-gathering activities.
4.11.2 The verifier shall not change the level of assurance during the verification, but can terminate the
verification and agree on a new engagement agreement with a different level of assurance.
NOTE Annex B provides further information on level of assurance.
4.12 Inherent limitations and scope limitations
4.12.1 General
4.12.1.1 Where inherent limitations are known to exist prior to accepting an engagement agreement (see
Clause 5), the verification body shall determine whether the declared sustainability information is assessable
and evidence can be gathered. In particular, the verification body shall assess whether the evidence can be
assessed for the declared sustainability information.
4.12.1.2 If a further limitation is imposed by the client or responsible party after an engagement agreement
to provide assurance has been accepted, the verification body shall consider whether to withdraw from the
engagement agreement, where withdrawal is possible.
4.12.1.3 The verifier shall communicate in the assurance opinion any limitations found during the planning
or execution stages.
ISO/FDIS 14019-2:2025(en)
4.12.2 Evaluating consequences of inherent limitation
4.12.2.1 The verifier shall evaluate the proposed scope, specified requirements and criteria, level of
assurance, and access to relevant material on the quantitative and qualitative information in the declared
sustainability information, to identify any limitations imposed by the responsible party on the verification
activities (see 10.5).
4.12.2.2 Where limitations are found, the verifier shall consider whether they can result in the verifier being
unable to make a decision on assurance of the declared sustainability information. If so, the verifier shall not
accept the engagement agreement as an engagement agreement to provide assurance (see 10.5).
4.12.2.3 The verifier shall document their evaluation of any potential limitations and the outcome of the
evaluation.
NOTE The evaluation of limitations normally occurs as part of risk assessment (see 6.3) and assessment of
materiality (see 6.4).
5 Engagement
The verification body shall have an engagement agreement with each client for the provision of verification
activities that includes:
a) identification of:
1) i) the declared sustainability information;
2) ii) the applicable specified requirements and criteria, including the relevance determination
process for selecting the declared sustainability information;
3) iii) rules and procedures for the methodology of verification;
b) the scope of verification;
c) reference to the requirements for the verification body providing the verification (for example, but not
limited to, competence, impartiality and consistent operation);
d) a statement from the responsible party that confirms that it is responsible for its declared sustainability
information and for conformity with the agreed specified requirements and criteria;
e) provisions for managing any changes to the agreement or ending the agreement;
f) use of the assurance opinion by the responsible party and client;
g) how to reference the assurance opinion or verification process in cases where disclosed sustainability
information is different from declared sustainability information; specifically, if disclosed sustainability
information includes sustainability matters that are not included in declared sustainability information.
6 Planning
6.1 Verification team selection
The verification body shall select a team that has the necessary competence (knowledge, skills, behaviours,
experience, training, etc.) to undertake the verification.
NOTE See ISO 14019-1:—, 4.3.5, and ISO 14019-4:—, 7.3 and Annex A.
ISO/FDIS 14019-2:2025(en)
6.2 Strategic analysis
6.2.1 General
The verifier shall perform and document a strategic analysis to inform the risk assessment (see 6.36.3) the),
evidence-gathering activities (see 6.56.5), the), evidence-gathering plan (see 6.5.8) and verification plan (see
6.5.9).
6.2.2 Context for the strategic analysis
The context of the strategic analysis shall be the following:
a) the declared sustainability information, and its associated sustainability matters, background and
perspective, including issues such as its language and form;
b) the agreement (see Clause 5) related to:
1) i) the declared sustainability information;
2) ii) the specified requirements and criteria for verification, including the relevance determination
process;
c) information about issues of concern to intended users;
d) the verifier’s own research related to the responsible party’s public commitments and communication
related to sustainability (this includes information outside the scope of the declared sustainability
information);
e) whether an intended user has been identified to act in the interests of interested parties.
6.2.3 Strategic analysis approach
6.2.3.1 The verifier shall include the following matters when undertaking strategic analysis:
a) the agreed sustainability matter, its background and perspective;
b) matters agreed in the engagement agreement such as relevance determination process, intended users
and their purpose, level of assurance, materiality, type of deliverables and the outcome of previous
verifications;
c) an evaluation of the responsible party’s public commitments and communication related to sustainability
(this includes information outside the scope of the declared sustainability information, including the
nature of the parties in the value chain, systems thinking and life cycle approach);
d) the responsible party’s business model and operations as they relate to the declared sustainability
information;
e) a statement from the responsible party that the declared sustainability information is correct and true;
f) matters related to the declared sustainability information, including:
1) i) the likely accuracy and completeness of the sustainability information, including data integrity
and uncertainty;
NOTE For uncertainty, see Annex D.
ISO/FDIS 14019-2:2025(en)

Introduction
0.1  Compte tenu de la demande croissante du public et de l’avancée des dispositions légales (réglementaires
et contractuelles) en ce qui concerne les déclarations, divulgations et communications d’informations en
matière de durabilité, un besoin significatif du marché a été identifié pour la validation, la vérification et
l’assurance de ces informations.
0.2  Des normes sont nécessaires à la fois pour:
a) l’identification du système métrique et des indicateurs, la surveillance, la compilation, la communication,
la déclaration et la divulgation d’informations sur les questions de durabilité (à savoir les questions
environnementales, sociales et de gouvernance [ESG]);
b) des approches harmonisées pour la validation/vérification et l’assurance de ces informations.
Des informations en matière de durabilité validées et vérifiées peuvent être utilisées pour la prise de
décision, y compris des décisions d’investissement, des décisions d’approvisionnement ou pour les choix
individuels lors d’achats de biens de consommation, l’utilisation de services et le choix du lieu de travail.
0.3  Dans le présent document, seules les informations en matière de durabilité qui sont déclarées par
une partie responsable font l’objet de la validation/vérification. Les organismes de validation/vérification
évaluent si les informations déclarées en matière de durabilité satisfont et respectent les exigences et
critères spécifiés.
0.4  Les exigences et critères spécifiés sont définis par un programme de validation/vérification qui peut
être un programme de rapports réglementaires obligatoires ou un programme volontaire pour un secteur ou
une question spécifique concernant la durabilité. Le résultat de la réalisation d’une validation/vérification
peut être la délivrance d’un avis d’assurance qui atteste que:
a) les exigences et les critères spécifiés ont été satisfaits;
b) le caractère raisonnable des hypothèses, limitations et méthodes qui soutiennent les informations
déclarées en matière de durabilité concernant un résultat futur a été validé;
c) l’exactitude d’importance significative et la représentation fidèle des données et informations
historiques ont été vérifiées.
NOTE Le principal résultat des activités de validation/vérification selon la série ISO 14019 est un avis d’assurance.
En outre, la série ISO 14019 permet d’obtenir divers résultats ou livrables de non-assurance. Le livrable choisi pour
chaque activité de validation/vérification spécifique (c’est-à-dire un avis d’assurance ou un livrable de non-assurance)
est spécifié dans le programme de validation/vérification concerné et confirmé entre l’organisme de validation et
de vérification et son client dans un accord d’engagement spécifique. Les livrables de non-assurance comprennent
les rapports de faits constatés basés sur les rapports sur les procédures convenues, les rapports de constatations
et les rapports de preuves. Ces livrables de non-assurance peuvent être appropriés dans les situations où un avis
d’assurance n’est pas requis, par exemple dans le cadre de l’établissement d’un rapport volontaire ou interne, d’un
rapport provenant d’organisations en amont ou en aval de la chaîne de valeur, pour les petites et moyennes entreprises
(PME), dans les situations où un renforcement des capacités est entrepris ou lorsque le coût d’un avis d’assurance est
prohibitif (voir l’ISO 14019-1:—, Annexe D, pour plus d’informations).
0.5  L’objectif général de la validation/vérification est de donner confiance aux utilisateurs cibles quant
au fait que les informations déclarées en matière de durabilité correspondent à la réalité, qu’elles peuvent
être utilisées pour l’objectif défini et qu’elles satisfont aux exigences et critères spécifiés. Cette confiance
est assurée par un processus de validation ou de vérification impartial mis en œuvre par un validateur/
vérificateur compétent.
0.6  Les parties qui trouvent un intérêt à la validation/vérification comprennent, sans toutefois s’y limiter:
a) les clients des organismes de validation/vérification;
b) les propriétaires de programmes de validation/vérification et autres rédacteurs de normes;
c) les autorités de réglementation;

vi
ISO/FDIS 14019-2:2025(fr)
d) les utilisateurs cibles d’informations déclarées en matière de durabilité validées/vérifiées (par exemple,
investisseurs, partenaires de la chaîne d’approvisionnement, organismes industriels, organisations non
gouvernementales (ONG), consommateurs) et autres parties intéressées;
e) les organismes d’accréditation.
0.7  Il convient que les cadres, les principes et les processus guidant les méthodologies de validation/
vérification soient compatibles avec l’infrastructure de la qualité internationalement reconnue
(normalisation, évaluation de la conformité par la validation et la vérification, évaluation par des pairs,
accréditation). En outre, l’élaboration de ces méthodologies en tant que Normes internationales permet
à toutes les parties intéressées, en particulier celles qui ont des structures déjà mises en œuvre et des
instruments existants, de participer.
0.8  Les normes relatives à la déclaration et à la communication d’informations en matière de durabilité
(déjà existantes ou en cours de développement) concernent, par exemple, les organismes (par exemple,
les sociétés cotées ou les fournisseurs) qui sont de plus en plus incités à établir des rapports sur des questions
d’ESG ou de durabilité spécifiques en vertu de dispositions volontaires ou obligatoires (par exemple, comme
un prérequis pour accéder à une chaîne d’approvisionnement ou à un marché, une condition préalable
aux appels d’offres et aux marchés publics, dans le cadre des marchés financiers ou des rapports annuels
réglementaires).
0.9  Dans le cadre juridique actuel de nombreux pays et régions, le système international d’évaluation de
la conformité et sa reconnaissance (par exemple, par le biais d’accords multilatéraux entre les organismes
d’accréditation) ainsi que des outils d’évaluation et de confirmation fiables des informations déclarées
(réclamations, rapports, etc.) existent déjà.
0.10  Les parties intéressées par des informations qualitativement fiables et quantitativement comparables
bénéficieront de processus de validation/vérification normalisés mis en œuvre par des entités juridiques
qui satisfont aux exigences de l’ISO/IEC 17029.
0.11  Bien que la validation et la vérification entraînent toutes deux une confirmation des informations
déclarées, leur exécution diffère considérablement. Dans le cadre d’une vérification, l’évaluation des données
historiques au regard d’énoncés véridiques et corrects nécessite des approches méthodologiques différentes
de celle visant à déterminer si les déclarations sur un objectif prévu ou un effet futur sont raisonnables et
plausibles dans le cadre d’une validation. Par conséquent, cette série inclut des documents distincts pour le
1)
processus de validation (voir l’ISO 14019-3 ) et le processus de vérification (dans le présent document).
0.12  En ce qui concerne le type d’information à valider ou à vérifier, une distinction peut être faite selon
la question de durabilité (par exemple environnementale, sociale, de gouvernance). Toutefois, dans la
perspective de la description des méthodologies, la distinction selon la nature des informations évaluées,
qu’elles soient quantitatives ou qualitatives, semble plus rationnelle. Cette dernière approche a donc été
retenue dans le présent document.
0.13  La série ISO 14019 fournit une présentation cohérente de l’intégralité de la validation/vérification des
informations en matière de durabilité, et donne des exigences générales et spécifiques pour les processus de
validation/vérification.
0.14  En résumé, la série ISO 14019 comprend les parties suivantes:
— l’ISO 14019-1 contient la terminologie, les principes et les exigences générales applicables à la validation
et à la vérification;
— l’ISO 14019-2 (le présent document) contient les principes et les exigences spécifiques pour les processus
de vérification;
1)
— l’ISO 14019-3 contient les principes et les exigences spécifiques pour les processus de validation;
— l’ISO 14019-4 contient les principes et les exigences spécifiques pour les organismes de validation/
vérification et leur personnel, les validateurs et les vérificateurs, en plus des exigences génériques de
l’ISO/IEC 17029.
1) Prévue.
vii
ISO/FDIS 14019-2:2025(fr)
0.15  Les processus de vérification sont généralement planifiés et mis en œuvre afin de parvenir à une
décision sur l’assurance ou non que les informations déclarées en matière de durabilité satisfont aux
exigences et critères spécifiés. Cette conclusion est délivrée sous forme d’avis d’assurance. Lorsque le
processus est organisé pour recueillir des preuves concernant uniquement le respect des exigences et
critères spécifiés, le rapport portant sur les résultats de collecte de ces preuves peut être émis sous la forme
d’un livrable de non-assurance. Résultant d’un examen des preuves, un livrable de non-assurance peut
inclure des constatations sur la pertinence, l’adéquation et l’efficacité de la collecte des preuves considérée
en ce qui concerne le respect des exigences et critères spécifiés. Différents termes peuvent être utilisés
pour faire référence à ces livrables de non-assurance (par exemple, «rapport de constatations» pour des
preuves examinées ou «rapport de preuves» pour les résultats d’une collecte de preuves sans qu’elles soient
examinées).
0.16  Pour la vérification des informations quantitatives, le présent document détaille une approche
pour les formes continues ou discrètes de données et les types de collectes de preuves qui peuvent être
applicables à chacune. Les données continues peuvent également être classées en données de rapport et
d’intervalle. Les approches de vérification comprennent une évaluation de la collecte de données, de l’édition
des données, de la transformation des données et des processus de contrôle des données, ainsi que des
techniques numériques qui facilitent la vérification des examens analytiques.
0.17  Pour la vérification des informations qualitatives, qui peuvent être basées sur des informations
numériques ou non numériques, le présent document détaille une approche pour les deux types, y compris
un examen du langage, des termes et des adjectifs utilisés dans les informations déclarées en matière de
durabilité pour s’assurer qu’elles sont appropriées, cohérentes avec les informations disponibles et véridiques.
Les approches de vérification comprennent une évaluation des processus de sélection, de détermination, de
collecte, de révision et de contrôle associés aux informations qualitatives. La vérification peut également
inclure le recours à un jugement professionnel pour examiner les informations qualitatives dans leur
intégralité afin de s’assurer qu’elles sont justes et véridiques et qu’elles peuvent être utilisées par les parties
intéressées.

b) interroger la partie responsable sur les informations déclarées en matière de durabilité afin de
déterminer si elles couvrent les questions pertinentes de durabilité et comprennent des indicateurs,
des unités de mesure et des changements significatifs dans la performance en matière de durabilité;
c) sélectionner les informations déclarées en matière de durabilité qui seront vérifiées;
d) identifier toutes les limitations ou omissions en ce qui concerne les questions pertinentes concernant la
durabilité, et indiquer explicitement ces limitations ou omissions inhérentes dans tout avis d’assurance.
NOTE 1 L’objectif du présent paragraphe est d’établir un «examen du processus de détermination de la pertinence»
dès le début du processus de vérification et de permettre à l’organisme de vérification de remettre en question les
informations déclarées en matière de durabilité par la partie responsable de manière à ce qu’elles comprennent des
questions pertinentes de durabilité et des indicateurs, unités de mesure et informations de performance significatifs.
Ce faisant, il est attendu que les activités de vérification évitent de se concentrer sur des questions de durabilité
périphériques ou sans importance, des indicateurs, etc., et évitent de vérifier des informations déclarées en matière
de durabilité qui ont peu ou qui n’ont pas de valeur réelle du point de vue des résultats en matière de durabilité
(par exemple, pour éviter l’« écoblanchiment » ou les allégations ou déclarations trompeuses).
NOTE 2 L’examen du «processus de détermination de la pertinence» dans le présent paragraphe ne doit pas être
confondu avec l’appréciation dissociée de l’importance relative (voir 4.10). L’évaluation dissociée de l’importance
relative se rapporte aux informations déclarées en matière de durabilité jugées pertinentes après la réalisation du
«test de pertinence».
4.4.2 L’organisme de vérification doit décider si la vérification proposée présente un objectif cohérent.
En prenant cette décision, l’organisme de vérification doit confirmer que:
a) il est en mesure d’obtenir un niveau d’assurance significatif dans le cas d’un accord d’engagement pour
une vérification avec une assurance limitée;
b) les résultats de la vérification seront utiles et n’induiront pas les utilisateurs cibles en erreur;
c) le périmètre de la vérification est approprié;
d) lorsque le périmètre de la vérification exclut une partie des informations déclarées en matière de
durabilité, confirmer que la manière dont cette exclusion doit être communiquée aux utilisateurs cibles
est satisfaisante et qu’elle sera incluse dans tout avis d’assurance.

4.5 Absence de compréhension mutuelle
Si les exigences de 4.1 à 4.4 ne sont pas satisfaites, l’organisme de vérification ne doit pas accepter l’accord
d’engagement pour la délivrance d’une assurance.
4.6 Conditions non remplies après acceptation de l’engagement
4.6.1 S’il est constaté après l’acceptation de l’accord d’engagement qu’une ou plusieurs conditions des
activités de vérification visant à délivrer une assurance ne sont pas remplies, le vérificateur doit discuter
de la question avec les parties appropriées et déterminer si la question peut être résolue à la satisfaction de
l’organisme de vérification.
4.6.2 Si la question ne peut pas être résolue à la satisfaction de l’organisme de vérification, l’organisme de
vérification doit soit:
a) se retirer de l’accord d’engagement; soit
b) si le retrait n’est pas possible, poursuivre la vérification et exprimer un avis nuancé ou défavorable,
ou une impossibilité de donner un avis, selon le cas.
4.7 Objectifs de la vérification
