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).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

This document was prepared by Technical Committee ISO/TC 207, Environmental management,
Subcommittee SC 7, Greenhouse gas management and related activities.
This second edition cancels and replaces the first edition (ISO 14064-3:2006), which has been
technically revised. The main changes compared with the previous edition are as follows.
— The structure of the document has been changed so that verification and validation are discussed
in sequence (see Clauses 6 and 7) rather than in parallel, because the processes of verification and
validation are significantly different.
— The definitions of verification and validation and other key terms have been changed (see Clause 3).
— A new section on validation has been added (see Clause 7). It applies to future estimates of emissions,
removals, emission reductions and removal enhancements. The purpose of validation is to provide
assurance on the assumptions, limitations and methods used to develop a GHG statement.
— A new Annex A has been added that defines requirements for verifiers to follow when undertaking
engagements at a limited level of assurance.
— A new Annex B has been added on considerations for verification.
— A new Annex C has been added on a new process called agreed-upon procedures (AUP), which allows
for a selection of verification activities to be performed and reported upon. No opinion is expressed
on the result of an AUP engagement as the intended user(s) are responsible for interpreting the
information reported on by the verifier.
— A new Annex D has been added that provides guidance on how verifiers and validators can provide
statements on engagements that are mixed.
— Requirements and guidance on the use of levels of assurance have been added.

ISO 14064-3:2019(E)
Introduction
0.1  Background
Climate change arising from anthropogenic activity has been identified as one of the greatest challenges
facing the world and will continue to affect business and citizens over future decades.
Climate change has implications for both human and natural systems and could lead to significant
impacts on resource availability, economic activity and human wellbeing. In response, international,
regional, national and local initiatives are being developed and implemented by public and private
sectors to mitigate greenhouse gas (GHG) concentrations in the Earth’s atmosphere as well as to
facilitate adaptation to climate change.
There is a need for an effective and progressive response to the urgent threat of climate change
on the basis of the best available scientific knowledge. ISO produces documents that support the
transformation of scientific knowledge into tools that will help address climate change.
GHG initiatives on mitigation rely on the quantification, monitoring, reporting and verification of GHG
emissions and/or removals.
The ISO 14060 family of standards provides clarity and consistency for quantifying, monitoring,
reporting and validating or verifying GHG emissions and removals to support sustainable development
through a low-carbon economy and to benefit organizations, project proponents and interested parties
worldwide. Specifically, the use of the ISO 14060 family of standards:
— enhances the environmental integrity of GHG quantification;
— enhances the credibility, consistency and transparency of GHG quantification, monitoring, reporting,
verification and validation;
— facilitates the development and implementation of GHG management strategies and plans;
— facilitates the development and implementation of mitigation actions through emission reductions
or removal enhancements;
— facilitates the ability to track performance and progress in the reduction of GHG emissions and/or
increase in GHG removals.
Applications of the ISO 14060 family of standards include:
— corporate decisions, such as identifying emission reduction opportunities and increasing
profitability by reducing energy consumption;
— carbon risk management, such as the identification and management of risks and opportunities;
— voluntary initiatives, such as participation in voluntary GHG registries or sustainability reporting
initiatives;
— GHG markets, such as the buying and selling of GHG allowances or credits;
— regulatory/government GHG programmes, such as credit for early action, agreements or national
and local reporting initiatives.
ISO 14064-1 details principles and requirements for designing, developing, managing and reporting
organization-level GHG inventories.
It includes requirements for determining GHG emission and removal boundaries, quantifying an
organization’s GHG emissions and removals, and identifying specific company actions or activities
aimed at improving GHG management.
It also includes requirements and guidance on inventory quality management, reporting, internal
auditing and the organization’s responsibilities in verification activities.
ISO 14064-3:2019(E)
ISO 14064-2 details principles and requirements for determining baselines, and monitoring, quantifying
and reporting of project emissions. It focuses on GHG projects or project-based activities specifically
designed to reduce GHG emissions and/or enhance GHG removals. It provides the basis for GHG projects
to be verified and validated.
This document details requirements for verifying GHG statements related to GHG inventories, GHG
projects, and carbon footprints of products. It describes the process for verification or validation,
including verification or validation planning, assessment procedures, and the evaluation of
organizational, project and product GHG statements.
ISO 14065 defines requirements for bodies that validate and verify GHG statements. Its requirements
cover impartiality, competence, communication, validation and verification processes, appeals,
complaints, and the management system of validation and verification bodies. It can be used as a
basis for accreditation and other forms of recognition in relation to the impartiality, competence, and
consistency of validation and verification bodies.
ISO 14066 specifies competence requirements for validation teams and verification teams. It includes
principles and specifies competence requirements based on the tasks that validation teams or
verification teams must be able to perform.
ISO 14067 defines the principles, requirements and guidelines for the quantification of carbon footprint

of products. The aim of ISO 14067 is to quantify GHG emissions associated with the life cycle stages of
a product, beginning with resource extraction and raw material sourcing and extending through the
production, use and end-of-life stages of the product.
ISO/TR 14069 assists users in the application of ISO 14064-1, providing guidelines and examples for
improving transparency in the quantification of emissions and their reporting. It does not provide
additional guidance to ISO 14064-1.
Figure 1 illustrates the relationship among the ISO 14060 family of GHG standards.

Figure 1 — Relationship among the ISO 14060 family of GHG standards
0.2  Approach of this document
This document details requirements for verifying GHG statements related to GHG inventories, GHG
projects and carbon footprints of products. It describes verification activities that can enable a verifier
to issue an opinion on GHG statements regarding emissions that are attributed to any organization,
project or normalized unit (e.g. product). The data and information that are subject to verification are
historical in nature.
This document also details requirements for validating the assumptions, limitations and methods that
support a statement about the outcome of future activities. Validation differs from verification because
its subject is data and information that are prospective and generally based on past performance. This
document recognizes the different process requirements that apply to the validation of assumptions
and methods.
This document can be used by first-, second- and third-party GHG verifiers and validators. It is regime
neutral, meaning that it can be used for verifying and validating GHG statements regardless of the
criteria used to develop those statements.
ISO 14064-3:2019(E)
This document provides requirements and guidance for those persons performing verification and
validation of GHG data and information. It is intended to be useful to a broad range of potential users,
including:
— first-, second- and third-party GHG verifiers and validators;
— organizations and individuals involved in developing and commissioning GHG projects;
— organizations conducting internal audits of their GHG data and information;
— organizations involved in GHG verifier or validator training;
— voluntary and mandatory GHG programme administrators;
— investor, finance and insurance communities;
— regulators and those involved in the accreditation and conformity assessment of emissions trading
and emission or removal offset programmes.
Figure 2 explains the application of verification, validation and AUP.
Figure 2 — Decision process for engagement type
In this document, validation is described as a specific type of engagement that assesses the assumptions,
limitations and methods that generate hypothetical or projected data and information, i.e. estimates of
the outcomes of future events.
0.3  Significance of the terms “explain” and “justify” in this document
Some clauses require users of this document to explain and justify the use of certain approaches or
decisions taken.
Explanation generally includes:
a) how approaches were used or decisions taken;
b) why approaches were chosen or decisions made.
x © ISO 2019 – All rights reserved

ISO 14064-3:2019(E)
Justification has two more criteria:
c) explain why alternative approaches were not chosen;
d) provide supporting data or analysis.
