ISO 14064-2:2019(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 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.

This document 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.

ISO 14064-3 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 have to 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

A standardized approach for quantification, monitoring and reporting is needed for GHG projects

and any resulting GHG emission reductions and/or removal enhancements, in order that they are

comparable among intended users and GHG programmes. Accordingly, this document specifies a

general, GHG programme-neutral framework and uses terms and concepts designed to be compatible

with other requirements and guidance from relevant GHG policies and programmes, good practice,

legislation and standards. Reference [14] provides an example of good practice guidance.

This document contains general requirements for GHG projects and does not prescribe specific criteria

and procedures. GHG programmes (e.g. GHG offset programmes) may apply additional requirements on

GHG projects in relation to additionality, specific methodologies, project baselines, etc. Although this

document leaves specific criteria and requirements related to additionality to individual programmes,

it does require that the GHG project should result in emission reductions or removal enhancements in

addition to what would have happened in the absence of the project.

This document requires the project proponent to identify and select GHG sources, sinks and reservoirs

(SSRs) relevant for the GHG project and to determine the GHG baseline. GHG project emissions/removals

and baseline scenario emissions/removals are quantified separately, and the emission reductions

© ISO 2019 – All rights reserved vii
---------------------- Page: 13 ----------------------
SIST EN ISO 14064-2:2019
ISO 14064-2:2019(E)

and/or removal enhancements are calculated by comparison of the GHG project emissions/removals

with the baseline scenario emissions/removals. It is important to demonstrate that the GHG baseline

is consistent with the principles of this document, including conservativeness and accuracy, in order

to increase the level of confidence that GHG emission reductions and/or removal enhancements are

credible and not over-estimated. Generally, the GHG baseline could be determined based on historical

information or setting of alternative scenarios according to the requirements of the intended user/

programme. For both the project emissions and the baseline scenario, the quantification, monitoring

and reporting of GHG emissions and removals are based on procedures developed by the project

proponent or adopted from a GHG programme.

This document does not use the term “project boundary”. In order to be compatible with the broadest

range of GHG programmes, project boundary is referred to as SSR that are relevant to the project. If any

GHG programme requires a specific time period or methodology, these can be compared to the GHG

baseline and estimated project emissions. Any discrepancies are recorded and reported in the GHG report.

This document does not specify requirements for verification/validation bodies or verifiers/validators

in providing assurance against GHG statements or claims by GHG projects. Such requirements may

be specified by the authority of the applicable GHG programme or can be found in ISO 14064-3. The

process to recognize certified GHG emission reductions or removal enhancements as GHG units, credits

or offsets is an extension of the GHG project cycle. The certification and crediting process, which may be

under the authority of a GHG programme and may vary among GHG programmes, is also not included in

the specifications of this document.
Annex A provides guidance on the use of this document.
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.
Justification has two more criteria:
c) explain why alternative approaches were not chosen;
d) provide supporting data or analysis.
