119 FOREWORD
120 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
121 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
122 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
123 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
124 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
125 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
126 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
127 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
128 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
129 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
130 consensus of opinion on the relevant subjects since each technical committee has representation from all
131 interested IEC National Committees.
132 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
133 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
134 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
135 misinterpretation by any end user.
136 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
137 transparently to the maximum extent possible in their national and regional publications. Any divergence between
138 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
139 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
140 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
141 services carried out by independent certification bodies.
142 6) All users should ensure that they have the latest edition of this publication.
143 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
144 members of its technical committees and IEC National Committees for any personal injury, property damage or
145 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
146 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
147 Publications.
148 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
149 indispensable for the correct application of this publication.
150 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
151 rights. IEC shall not be held responsible for identifying any or all such patent rights.

169 INTRODUCTION
170 Based on IPCC reports regarding global warming, there is broad understanding that greenhouse
171 gas (GHG) emissions must be significantly reduced in the coming 10 or more years. Products
172 and systems including ones called as solution composed of electric and electronic (EE) products,
173 operated and controlled by new digital technologies and methods such as AI, digital twins and
174 IoT can significantly change patterns of energy usage for energy intensive activities, although
175 having by themselves an environmental impact.
176 Such a change of the pattern of energy usage by adding a digital technology has the potential
177 to avoid GHG emissions represented by CO emission for energy intensive activities. Although
178 the EE products themselves lead to GHG emissions, the GHG emission of the complete activity
179 is significantly lowered, so that the net effect is a reduction of GHG emissions. As a
180 consequence of them expanding to meet future decarbonization needs, many EE businesses
181 will increase their total emissions (in contrast to e.g., a fossil fuel business that is scaling down
182 and showing reduced emissions) and many new products will be manufactured, creating
183 emissions that didn’t exist before. The concept of avoided emissions provides a way of showing
184 that they are still contributing a net improvement to society.
185 The necessity of a sector specific approach applicable to EE products and systems is
186 recognized by considering the specific characteristics of EE products which could include a
187 large quantity of components/materials in a product, dynamic, long, and complicated supply
188 chains, rapidly evolving technology, the complexity of production processes, and use/end-of-
189 life scenarios, etc., which can lead to considerable challenges in performing CFP, emission
190 reductions and avoided emissions.
191 Furthermore, manufacturers of products, systems composed of EE products need robust and
192 reliable calculation methods to establish the amount of avoided emissions caused by their
193 products, systems and solutions. One of important purpose for this standard is to define
194 methodologies which assess avoided emissions from the use of new technologies in an
195 unambiguous and transparent manner.
196 Use of this GHG standard allows the EE industry to declare or disclose the information about
197 GHG emissions, emission reductions and avoided emissions from any EE products, systems
198 on the basis of an international standard, linking social needs for GHG emission reductions.
199 Through the information disclosure based on this IEC standard, EE industry can claim fairly that
200 the products, services and systems can reduce/avoid users’ emissions and contribute to solving
201 societal issues directly linked with UN-SDG13 Climate Action.
202 This document refers to established methodologies stipulated by international standards such
203 as Life Cycle Assessment (LCA) methods covered by existing product specific rules (PSR) when
204 defined or to product category rules (PCR) when defined. See IEC 63336 CDV (Current status)
205 for EE products or ITU 1410 for ICT products and services or to ISO 14040 for any other
206 products and services.
207 The PCRs and PSRs address the climate change impact category within GHG emissions
208 quantification. The methodologies in this document are based on ISO 14064 series and
209 ISO 14067 which might be completed by GHG protocol methodologies if any.

211 GHG EMISSION REDUCTIONS/AVOIDED EMISSIONS FROM ELECTRIC
212 AND ELECTRONIC PRODUCTS AND SYSTEMS – PRINCIPLES,
213 METHODOLOGIES, REQUIREMENTS AND GUIDANCE
215 1 Scope
216 This document describes principles and methodologies, specifies requirements and provides
217 guidance for GHG quantification and communication of Carbon footprint, emission reductions
218 and avoided emissions from electric and electronic (EE) products and systems. The GHG
219 quantification such as carbon footprint of product (CFP) is based on life cycle assessment (LCA)
220 methods.
221 This document is applicable to EE products, systems and EE product-related GHG project.
222 In accordance with IEC Guide 108, this basic essential horizontal standard is intended for use
223 by product committees as a starting point in preparing GHG quantification and communication
224 standards for their own product families. Specific requirements developed by product
225 committees in their standards take precedence over requirements in this standard.
226 When there is no specified standard available in a product committee, this generic essential
227 horizontal standard could be applied by GHG quantification and communication practitioners
228 with recorded complementary specifications.
