17、 BASELINE FOR ELECTRICAL AND ELECTRONIC PRODUCTS AND SYSTEMS FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co

18、-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred

19、to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in thi

20、s preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an internationa

21、l consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable ef

22、forts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publica

23、tions transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. In

24、dependent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) N

25、o liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs

26、 (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct applicat

27、ion of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. The main task of IEC technical committees is to prepare Internatio

28、nal Standards. However, a technical committee may propose the publication of a technical report when it has collected data of a different kind from that which is normally published as an International Standard, for example “state of the art“. IEC TR 62726, which is a technical report, has been prepa

29、red by IEC technical committee 111: Environmental standardization for electrical and electronic products and systems. The text of this technical report is based on the following documents: Enquiry draft Report on voting 111/335/DTR 111/345/RVC Full information on the voting for the approval of this

30、technical report can be found in the report on voting indicated in the above table. PD IEC/TR 62726:2014IEC TR 62726:2014 IEC 2014 5 This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. The committee has decided that the contents of this publication will remain unchan

31、ged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual version of this publication may be issued at

33、TR 62726:2014 IEC 2014 INTRODUCTION Electrical and electronic products and systems (hereinafter referred to as EE products) are widely used in our society, hence raising awareness of their environmental impacts. Consequently customers in the market and other stakeholders are requiring, or requesting

34、 that the electronics sector takes action to address the quantification and reduction of environmental impacts through environmental conscious design during the product development phase. Among those environmental impacts, climate change is an important issue. A number of initiatives at local, natio

35、nal, regional, and international levels are being developed and implemented, aiming to curb the concentration of greenhouse gas (GHG) emissions which is understood to be a major causative factor. All industry sectors are trying to reduce GHG emissions in order to meet the national, regional and glob

36、al reduction targets for the future in order to stabilize atmospheric concentration below the level of triggering catastrophic climate change. For the EE sector, developing and supplying new products that achieve GHG reductions in society compared to other products offers significant opportunities f

37、or achieving large scale GHG reductions. Among methodologies to quantify products impacts on climate change is carbon footprint of products (CFP), which only covers GHG emissions that occur during the life cycle of the product. Although EE products consume energy, the EE industry is enabling other s

38、ectors to reduce large amounts of GHG emission. There are different opportunities for GHG reduction when the EE industry provides the same or similar function as existing products in the marketplace but with significantly less GHG emissions. For example, a manufacturer of renewable energy technologi

39、es can be interested not only in tracking the emissions and reductions that occur during the life cycle of its products, but also in assessing the reduction in societys GHG emissions as a result of using renewable energy technologies compared to generating electricity by combusting fossil fuels. Exa

40、mples of such products and solutions include: wind turbines or solar panels, compared to fossil fuel power plants; LED bulbs, compared to incandescent bulbs; online meeting (including software), compared to business travel. For assessing this enabling effect, two scenarios are compared: the situatio

41、n “with the technology” and “without or with old technology”. Because the enabling effect is not included in CFP, quantification of such reductions requires a different methodology. Actually many companies are already quantifying or communicating future environmental contribution by this enabling ef

42、fect through their businesses with numeric target values, such as “help society to reduce XX million tons by 2025 through our high energy-efficient products”. Currently, various quantifications and claims for such GHG reduction are carried out mainly on a voluntary basis. However, there is no intern

43、ationally recognized methodology to validate such numerical targets specifically for EE products. There is a business value in establishing an internationally recognized methodology at this time. A basic generic and relevant methodology is provided by ISO 14064-2 1 . This ISO standard also incorpora

44、tes the idea of “product-related GHG projects” and allows GHG projects to be performed as a result of product development. 1Numbers in square brackets refer to the Bibliography PD IEC/TR 62726:2014IEC TR 62726:2014 IEC 2014 7 The idea is related to EE products contributing to GHG emissions reduction

45、 such as high energy efficient EE equipment. The necessity of a sector-specific guidance applicable to the EE sector is recognized by considering specific characteristics of EE. These include their complex and dynamic supply chain, their varying lifespan, sometimes extending over many years, and ass

46、ociated energy consumption. Such characteristics underline the significance of the use stage of many EE products. In accordance with ISO 14064-2, this report addresses “EE product-related GHG projects” as activity or activities performed as a result of the development and supply of EE products into

47、the market alter the conditions identified in the baseline scenario which cause greenhouse gas emissions reduction, as well as the methodology associated with it. In particular, the objectives of this report are as follows: enable organizations in the EE sector to quantify their contribution to soci

48、ety in reducing GHG emissions through their products and systems; allow EE product-related GHG projects to be evaluated in terms of their GHG emission reductions amount compared to a baseline. In addition to the above purposes, the additional benefits below are also expected: facilitate incorporatio

49、n of a GHG related target into design and development strategy of EE products; establish consistency and bridging between different product areas in the EE sector; help product-specific technical committees (TCs) with limited amount of expertise or resources to develop their own methodology. The features of this report are as follows: This report contains the study and review of relevant standards, regional initiatives and practices to clarify and compare the differences and s
