The work of preparing International Standards is normally carried out through IS0 technical commit

35、tees. 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. IS0 collaborates closely with the In

36、ternational Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISOAEC Directives, Part 3. The main task of technical committees is to prepare International Standards. Draft International

37、Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. In exceptional circumstances, when a technical committee has collected data of a different ki

38、nd from that which is normally published as an International Standard (“state of the art“, for example), it may decide by a simple majority vote of its participating members to publish a Technical Report. A Technical Report is entirely informative in nature and does not have to be reviewed until the

39、 data it provides are considered to be no longer valid or useful. ISO/TR 14049 was prepared by Technical Committee lSO/TC 207, Environmental management, Subcommittee SC 5, Life cycle assessment. iv 63 IS0 2000 - All rights reserved ISO/TR 14049:2000(E) Introduction The heightened awareness of the im

40、portance of environmental protection, and the possible impacts associated with products manufactured and consumed, has increased the interest in the development of methods to better comprehend and reduce these impacts. One of the techniques being developed for this purpose is Life Cycle Assessment (

41、LCA). To facilitate a harmonized approach, a family of standards on life cycle assessment (LCA), including IS0 14040, IS0 14041, IS0 14042 and IS0 14043 and this document are being developed by ISO. These International Standards describe principles of conducting and reporting LCA studies with certai

42、n minimal requirements. This Technical Report provides supplemental information to the International Standard, IS0 14041, Environmental management - Life cycle assessment - Goal and scope definition and life cycle inventory analysis, based on several examples on key areas of the Standard in order to

43、 enhance the understanding of the requirements of the standard. Methodological requirements for conducting LCA studies are provided in the following International Standards concerning the various phases of LCA: - IS0 14040: Environmental management - Life cycle assessment - Principles and framework.

44、 - IS0 14041: Environmental management - Life cycle assessment - Goal and scope definition and inventory analysis. - IS0 14042: Environmental management - Life cycle assessment - Life cycle impact assessment. - IS0 14043: Environmental management - Life cycle assessment - Life cycle intetpretation.

46、Cycle Inventory analysis (LCI) as a means of satisfying certain provisions of IS0 14041. These examples are only a sample of the possible cases satisfying the provisions of the standard. They should be read as offering “a way“ or “ways“ rather than the “unique way“ of applying the standard. Also the

47、y reflect only certain portions of an LCI study. It should be noted that the examples presented in this Technical Report are not exclusive and that many other examples exist to illustrate the methodological issues described. The examples are only portions of a complete LCI study. 2 Technical Introdu

48、ction The examples focus on six key areas of IS0 14041 as indicated in Table 1. In some key areas there is more than one example. The reason is that in many cases more than one practice exists. The decision about the application of one or the other practices is goal dependent and can vary e.g. from

49、the product system under investigation or in the stages over the life cycle. The examples are described in the context of the corresponding provisions of the standard and with the specific use. In the description of the different cases, whenever possible, the following structure has been adopted : - Context of the standard - Overview - Description of the examples 0 IS0 2000 -All rights reserved 1 ISO/TR 14049:2000(E) Table 1 - Cross references between IS8 14041 and examples in this document IS0 14041 0 Introduction 1 Scope 2 Normative reference 3 Terms and definition
