22、ion 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 h
23、as 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. Int
24、ernational Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Public
25、ation as an International Standard requires approval by at least 75 % of the member bodies casting a vote.

This second edition of ISO 14040, together with ISO 14044:2006, cancels and replaces ISO 14040:1997, ISO 14041:1998, ISO 14042:2000 and ISO 14043:2000, which have been
27、technically revised. EN ISO 14040:2006vIntroduction The increased awareness of the importance of environmental protection, and the possible impacts associated with products 1), both manufactured and consumed, has increased interest in the development of methods to better understand and address these
28、 impacts. One of the techniques being developed for this purpose is life cycle assessment (LCA). LCA can assist in identifying opportunities to improve the environmental performance of products at various points in their life cycle, informing decision-makers in industry, government or non-government
29、 organizations (e.g. for the purpose of strategic planning, priority setting, product or process design or redesign), the selection of relevant indicators of environmental performance, including measurement techniques, and marketing (e.g. implementing an ecolabelling scheme, making an environmental
30、claim, or producing an environmental product declaration). For practitioners of LCA, ISO 14044 details the requirements for conducting an LCA. LCA addresses the environmental aspects and potential environmental impacts 2)(e.g. use of resources and the environmental consequences of releases) througho
31、ut a products life cycle from raw material acquisition through production, use, end-of-life treatment, recycling and final disposal (i.e. cradle-to-grave). There are four phases in an LCA study: a) the goal and scope definition phase, b) the inventory analysis phase, c) the impact assessment phase,
32、and d) the interpretation phase. The scope, including the system boundary and level of detail, of an LCA depends on the subject and the intended use of the study. The depth and the breadth of LCA can differ considerably depending on the goal of a particular LCA. The life cycle inventory analysis pha
33、se (LCI phase) is the second phase of LCA. It is an inventory of input/output data with regard to the system being studied. It involves collection of the data necessary to meet the goals of the defined study The life cycle impact assessment phase (LCIA) is the third phase of the LCA. The purpose of
34、LCIA is to provide additional information to help assess a product systems LCI results so as to better understand their environmental significance. 1) In this International Standard, the term “product” includes services. 2) The “potential environmental impacts” are relative expressions, as they are
35、related to the functional unit of a product system. EN ISO 14040:2006vi Life cycle interpretation is the final phase of the LCA procedure, in which the results of an LCI or an LCIA, or both, are summarized and discussed as a basis for conclusions, recommendations and decision-making in accordance wi
36、th the goal and scope definition. There are cases where the goal of an LCA can be satisfied by performing only an inventory analysis and an interpretation. This is usually referred to as an LCI study. This International Standard covers two types of studies: life cycle assessment studies (LCA studies
37、) and life cycle inventory studies (LCI studies). LCI studies are similar to LCA studies but exclude the LCIA phase. LCI studies are not to be confused with the LCI phase of an LCA study. Generally, the information developed in an LCA or LCI study can be used as part of a much more comprehensive dec
38、ision process. Comparing the results of different LCA or LCI studies is only possible if the assumptions and context of each study are equivalent. Therefore this International Standard contains several requirements and recommendations to ensure transparency on these issues. LCA is one of several env
39、ironmental management techniques (e.g. risk assessment, environmental performance evaluation, environmental auditing, and environmental impact assessment) and might not be the most appropriate technique to use in all situations. LCA typically does not address the economic or social aspects of a prod
40、uct, but the life cycle approach and methodologies described in this International Standard can be applied to these other aspects. This International Standard, like other International Standards, is not intended to be used to create non-tariff trade barriers or to increase or change an organizations
41、 legal obligations. EN ISO 14040:20061Environmental management Life cycle assessment Principles and framework 1 Scope This International Standard describes the principles and framework for life cycle assessment (LCA) including a) the goal and scope definition of the LCA, b) the life cycle inventory
42、analysis (LCI) phase, c) the life cycle impact assessment (LCIA) phase, d) the life cycle interpretation phase, e) reporting and critical review of the LCA, f) limitations of the LCA, g) relationship between the LCA phases, and h) conditions for use of value choices and optional elements. This Inter
43、national Standard covers life cycle assessment (LCA) studies and life cycle inventory (LCI) studies. It does not describe the LCA technique in detail, nor does it specify methodologies for the individual phases of the LCA. The intended application of LCA or LCI results is considered during the goal
44、and scope definition, but the application itself is outside the scope of this International Standard. This International Standard is not intended for contractual or regulatory purposes or registration and certification. 2 Normative references The following referenced documents are indispensable for
