21、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 has the right to be represented on that committee. I

22、nternational 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.The procedures used to develop this document and those

23、intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see

27、al management, Subcommittee SC 5, Life cycle assessment.iv ISO 2014 All rights reservedBS EN ISO 14046:2016 EN ISO 14046:2016 (E)IntroductionWater is an essential natural resource.The issue of water and its management has become increasingly central to the global debate on sustainable development. T

28、his interest has been driven by growing water demand, increasing water scarcity in many areas and/or degradation of water quality. This drives the need for a better understanding of water related impacts as a basis for improved water management at local, regional, national and global levels.It is th

29、erefore desirable to have appropriate assessment techniques that can be used in an internationally consistent manner.One of the techniques being developed for this purpose is the water footprint assessment.There is a growing demand for assessing and reporting water footprints. Various methodologies

30、exist to do so and currently these methodologies emphasise different aspects related to water. There is therefore a need to ensure consistency in assessing and reporting water footprints.This International Standard is expected to benefit organizations, governments and other interested parties worldw

31、ide by providing transparency, consistency, reproducibility and credibility for assessing and reporting the water footprint of products, processes or organizations.A water footprint assessment conducted according to this International Standard: is based on a life cycle assessment (according to ISO 1

32、4044); is modular (i.e. the water footprint of different life cycle stages can be summed to represent the water footprint); identifies potential environmental impacts related to water; includes relevant geographical and temporal dimensions; identifies quantity of water use and changes in water quali

33、ty; utilizes hydrological knowledge.A water footprint assessment can assist in:a) assessing the magnitude of potential environmental impacts related to water;b) identifying opportunities to reduce water related potential environmental impacts associated with products at various stages in their life

34、cycle as well as processes and organizations;c) strategic risk management related to water;d) facilitating water efficiency and optimization of water management at product, process and organizational levels;e) informing decision-makers in industry, government or non-governmental organizations of the

35、ir potential environmental impacts related to water (e.g. for the purpose of strategic planning, priority setting, product or process design or redesign, decisions about investment of resources);f) providing consistent and reliable information, based on scientific evidence for reporting water footpr

36、int results.A water footprint assessment alone is insufficient to be used to describe the overall potential environmental impacts of products, processes or organizations.The water footprint assessment according to this International Standard can be conducted and reported as a stand-alone assessment,

37、 where only impacts related to water are assessed, or as part of a life cycle ISO 2014 All rights reserved vBS EN ISO 14046:2016 EN ISO 14046:2016 (E)assessment, where consideration is given to a comprehensive set of environmental impacts and not only impacts related to water.In this International S

38、tandard, the term “water footprint” is only used when it is the result of an impact assessment.The specific scope of the water footprint assessment is defined by the users of this International Standard in accordance with its requirements.NOTE 1 In this International Standard, the term “product” inc

39、ludes services.NOTE 2 In this International Standard, the term “environmental impacts” includes categories generally found in impact models used in life cycle assessment, such as impacts on ecosystems, on human health and on resources.NOTE 3 Reporting is different from communication. Requirements an

40、d guidelines for reporting are included in this International Standard, but requirements and guidelines for communication, such as environmental labels or declarations, are outside the scope of this International Standard.vi ISO 2014 All rights reservedBS EN ISO 14046:2016 EN ISO 14046:2016 (E)INTER

41、NATIONAL STANDARD Environmental management Water footprint Principles, requirements and guidelines1 ScopeThis International Standard specifies principles, requirements and guidelines related to water footprint assessment of products, processes and organizations based on life cycle assessment (LCA).T

42、his International Standard provides principles, requirements and guidelines for conducting and reporting a water footprint assessment as a stand-alone assessment, or as part of a more comprehensive environmental assessment.Only air and soil emissions that impact water quality are included in the ass

43、essment, and not all air and soil emissions are included.The result of a water footprint assessment is a single value or a profile of impact indicator results.Whereas reporting is within the scope of this International Standard, communication of water footprint results, for example in the form of la

44、bels or declarations, is outside the scope of this International Standard.NOTE Specific requirements and guidelines for organizations are given in Annex A.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its app
