Environmental management - Water footprint - Principles, requirements and guidelines (ISO 14046:2014)
ISO 14046:2014 specifies principles, requirements and guidelines related to water footprint assessment of products, processes and organizations based on life cycle assessment (LCA).
ISO 14046:2014 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 assessment, 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 ISO 14046:2014, communication of water footprint results, for example in the form of labels or declarations, is outside the scope of ISO 14046:2014.
Umweltmanagement - Wasser-Fußabdruck - Grundsätze, Anforderungen und Leitlinien (ISO 14046:2014)
Diese Internationale Norm legt Grundsätze, Anforderungen und Leitlinien im Zusammenhang mit der Ermittlung des Wasser-Fußabdrucks von Produkten, Prozessen und Organisationen auf der Grundlage einer Ökobilanz fest.
Diese Internationale Norm stellt Grundsätze, Anforderungen und Leitlinien zur Durchführung und Berichterstattung einer Ermittlung des Wasser-Fußabdrucks als eigenständige Untersuchung oder als Teil einer umfassenderen umweltbezogenen Analyse zur Verfügung.
In die Ermittlung werden nur die Emissionen in Luft und Boden einbezogen, die sich auf die Wasserqualität auswirken, und nicht sämtliche Emissionen in Luft und Boden.
Das Ergebnis einer Ermittlung des Wasser-Fußabdrucks ist ein einzelner Wert oder ein Profil von Wirkungsindikatorwerten.
Während die Berichterstattung im Anwendungsbereich dieser Internationalen Norm enthalten ist, fällt die Kommunikation von Wasser-Fußabdruckwerten, zum Beispiel in Form von Kennzeichnungen oder Deklarationen, nicht in den Anwendungsbereich dieser Internationalen Norm.

Introduction
Water is an essential natural resource.
The issue of water and its management has become increasingly central to the global debate on sustainable
development. This 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 therefore 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 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 worldwide 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 14044);
— 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 quality;
— 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 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 their
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
footprint 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, where only impacts related to water are assessed, or as part of a life cycle

assessment, where consideration is given to a comprehensive set of environmental impacts and not only
impacts related to water.In this International Standard, 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” includes 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 and 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 reserved

Principles, requirements and guidelines
1 Scope
This International Standard specifies principles, requirements and guidelines related to water footprint
assessment of products, processes and organizations based on life cycle assessment (LCA).
This 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 assessment, 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 labels or declarations, is outside the scope of this International
Standard.NOTE Specific requirements and guidelines for organizations are given in Annex A.

3 Terms and definitionsFor the purposes of this document, the following terms and definitions apply.
3.1 Terms relating to types and classifications of water
3.1.1
freshwater
water having a low concentration of dissolved solids
Note 1 to entry: Freshwater typically contains less than 1 000 mg/l of dissolved solids and is generally accepted
as suitable for withdrawal and conventional treatment to produce potable water.Note 2 to entry: The concentration of total dissolved solids can vary considerably over space and/or time.
3.1.2brackish water
water containing dissolved solids at a concentration less than that of seawater (3.1.4), but in amounts
that exceed normally acceptable standards for municipal, domestic and irrigation uses
Note 1 to entry: The concentration of total dissolved solids in brackish water can vary from 1 000 mg/l to
30 000 mg/l.© ISO 2014 – All rights reserved 1
---------------------- Page: 13 ----------------------
SIST EN ISO 14046:2016
ISO 14046:2014(E)
Note 2 to entry: The concentration of total dissolved solids of many brackish waters can vary considerably over
space and/or time.3.1.3
surface water
water in overland flow and storage, such as rivers and lakes, excluding seawater (3.1.4)
3.1.4seawater
water in a sea or an ocean
Note 1 to entry: Seawater has a concentration of dissolved solids greater than or equal to 30 000 mg/l.
3.1.5groundwater
water which is being held in, and can be recovered from, an underground formation
[SOURCE: ISO 11074:2005, 3.2.2, modified — Note has been removed.]3.1.6

entity of water with definite hydrological, hydrogeomorphological, physical, chemical and biological
characteristics in a given geographical areaEXAMPLE Lakes, rivers, groundwaters, seas, icebergs, glaciers and reservoirs.
Note 1 to entry: In case of availability, the geographical resolution of a water body should be determined at the
goal and scope stage: it may regroup different small water bodies.3.1.8
drainage basin
area from which direct surface runoff from precipitation drains by gravity into a stream or other water
body (3.1.7)Note 1 to entry: The terms “watershed”, “drainage area”, “catchment”, “catchment area” or “river basin” are
sometimes used for the concept of “drainage basin”.Note 2 to entry: Groundwater drainage basin does not necessarily correspond in area to surface drainage basin.
Note 3 to entry: The geographical resolution of a drainage basin should be determined at the goal and scope stage:
it may regroup different sub drainage basins.3.1.9

compilation and evaluation of the inputs, outputs and the potential environmental impacts related to
water used or affected by a product, process or organizationNote 1 to entry: In this International Standard, the term “study” is often used as synonym for “water footprint
assessment”.3.3.3
comprehensive water footprint assessment
water footprint assessment (3.3.2) that fulfils the principle of comprehensiveness
Note 1 to entry: The principle of comprehensiveness implies to consider all environmentally relevant attributes
or aspects of natural environment, human health and resources related to water, including water availability
