3. 1. SCOPE
Scope:
Only air and soil emissions that impact water quality are included in
the assessment and not all air and soil emissions are included.
ISO 14046 standard is based in the next concepts:
→ LIFE CYCLE ASSESSMENT (LCA)
→ WATER FOOTPRINT IMPACT ASSESSMENT (WFIA)

5. METHODOLOGICAL FRAMEWORK: LCA&WFIA relation
8. The Water Footprint Inventory Analysis stage of an LCA is useful to:
Compilation and quantification of inputs and outputs (water,
energy, raw materials, auxíliary materials, heat, fuels, co-products)
and the potential environmental impacts of a product system
and consequently
Stablishment of material, water and energy balances throgouth its
life cycle and its process

the organization)
Secondary data (when a lack of primary data, coming from
bibliography, suppliers, consolidated sources, other organizations
up/down streams and other sources)
Input data for calculation software (if any)
Data quality (representativeness, accuracy, precision, uncertainty)

5. METHODOLOGICAL FRAMEWORK: INVENTORY
13. Some water footprint references finalize their requirements at the end
of this phase. Consequently Water Footprint Reports inform about
different types of waters. Impacts associated are not reported.
Proceedings:
1. Data determination and selection
2. Software selection for calculations (if any) or spreadsheets
3. Balance calculation of water, energy, raw materials, etc.
4. Data relating to functional unit (if WF for products)
5. Associated impacts (if required by the reference applied)
6. Water footprint reporting performance

stand-alone assessment (i.e. only black
boxes) or part of a life cycle assessment
(i.e. entire life cycle impact assessment
phase in grey boxes)
5. METHODOLOGICAL FRAMEWORK: IMPACT ASSESSMENT
16. a) General aspects: who is the commissioner or practitioner of the study (internal
or external), date of report, and statement that the study has been conducted
according to the requirements of this International Standard.
b) Goal of the study: reasons for the study, its intended applications, the target
audiences, study as a stand-alone assessment or a part of a LCA, and whether
comparative assertion is intended.
c) Scope of the study: function, functional unit, system boundaries, input/output
cut- off criteria, product, unit processes and stages of a WF LCA
d) Water footprint inventory analysis
e) Water footprint impact assessment
6. REPORTING
16
17. f) Interpretation: of results, conclusions, assumptions and limitations both to
data and methodologies, data quality, value choices, rationales and expert
judgments, positive aspects, etc.
The results obtained by standard application can be expressed with a single
impact indicator or a as group of them. The standard offers multiple possibilities
to present and communicate results.
17
6. REPORTING
18. Optional. Only mandatory when the WF Report is intended to be used for a
comparative assertion.
Critical review is performed by:
internal or external expert or panel of interested parties
expert independent of the water footprint assessment team
7. CRITICAL REVIEW
18
20. ISO 14046:2014 standard can be applied to different boundaries:
Organizations: number and type of locations (office buildings, trade
centers, construction work sites, soils, industrial plants, etc.)
Products/services: with mention to the locations for each product process
and its associated functional units
20
ANNEX A: ADDITIONAL CONSIDERATIONS FOR ORGANIZATIONS
21. WF Reporting is a useful tool that contributes to:
efficiency in the water management for products and organizations in
the climate change frame of reference
create lower water consumption of products and services market as an
answer to the current social demands
Identify saving oportunities in the organizations due to the strong
relation between energy and water management
explain comprimises of social responsibility to third parts related with
the adaptation to climate change frame of reference

22. NEW DEVELOPING WATER FOOTPRINT ISO STANDARDS
Currently, is being developed the standard ISO/TR 14073, with several
case studies for ISO 14046, by the same WG that performed the ISO
14046 Standard, in the ISO 207 Technical Comeetee.
Publishing is expected for the last months of 2016 or first quarter of
2017
