Water
Key element for humans
for household, agricultural and industrial activities
affects human health through hydrical diseases
Key element for ecosystems
Conserve resource for future generations
3rd UN World Water Development Report (2009) Scarcity - low
available water per capita – is forecast to worsen
where population growth is still high, as in sub-Saharan
Africa,
South Asia and some countries in South America and the
Middle
East

Framework proposed and agreed in Léon
If needed
(“water footprint = shoe size * weight” – WBCSD Montreux
workshop key learning)
•ISO & LCA is not about providing a single number!
•It is about helping you identifying where, throughout your
product chain or worlwide activities, are issues related to water
use,
and, IF NEEDED, providing a consistent framework to provide a
single number

Summary prior working meetings
19-21 November 2009, Stockholm, Sweden
11-14 July 2010, Léon, Mexico
24-26 January, Lausanne, Switzerland
Decisions:
Water footprint
Product & organization
Aligned with ISO 14040/44 :
broad range of water use (and not only water consumption)
include indirect water use (aligned with carbon footprint)
includes impact assessment (not only inventory); considering
local conditions (water stress, etc.)
stand-alone method (e.g., labeling) as well as part of a
comprehensive LCIA (be careful about
double counting)
critical review for active comparative assertion
(terminology, etc.)
Suggested but no firm decision made yet:
include suggested characterization factors (e.g., for labeling)
in Annex/Appendix/Technical
document
