6. Motivation for
assessing a
Water Footprint
• Water scarcity is one of the most important
environmental problems
• Increasing population is aggravating water
problems
• Sustainability has become a key marketing factor
• Public pressure and operational risk make it
relevant for business to assess physical,
regulatory and reputational risks (beyond “green
pioneers”)

the water footprint is
determined by one or more

potential
environmental impact
on water of a product,
process or organization.
