“ Sustainable resource management of
freshwater and energy holds the key to
Sustainable Development”

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 metrics that quantify the potential environmental impact on water of a product, process or organization.
Water footprint of Mexican Beer
• Monthly data (aprox. 25 companies 1994 to 2009)
• Packaging materials (INEGI, 2009)
– 94% up to 500ml– 53% bottles are returnable– 22% non returnable– 25% aluminium cans
• Disposal (Semarnat, 2008)– 24.1% aluminium is recycled– 17.8% glass is recycled– 8.5% cardboard is recycled
• Agricultural data from Mexico• Use: 2.7 Wh/Lt (3 days in freezer)
Farell,C., Turpin, S., Suppen, N., 2012, Water footprint of Mexican Beer.
36% volume of water use is due to crops
16% volume of water is due to packaging
98.98% of water used in the process is groundwater
