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”)

Starting in 2009 ≈ 80 experts-delegates (from all continents) 9

9 working meetings (Sweden, Mexico, Switzerland, Norway, Brazil, Thailand, Italy, Bostwana, Panama) to deliver a consensual International Standard on « water footprinting » 10

the water footprint is determined by one or more 5. Aplicaciones directas: metrics that quantify the Propuestas de mejora 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 500 ml – 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.
