WATER is the Oil of the 21st Century• Oil prices have fallen from their recent peaks, but
concerns about the availability of freshwater show no sign of abating.
• Global water consumption is doubling every 20 years at an unsustainable rate of growth
• Water, unlike oil, has no substitute.• For businesses, water is not discretionary. Without
it, industry and the global economy falter.

Nestlé Perspective on the Water Issue
• Total world-wide freshwater withdrawal: 4 250 000 billion liters (Domestic 10%,Industry 20%,Agriculture 70%, Nestlé 0.004%, Nestlé Waters 0.0009%)
• We are a comparatively small user of water– And are committed to continually reducing our impact – While contributing to overall better water management as the
most effective solution to the water crisis

The Nestlé Commitment to Water Sustainability
• On July 5, 2007, Nestlé Chairman and five other world business leaders launched “The CEO Water Mandate”
• U.N. Global Compact project designed to help companies better manage water use in their direct operations and throughout their supply chains
• Companies pledge to make progress in six areas: – Direct operations– Supply Chain and Watershed management– Collective action– Public policy– Community engagement– Transparency.
• Additionally, they agree to address water shortages and sanitation:– Set water-use targets– Assist suppliers with water-efficiency practices– Partner with governments, policy makers and
community groups

Managing Water Resources for Long-Term Sustainability
Monitoring Our Sources
• Data collected manually and electronically, to manage spring resources
• Balance over the long-term water withdrawal and natural recharge through rain and snowmelt.

Nestlé Progress in Environmental Sustainability: Water
• Since 1998, Nestlé has increased its food production volume by 76%.• Over the same time period we have reduced our water withdrawal by 28%. • Target is to reduce annual consumption per ton of product by 2%-3% over the next five years

Water for AgricultureFrom Water Shortage to Food Shortage
• An Issue of strategic importance for Nestlé……and beyond
• Solutions to overcome water shortage are possible…and urgent:
• No one-dimensional approach

Water for food farming:One liter per calorie
Worldwide average: 3,000 litres of freshwater withdrawn to grow the daily food per person

The Meat Coefficient:
Water required = 10 times the need for plant-based calories and proteins
Animals transform only 5-15% of plant calories into meat.
As a result: water requirement for average diet:
Tunisia 2,964 l/person/day (share of meat in diet : 27%)
California 5,908 l/person/day (meat: 64%)Source: A. Zehnder, Swiss Federal Institute of Aquatic Science and Technology ETHZ 1999

Huge potential for water savings:
Theoretical versus actual freshwater withdrawals for food farming
For example: growing a balanced daily meal, 2,500 Kcal/per capita, 20% meat:
Actual withdrawal of freshwater3000 - 4000 liters
theoretically necessaryto grow this amount of food Potentialin a water-efficient manner for savings1900 liters of freshwater 40%-70%

A Few Solutions
• Improve the efficiency of water use in operations
• Stretch scarce water supplies much further through efficient management and modern technology on the farm
• Collaborate at the local, state and federal level to preserve and protect water sources
• Advocate fair water pricing without price supports to discourage water waste
