Increased Awareness
2009 Globescan 32,000 people in 15 countries found:
– 90% perceived as serious problems– 78 % said that companies have a
clear role and obligation to find solutions

Why Businesses are Interested
• Financial Risk– Costs– Revenues
5
• Physical Risk– Scarcity, quality
• Regulatory Risk– Change in rules
less availability, loss of license
• Reputational Risk– Loss of market

Elements of Water Stewardship Frameworks
1. Water use accounting– Withdrawals, discharge, consumption– Supply chain, direct, and end use
2. Impacts assessment– Access to human or aquatic life– Impaired quality
3. Business Risks– Shortages & costs– Regulation– Managment
4. Prevention & response– Conservation, management, and reuse– Watershed improvements
5. Public Communication & Disclosure

Carbon Disclosure ProjectWater Disclosure• Parallel to carbon disclosure• Focus on investment community
– Disclosure of risks– Opportunities for business
• Detailed questionnaire– uses– discharge– risk– strategic
– condition– recycle– opportunity– management
![Page 15: Sustainable Water Resources Roundtable Meeting](https://reader035.vdocuments.us/reader035/viewer/2022062521/56816883550346895ddf0232/html5/thumbnails/15.jpg)
• Standardize sustainability reporting• Example water reports
– EN 8 water withdrawal by source– EN 9 water sources affected by withdrawal– EN 10 water recycled/reused– EN 21 water discharged (quantity, quality,
destination)– EN 23 impact of spills– EN 25 biodiversity of water bodies– EN 28 fines

Chapter 5.10 Water Consumption*****’s power distribution business operations do not interfere with the wetlands listed by the Ramsar Convention (1971) which addresses the preservation and rational use of wetlands, nor does its water consumption significantly affect ecosystems/natural habitats. In terms of industrial power generation, the water from the reservoirs, which only passes through turbines is not considered consumed water.
***’s power plants employ water from rivers, lakes and reservoirs for cooling in an open circuit without any recirculation.
**** does not recycle the water used in the administrative facilities. The water consumption by the administrative facilities in 2008 was, 545,905 m3 with a 2.0% reduction compared to 2007.

ISO 14046 Water Footprint
• Parallel to carbon footprint• Consistent with life cycle
assessment• “footprint” with weighting factors to
produce “score”• Under development

Alliance for Water Stewardship
• Certification program• Initiated by multi stakeholder groups
of global NGOs• Parallel to FSC, MSC certification• Focus on industry• Builds a regional efforts by EWP
and WSI• Elaborate stakeholder input• Under development

SummaryWater Stewardship Initiative
• Many tools & approaches• Different roots & objectives• Different capabilities & applications• No one tool does it all• Field & tools under development
