  2. 2. WATER FOOTPRINT: A CONCEPT RATHER THANA SINGLE METHODOLOGYStill no consensus definition…2“Footprint: a mark of a foot or shoe on a surface”“Water Footprint: environmental impact(s) ofhuman activities on water bodies”
  3. 3. WATER IMPACT INDEX - WIINot an environmental labeling toolNew tool for sustainabilityFor decision makingFor introducing the multi-impact approachFor communicationFor raising awareness
  4. 4. WII– WHAT IS IT?Water can be “consumed” in two ways1. Withdraw and return less2. Pollute – a polluted resource is no resource!An assessment of the human footprint on water resources takinginto account consumption, resource stress and quality.

  7. 7. WII: HOW IS IT CALCULATED?WII= Water Stress Index * ((Volume Extracted * Quality Index ) – (Volume Released * Quality Index))or Difference between the quality of the water(abstracted or discharged) and WaterQuality Standards for the water bodyCalculated for the “most penalizing”pollutant7
