Where do we stand?
- Water footprint will become a new global KPI. Method is still
developing.
- The impact analysis deserves more emphasis: a high water footprint is not a problem in itself.
- Need for international standards to be developed with the Water
Footprint Network
DHV combines existing knowledge in water footprint projects.
- DHV searches for solutions that create ‘added value’, which is more appealing to our clients than ‘reduction and mitigation measures’ as proposed by the Water Footprint Network
