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
Where do we stand?
