Sustainability - Waterfoot print standard coming soon

Water use and management have become central to the global debate on sustainability. Sustainability experts can look forward to more help from ISO. A new standard ISO 14046 coming up soon to help standardise the approach to calculating and implementing sustainability initiative through a systematic management of watr footprint. 

What is a water footprint assessment?

According to ISO 14046, a water footprint assessment:

• Relies on a life-cycle assessment
• Is modular (that is, the different life-cycle stages of the water footprint can be summed up to represent the water footprint)
• Identifies potential environmental impacts related to water
• Includes relevant geographical and temporal dimensions
• Identifies the quantity of water used and changes in water quality
• Utilizes existing hydrological knowledge
