In parallel with carbon management and reporting, water reporting is emerging as a headline indicator at a corporate level. Normally the water use reported at corporate level considers direct water use only. However water foot-printing is now starting to be an emerging trend and clients are requesting that contractors consider the water footprint of the construction site – or the embodied water of the materials used on site.
Traditionally embodied water refers to the cumulative quantity of water used to produce a product through the supply chain.

* Note that current methodologies for calculating embodied water do not assess water scarcity or quality issues.
