TNFD C3.0.
For EN/HB: In reporting the core global metric, an organisation should include:
• Known or metered water withdrawal and consumption in addition to listing non-metered sources (e.g. seepage of ground water in tunnels); and
• Water withdrawal from: greywater, blackwater, treated wastewater, desalination plants and other water sources, as well as total water withdrawal and consumption.
This should cover all water purchased and sourced but may include itemisation of water allocated to other parties as the end user. The organisation should differentiate between water withdrawal from groundwater sources that are recharged and non-recharged.
For CM:
In reporting the core global disclosure metric, an organisation should include:
• Total freshwater (≤1000 mg/l of Total Dissolved Solids) withdrawal, including from natural open sources such as rivers, lakes, natural ponds, streams, creeks; from groundwater (wells, boreholes,
water below soil surface); from municipal and/or from third parties; from quarry dewatering used in operations;
• Total non-freshwater (>1000 mg/l of Total Dissolved Solids) withdrawal, including from sources of high salinity or pollutants; and
• Harvested rainwater: Volume of precipitation (rainwater or snowmelt) that is collected onsite (e.g. settling ponds, inactive quarry area that has not yet reached the groundwater table).
Water from quarry dewatering that is not used should be reported separately.
An organisation should differentiate withdrawal from groundwater sources that are recharged and non-recharged.
Utilities, Nuclear & Thermal: In reporting this core global disclosure metric, an organisation should include:
• Water usage for processing, cooling and consumption in powerplants, including use of water in ash handling.
