Kern der Offenlegung
Disclosure 303-3 requires an organization to report total water withdrawal from all areas and separately from all areas with water stress, in megaliters. Water withdrawal is classified as surface water, groundwater, seawater, produced water or third-party water. Collected rainwater is classified as surface water, while municipal and utility water is classified as third-party water.
For every applicable source, the organization reports the volume of freshwater, defined as water with total dissolved solids of 1 000 mg/L or less, and other water, defined as water with total dissolved solids above 1 000 mg/L.
For third-party water withdrawn in areas with water stress, the organization additionally reports the original source used by the supplier: surface water, groundwater, seawater or produced water. The organization requests this information from the third-party supplier.
Areas with water stress are identified using publicly available and credible tools or methodologies, with assessment conducted at least at catchment level. The methodology, tool version, thresholds, assumptions and limitations are disclosed.
Internally recycled or recirculated water is not counted as a new withdrawal. It can be reported separately as additional information on water reuse.
GRI additionally recommends reporting source-level withdrawal for each facility in areas with water stress and the total water withdrawal of suppliers with significant water-related impacts in such areas. These are recommendations and should be distinguished from the mandatory requirements.
