Суть раскрытия

Disclosure 303-4 requires an organization to report total water discharge to all areas in megaliters and break this total down by destination: surface water, groundwater, seawater and third-party water. Where any third-party water is sent to other organizations for use, that volume is included in total third-party water and reported separately as a subset.

The organization also reports total water discharge by water quality. For all areas and for all areas with water stress, it reports 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.

Areas with water stress are identified using publicly available and credible tools or methodologies. The organization explains the tool, geographic resolution, threshold, assessment date and assumptions used.

The organization reports the priority substances of concern for which discharges are treated, explains how those substances were defined and identifies any international standard, authoritative list or criteria used. It also explains how discharge limits were set and reports the number of incidents of non-compliance with those limits.

The number of incidents of non-compliance is distinct from the recommended number of occasions on which limits were exceeded. Where both are reported, the counting methodologies should be explained.

GRI additionally recommends reporting discharge by level of treatment and the percentage of suppliers with significant water-discharge impacts that have established minimum effluent-quality standards beyond regulatory requirements.
