This metric is looking for the percentage of the water used by the company was recycled or reused in cubic metres:
For WikiRate researchers:
Companies who align reports to GRI’s Sustainability Reporting Standards often include a GRI Content Index or Annex where GRI disclosures, with GRI codes, are listed.
Use the GRI Index, CTRL F, Command F or search button on source window to search for this index and metrics within the report
Use G4 codes, G3 codes or keywords to quickly find values, keeping in mind that some companies report on the metric using different terms, e.g. G4-EN10 or EN10, water recycled or water reused
Always check the metric question and methodology for the unit of measure or currency - researchers may need to carry out calculations or conversions before entering the final metric value
Add comments documenting exactly where within the source you found the information (page number) and include details of simple or complex calculations or conversions made to determine the metric value
If you are unable to locate a metric value in a source you can search for additional sources where the data is available and add a new source
Further guidance on how to research values for GRI-based metrics is available here, including detailed guidance on adding, editing and Checking metric values.
Global Reporting Initiative compliance guidance for companies:
To calculate Water Recycled (%) - G4-EN10-b:
For example, if the organization has a production cycle that requires 20 cubic meters of water per cycle, the organization withdraws 20 cubic meters of water for one production process cycle and then reuses it for an additional three cycles. The total volume of water recycled and reused for that process is 60 cubic meters.
Reporting on this Indicator should include the following contextual information as a comment to the metric value:
Note: Due to the way this is calculated, where water can be re-used multiple times, it is possible for a company’s recycling rate to be recycle greater than 100%, and at least one company has reported such a rate.
