Organizations should footnote all assumptions used. See usage guidance for further information.
This metric is intended to capture the amount of hazardous waste the organization’s operations create during the reporting period, defined as refuse that could present dangers by contaminating and polluting the environment. Hazardous waste requires special disposal techniques to make it harmless or less dangerous. Specific classification of hazardous waste, which organizations should footnote, is typically defined by local legislation.
Organizations are also encouraged to footnote the methods employed to ensure that hazardous waste is disposed of responsibly.
