Amount of hazardous waste created by the organization's operations during the reporting period.
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.
This is a submetric of Waste Produced: Total (OI6709), which has 3 other related submetrics.
Metrics identified as "cross-category" are those that are relevant to any IRIS+ Impact Category or Impact Theme (i.e., these metrics are not specific to any particular industry/category or theme).

IRIS Metrics Work Better in Sets
To use IRIS metrics—and the resulting data—to understand impact performance, IRIS metrics should be used and analyzed in generally accepted sets and according to well-defined objectives. IRIS+ gives you access to generally accepted Core Metrics Sets aligned to common Impact Themes and Sustainable Development Goals (SDGs).
