Amount of toxic materials used in the organization's manufacturing processes during the reporting period.
Organizations should footnote all assumptions used.
This metric is intended to capture the level of toxicity present in the organization’s manufacturing processes.
Organizations are encouraged to align their reporting to international standards. For example, the European Union Regulation for Registration, Evaluation, Authorization, and Registration of Chemicals (REACH) requires companies to provide information across the industrial supply chain about the risks posed by substances, as well as how they should be handled. This information on the safe use of substances is transmitted along the industrial supply chain to help reduce risks for workers, consumers, and the planet.

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).
