Average volume of water utilization/consumption over the lifetime of the product based on the planned operation of the product/system.
Organizations should footnote assumptions made with respect to product utilization/consumption.
This metric is intended to capture lifetime water consumption of an individual product and not water consumption of products sold within the reporting period. For example, this metric may be used to measure the water consumption of a low-flow toilet.

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).
