Water Savings from Products Sold (PD5786)

This metric is intended to capture the product-lifetime water savings to consumers from their purchase of the organization’s water-efficient products.

When multiplying the savings from each product sold by Units/Volume Sold: Total (PI1263), organizations should, under Units/Volume Sold: Total (PI1263), use the absolute number of product units sold rather than the volume of savings delivered by the product.

In some contexts, this metric can serve as an indicator of whether the outcome being sought by an investor or organization is occurring (the WHAT dimension of impact). For more on the alignment of IRIS metrics to the five dimensions of impact, see IRIS+ and the Five Dimensions of Impact (https://iris.thegiin.org/document/iris-and-the-five-dimensions/). No single metric is sufficient to understand an impact; rather, metrics are selected as a set across all dimensions of impact. When possible, the selection of metrics to measure and describe the five dimensions should be based on best practice and evidence.
