Energy Purchased: Total (OI8825)

This metric is intended to capture the amount of energy (both renewable and non-renewable) purchased for use by the organization itself. Adding Energy Generated for Use: Total (OI9624) to this metric should equal the total energy consumed by the organization during the reporting period.

To disaggregate this total by the type of energy purchased—for example, non-renewable vs. renewable sources—report this metric disaggregated by the relevant options from Primary Energy Source (OI3781).

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.
