Usage Guidance
-
This metric is intended to capture the total amount of greenhouse gas emissions that were reduced by the organization during the reporting period.
-
This metric should be used in combination with Greenhouse Gas Emissions Mitigation Types (OI9839) in order to disaggregate the types of greenhouse gas emissions reductions relevant to the organization's activities.
-
Calculating greenhouse gas emissions reductions is a technical process and should be done in alignment with an accepted standard, such as the American Carbon Registry or GHG Protocol.
-
This metric is multi-dimensional with regard to the five dimensions of impact. 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). It may also help measure the HOW MUCH Scale dimension, which helps estimate the number of the targeted stakeholders experiencing the outcome. For more on the alignment of IRIS metrics to the five dimensions of impact, see specific guidance document. 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.

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).
