Greenhouse Gas Emissions Mitigated (OI5951)

This metric is intended to capture the total amount of GHG emissions mitigated during the reporting period: the sum of GHG emissions sequestered and avoided or reduced by the organization during the reporting period.

To disaggregate by type of GHG emissions mitigation, organizations are encouraged to report Greenhouse Gas Emissions Mitigation Types (OI9839) and, as applicable, Greenhouse Gas Emissions Sequestered (PI9878) and Greenhouse Gas Emissions Avoided or Reduced (PI2764). All such metrics should include GHG emissions reductions from both direct and indirect sources.

This metric should be a number representing the organization's total mitigation of carbon. To understand the organization's net carbon emittance, subtract this metric from Greenhouse Gas Emissions: Total (OI1479).

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 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.
