Greenhouse Gas Reductions due to Products Sold (PI5376)

This metric is intended to capture the GHG emissions reduced or mitigated as a result of products the organization sold during the reporting period. The product-lifetime reduction in GHG emissions is calculated by subtracting Greenhouse Gas Emissions of Product (PD9427) from Greenhouse Gas Emissions of Product Replaced (PD2243). This is then multiplied by the units/volume sold per product to get the total GHG reductions over the lifetime of the product(s). These GHG reductions are then summed across all products sold during the reporting period.

When multiplying GHG reductions 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 GHG reductions delivered by the product.

The Greenhouse Gas Protocol (GHG Protocol) is the most widely used international accounting tool to understand, quantify, and manage greenhouse gas emissions. For more information on the GHG Protocol, organizations should refer to the following:

• Greenhouse Gas Protocol Standards (http://www.ghgprotocol.org/standards)
• Greenhouse Gas Protocol Calculators (https://ghgprotocol.org/calculation-tools)

This metric is multi-dimensional with regard to the five dimensions of impact. In specific contexts, and based on evidence, this metric may serve as a proxy 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 Depth dimension of impact, which helps estimate the degree of change in outcome that the stakeholders experienced. 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.
