Greenhouse Gas Emissions of Product (PD9427)

This metric is intended to capture the potential GHG emissions of a product during its usable lifetime. Its calculation should not include GHG emissions related to a product’s manufacture or transport.

Organizations that wish to report GHG emissions reduced as a result of a product can report against Greenhouse Gas Reductions Due to Products Sold (PI5376).

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)

In some circumstances, this metric can help describe the CONTRIBUTION an organization likely had to the degree of change (depth) in outcome that the stakeholders experienced, relative to what the market or social system would have done anyway. 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.
