### Footnote

Organizations should footnote all assumptions used.

### Usage Guidance

• This metric is intended to capture the GHG emissions reduced/mitigated due to the organization's products sold. The lifetime reduction in greenhouse gas emissions is calculated by subtracting the Greenhouse Gas Emissions of Product Replaced (PD2243) minus the Greenhouse Gas Emissions of Product (PD9427). This is then multiplied by the units/volume sold to get the total reductions over the lifetime of the product, for all products sold during the reporting period.
• When multiplying the greenhouse gas reductions due to each product sold by Units/Volume Sold: Total (PI1263), organizations should use absolute number of units rather than volume. For example, if the greenhouse gas reductions due to each product (e.g., solar panel) is multiplied by each unit of solar panel unit sold, the total greenhouse gas reductions due to products sold can be calculated.
• 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 can refer to:
