  • Organizations that wish to report the GHG emissions reduced due to the product can report against Greenhouse Gas Reductions due to Products Sold (PI5376).
  • Organizations should refer to the following sources for further guidance:
    - WRI Greenhouse Gas Protocol Standards (
    - International Panel on Climate Change (IPCC) emission factors (
    - Global Reporting Initiative (GRI) (
    - CDM Methodologies (
  • Calculations should be made leveraging GHG Protocol guidelines/methodologies to the extent possible.
