Retail GHG Emissions Factors, Data & Methodology

This matrix provides a summary of some sources for greenhouse gas (GHG) emissions factors, data and methodology relevant to retailers who are developing a company GHG inventory, as aligned with the GHG Protocol scope categories. Please note this list is not exhaustive and is a working document.

Thank you to RILA members and EPA’s Center for Corporate Climate Leadership for reviewing and providing suggestions!

Note about “Retail Relevance” -- While a category may be potentially relevant to all retailers, each organization should undergo a relevance assessment (as described in scope 3 GHG Protocol methodologies) to determine which sources should be reported.
