Frequently Asked Questions
How has this credit changed from STARS 2.1 to 2.2?
Substantive changes have been made to this credit. The revamped credit now includes an institution’s greenhouse gas and air pollutant emissions inventories. A comprehensive list of differences can be found in the 2.2 Summary of changes.
What information is required in the GHG inventory?
Uploaded inventory should provide clear indication of Scope 1, 2 and 3 emissions. If indicating that certain Scope 3 emissions are included, then the inventory must reflect this. Otherwise, Scope 3 responses should be updated to “None” as appropriate.

Common Issues Identified During Review
- Part 1: Uploaded inventory should provide clear indication of Scope 1, 2 and 3 emissions. If indicating that certain Scope 3 emissions are included, then the inventory must reflect this. Otherwise, Scope 3 responses should be updated to “None” as appropriate.
- If indicating that the inventory has been verified by an independent, external third party or validated internally by independent personnel, descriptive response and/or upload must support verification of the inventory by an external party.
