Part 1. Greenhouse gas emissions inventory

Has the institution conducted a GHG emissions inventory within the previous three years that includes all Scope 1 and 2 emissions? :
Yes

A copy of the most recent GHG emissions inventory:
A brief description of the methodology and/or tool used to complete the GHG emissions inventory:
We have developed and refined a spreadsheet-based calculator for our own use. This was initially modelled after the CACP calculator, but we have refined it over the years to improve upon the emission factors and limit the entries to those that are relevant to our campus. EFs from the US EPA EF hub and the WRI GHG protocol are reviewed every year and updated as appropriate. Details are included in the GHG inventory report.

Has the GHG emissions inventory been validated internally by personnel who are independent of the GHG accounting and reporting process and/or verified by an independent, external third party?:
No

A brief description of the GHG inventory verification process:
N/A

Documentation to support the GHG inventory verification process:
