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:
UC San Diego uses The Climate Registry General Protocol and CRIS Reporting tool for Scope 1 and 2 emissions. Commuting emissions are calculated using survey data from Transportation Services/Commute Solutions. Business Air Travel emissions are calculated using the campus air miles traveled from Connexxus and the formula from AASHE and UNH SIMAP (formerly the Clean Air - Cool Planet Campus Carbon Calculator).
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?:
Yes
A brief description of the GHG inventory verification process:
UC San Diego uses an ANSI and The Climate Registry (TCR) accredited verification body to validate our emissions that are reported to TCR and the California Air Resources Board (CARB).
Documentation to support the GHG inventory verification process:

A brief description of how the institution accounted for its Scope 3 emissions:
Commuting emissions are calculated using survey data from Transportation Services/Commute Solutions. Business Air Travel emissions are calculated using the campus air miles traveled from Connexxus and the formula from AASHE and UNH SIMAP (formerly the Clean Air - Cool Planet Campus Carbon Calculator).
Has the institution completed an inventory within the previous three years to quantify its air pollutant emissions?:
Yes

Data source(s) and notes about the submission:
As noted previously, the gross square footage and physical boundary for UC San Diego's climate/greenhouse gas reporting includes our Hillcrest Medical Center, while the physical boundary and gross square footage for our other reporting do not. As a result, the GSF for GHG reporting does not match that used elsewhere in this report.
