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:

2019_UCSD_TCR_Entity_Report_Submission.pdf

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).

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).

Part 2. Air pollutant emissions inventory

None

A brief description of the methodology(ies) the institution used to complete its air emissions inventory:

Local air district toxic emission inventory factors, source test data for some stationary sources and manufacturers’ emission factors when available.

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.
