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

Does the institution’s GHG emissions inventory include all, some or none of its Scope 3 GHG emissions from the following categories?:
All, Some, or None
Business travel All
Commuting All
Purchased goods and services Some
Capital goods None
Waste generated in operations All
Fuel- and energy-related activities not included in Scope 1 or Scope 2 All
Other categories Some

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, including how the institution accounted for each category of Scope 3 emissions reported above:

A modified CA-CP calculator is used.


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 internal and/or external verification process:

The annual GHG inventory is third-party verified by Sightlines LLC.


Documentation to support the internal and/or external verification process:
---

Does the institution wish to pursue Part 2 and Part 3 of this credit? (reductions in Scope 1 and Scope 2 GHG emissions):
Yes
