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:

Vassar utilizes the SIMAP Platform run by the UNH Sustainability Institute.

Scope 1 and 2 data is compiled by Facilities Operations from utility bills.

For Scope 3:
Commuting emissions were calculated based on a comprehensive mode share survey with a ~60% response rate.
Business travel and student study abroad travel emissions are calculated by establishing a dollar-per-mile conversion through reviewing college credit card reports and running an airplane miles calculation based on the coordinates of Vassar and the destination. This conversion is updated every 3 years; in intervening years, a more expedited conversion of total spending times the conversion factor is undertaken.
Remaining data is tracked through reports provided by our vendors.


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:

The Sustainability Office leads the regular updating of the college's Greenhouse Gas emissions inventory. Once the calculator has been updated, faculty and administrators from the Sustainability Committee volunteer to provide an independent review of the numbers.
