"---" indicates that no data was submitted for this field

Does the institution's GHG emissions inventory include all Scope 1 and Scope 2 GHG emissions?:
Yes

Does the institution's GHG emissions inventory include all Scope 3 GHG emissions from any of the following categories?:
Yes or No
Business travel Yes
Commuting Yes
Purchased goods and services No
Capital goods No
Fuel- and energy-related activities not included in Scope 1 or Scope 2 No
Waste generated in operations Yes

Does the institution's GHG emissions inventory include Scope 3 emissions from other categories?:
No

A brief description of the methodology and/or tool used to complete the GHG emissions inventory:

The GHG emissions inventory was completed using data collected from all relevant college operating departments. The calculations were conducted using 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 internal and/or external verification process:

The report has been validated internally by senior staff and the campus environmental advisory committee.

Scope 1 GHG emissions from stationary combustion 13,315 Metric tons of CO2 equivalent 13,382 Metric tons of CO2 equivalent
Scope 1 GHG emissions from other sources 405 Metric tons of CO2 equivalent 576 Metric tons of CO2 equivalent
Scope 2 GHG emissions from purchased electricity 13,537 Metric tons of CO2 equivalent 9,585 Metric tons of CO2 equivalent
Scope 2 GHG emissions from other sources 0 Metric tons of CO2 equivalent 0 Metric tons of CO2 equivalent

Figures needed to determine “Weighted Campus Users”::
Performance Year Baseline Year
Number of residential students 1,973 1,925
Number of residential employees 136 124
Number of in-patient hospital beds 0 0
Full-time equivalent enrollment 2,079 2,056
Full-time equivalent of employees 1,064 818
Full-time equivalent of distance education students 0 0

Start and end dates of the performance year and baseline year (or three-year periods):
Start Date End Date
Performance Year July 1, 2013 June 30, 2014
Baseline Year July 1, 1990 June 30, 1991

A brief description of when and why the GHG emissions baseline was adopted:

We adopted 1991 as our baseline because that's the earliest year that we have comprehensive records.
