Scope 1 and Scope 2 GHG emissions

Gross GHG emissions

Gross Scope 1 and Scope 2 greenhouse gas (GHG) emissions:

	Performance year	Baseline year
Gross Scope 1 GHG emissions from stationary combustion	17.40 Metric tons of CO2 equivalent	27.20 Metric tons of CO2 equivalent
Gross Scope 1 GHG emissions from other sources	213 Metric tons of CO2 equivalent	213 Metric tons of CO2 equivalent
Gross Scope 2 GHG emissions from imported electricity	465.40 Metric tons of CO2 equivalent	541.52 Metric tons of CO2 equivalent
Gross Scope 2 GHG emissions from imported thermal energy	204 Metric tons of CO2 equivalent	258.70 Metric tons of CO2 equivalent
Total	899.80 Metric tons of CO2 equivalent	1,040.42 Metric tons of CO2 equivalent

Carbon sinks

Figures needed to determine net carbon sinks:

	Performance year	Baseline year
Third-party verified carbon offsets purchased	0 Metric tons of CO2 equivalent	0 Metric tons of CO2 equivalent
Institution-catalyzed carbon offsets generated	0 Metric tons of CO2 equivalent	0 Metric tons of CO2 equivalent
Carbon storage from on-site composting	0.45 Metric tons of CO2 equivalent	0 Metric tons of CO2 equivalent
Carbon storage from non-additional sequestration	0 Metric tons of CO2 equivalent	0 Metric tons of CO2 equivalent
Carbon sold or transferred	0 Metric tons of CO2 equivalent	0 Metric tons of CO2 equivalent
Net carbon sinks	0.45 Metric tons of CO2 equivalent	0 Metric tons of CO2 equivalent

If total performance year carbon sinks are greater than zero, provide:

A brief description of the carbon sinks, including vendor, project source, verification program and contract timeframes (as applicable):

We have two, small-scale composting systems on campus which collects plant-based food scraps from our student housing and dining hall. The compost is used to amend soils of the three campus gardens. We track the weight of food waste collected and weight of compost produced. We used these measurements and applied a conversion factor from the EPA's Waste Reduction Model (WARM) to calculate the metric tons of CO2e sequestered.

Adjusted net GHG emissions

Adjusted net Scope 1 and Scope 2 GHG emissions:

	Performance year	Baseline year
Adjusted net GHG emissions	899.35 Metric tons of CO2 equivalent	1,040.42 Metric tons of CO2 equivalent

Performance and baseline periods

Start and end dates of the performance year and baseline year (or three-year periods):

	Performance year	Baseline year
Start date	July 1, 2020	July 1, 2018
End date	June 30, 2021	June 30, 2019

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

Part 1. Reduction in GHG emissions per person

Weighted campus users

Figures needed to determine “Weighted Campus Users”:

	Performance year	Baseline year
Number of students resident on-site	68	100
Number of employees resident on-site	1	0
Number of other individuals resident on-site	0	0
Total full-time equivalent student enrollment	679	773
Full-time equivalent of employees	249.06	250
Full-time equivalent of students enrolled exclusively in distance education	463	430
Weighted Campus Users	366.04	469.75

Metrics used in scoring for Part 1

Adjusted net Scope 1 and 2 GHG emissions per weighted campus user:

	Performance year	Baseline year
Adjusted net Scope 1 and 2 GHG emissions per weighted campus user	2.46 Metric tons of CO2 equivalent	2.21 Metric tons of CO2 equivalent

Percentage reduction in adjusted net Scope 1 and Scope 2 GHG emissions per weighted campus user from baseline:

Part 2. GHG emissions per unit of floor area

Performance year floor area

Gross floor area of building space, performance year:

9,868.44 Gross square meters

Floor area of energy intensive building space, performance year:

	Floor area
Laboratory space	139.35 Square meters
Healthcare space	0 Square meters
Other energy intensive space	110.37 Square meters

EUI-adjusted floor area, performance year:

10,257.51 Gross square meters

Metric used in scoring for Part 2

Adjusted net Scope 1 and 2 GHG emissions per unit of EUI-adjusted floor area, performance year:

0.09 MtCO2e per square meter

A brief description of the institution’s GHG emissions reduction initiatives:

We are currently replacing as many fixtures as possible with low-emitting alternatives, prioritizing efforts on our oldest buildings first. We have also started a campus composting program to reduce our food waste footprint. In addition, the pandemic has encouraged more remote/online learning rather than having students commute to classes. However, we have not used a rigorous method to track any vehicle fleet emissions or commuting emissions by staff, students, and faculty. That being said, recent symposiums/conferences have also been exclusively virtual which has cut transportation emissions.

Data source(s) and notes about the submission:

"Number of students resident on-site" for the Baseline Year is an estimate.

Significant reductions in GHG emissions between Baseline and Performance years may have been impacted by the COVID pandemic (fewer on-campus activities, less on-campus residents, increase in remote work, etc.)
