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 16,622.79 Metric tons of CO2 equivalent 15,791.07 Metric tons of CO2 equivalent
Gross Scope 1 GHG emissions from other sources 483 Metric tons of CO2 equivalent 577.40 Metric tons of CO2 equivalent
Gross Scope 2 GHG emissions from imported electricity 41,143.77 Metric tons of CO2 equivalent 52,476.71 Metric tons of CO2 equivalent
Gross Scope 2 GHG emissions from imported thermal energy 0 Metric tons of CO2 equivalent 0 Metric tons of CO2 equivalent
Total 58,249.56 Metric tons of CO2 equivalent 68,845.18 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 Metric tons of CO2 equivalent 0 Metric tons of CO2 equivalent
Carbon storage from non-additional sequestration 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 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):
While Facilities Management does do food and yard waste composting, the amount of carbon sequestered is unknown.

Adjusted net GHG emissions

Adjusted net Scope 1 and Scope 2 GHG emissions:
Performance year Baseline year
Adjusted net GHG emissions 58,249.56 Metric tons of CO2 equivalent 68,845.18 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, 2019 July 1, 2012
End date June 30, 2020 June 30, 2013

A brief description of when and why the GHG emissions baseline was adopted:
The period preceding 2013 included substantial growth in campus footprint and utility consumption. In the mid-2010s, UD had reached roughly its current building footprint, and utility usage was relatively stable on most of the campus, except for Curran Place which experienced rapid growth due to more intensive research labs that were being added to the facility. At the end of FY12-13, UD signed the ACUPCC. In the late 2010s, major energy efficiency efforts were under way. For this reason, 2013 is the most suitable baseline year.

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 6,382 6,126
Number of employees resident on-site 0 0
Number of other individuals resident on-site 0 0
Total full-time equivalent student enrollment 10,698 10,159
Full-time equivalent of employees 2,950 2,428
Full-time equivalent of students enrolled exclusively in distance education 566 386
Weighted Campus Users 11,407 10,682.25

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 5.11 Metric tons of CO2 equivalent 6.44 Metric tons of CO2 equivalent

Percentage reduction in adjusted net Scope 1 and Scope 2 GHG emissions per weighted campus user from baseline:
20.77

Part 2. GHG emissions per unit of floor area

Performance year floor area

Gross floor area of building space, performance year:
512,026.15 Gross square meters

Floor area of energy intensive building space, performance year:
Floor area
Laboratory space 108,711.84 Square meters
Healthcare space 0 Square meters
Other energy intensive space 0 Square meters

EUI-adjusted floor area, performance year:
729,449.83 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:
0.08 MtCO2e per square meter

A brief description of the institution’s GHG emissions reduction initiatives:
UD is a signatory of Second Nature and the We Are Still In commitment.

UD has a Green Revolving Fund that is used to fund energy efficiency projects on campus. It has been heavily utilized by energy management staff and has funded projects initiated outside of operations by faculty and student community members.

Data source(s) and notes about the submission:
Campus users differ in this section compared with PRE-5 because of differences in the reporting periods. PRE-5 demographic data is a snapshot of demographics from Fall 2020. GHG data is from the fiscal year reporting period July 2019 - June 2020.
