Gross Scope 1 and Scope 2 greenhouse gas (GHG) emissions:
| Performance year | Baseline year | |
| Gross Scope 1 GHG emissions from stationary combustion | 30,951.58 Metric tons of CO2 equivalent | 30,548.98 Metric tons of CO2 equivalent |
| Gross Scope 1 GHG emissions from other sources | 108.47 Metric tons of CO2 equivalent | 87.26 Metric tons of CO2 equivalent |
| Gross Scope 2 GHG emissions from imported electricity | 0 Metric tons of CO2 equivalent | 11,841.54 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 | 31,060.05 Metric tons of CO2 equivalent | 42,477.78 Metric tons of CO2 equivalent |
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 |
A brief description of the carbon sinks, including vendor, project source, verification program and contract timeframes (as applicable):
Duquesne University partners with a Agrecycle, Pennsylvania’s largest composting company. As a result, food waste from the dining halls is collected and composted via this third party. For FY21, 171.89 tons of Duquesne's food waste was composted. However, information regarding MT of eCO2 is not available.
Adjusted net Scope 1 and Scope 2 GHG emissions:
| Performance year | Baseline year | |
| Adjusted net GHG emissions | 31,060.05 Metric tons of CO2 equivalent | 42,477.78 Metric tons of CO2 equivalent |
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, 2013 |
| End date | June 30, 2021 | June 30, 2014 |
A brief description of when and why the GHG emissions baseline was adopted:
Duquesne Univesity chose fiscal year 2014 as our baseline year as that was the most accurate recording of University greenhouse gas emissions.
Figures needed to determine “Weighted Campus Users”:
| Performance year | Baseline year | |
| Number of students resident on-site | 3,068 | 3,822 |
| Number of employees resident on-site | 12 | 17 |
| Number of other individuals resident on-site | 2 | 0 |
| Total full-time equivalent student enrollment | 7,818 | 9,502 |
| Full-time equivalent of employees | 1,818 | 2,238 |
| Full-time equivalent of students enrolled exclusively in distance education | 749 | 310 |
| Weighted Campus Users | 7,437.25 | 9,532.25 |
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 | 4.18 Metric tons of CO2 equivalent | 4.46 Metric tons of CO2 equivalent |
Percentage reduction in adjusted net Scope 1 and Scope 2 GHG emissions per weighted campus user from baseline:
Gross floor area of building space, performance year:
Floor area of energy intensive building space, performance year:
| Floor area | |
| Laboratory space | 66,995 Square feet |
| Healthcare space | 4,253 Square feet |
| Other energy intensive space | 65,521 Square feet |
EUI-adjusted floor area, performance year:
Adjusted net Scope 1 and 2 GHG emissions per unit of EUI-adjusted floor area, performance year:
A brief description of the institution’s GHG emissions reduction initiatives:
Duquesne University has been purchasing RECs for many years, and in 2020, the school renewed its Power Purchase Agreement with Direct Energy Business, LLC. The new contract, which supports 66,362 MWh of any national Green-e Energy certified REC, extends over 4 years resulting in a yearly offset of approximately 16,590.5 MWh. As a result, the amount of RECs purchased reduces Scope 2 emissions significantly, sometimes even to zero.
