Part 1. Greenhouse gas emissions inventory

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:
Duquesne University's Center for Environmental Research and Education used the University of New Hampshire's carbon and nitrogen reporting tool, SIMAP, to complete the most recent Greenhouse Gas Report. This report includes FY22 data calculated using the 2022 emissions factors, which were released by SIMAP in February 2023.

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:
Data for all Scopes are analyzed using the Sustainability Indicator Management & Analysis Platform. Scope 1 and Scope 2 information is obtained from Facilities Management and Public Safety, and all commuting methods are determined based on a 2018 University Parking Memorandum. The number of students, faculty, and staff that commute are determined based on institutional data. Faculty and staff directly financed travel is obtained from the Purchasing Office. Air and bus travel for athletics is obtained from the Duquesne University Athletics website and mileage is calculated based on scheduled destinations. Waste generated is from Facilities Management. Receiving & Inventory and the Print Shop are contacted for paper usage. Offsets (composting) is provided via Facilities Management. The report is verified by CERE faculty members Dr. John Stolz and Dr. David Kahler. Additionally, the report is reviewed by members of Facilities Management, the Director of Duquesne's One-Year MBA Program (formerly the MBA in Sustainable Business Practices Program), and members of the University Sustainability Committee.

Yes or No Weight in MTCO2e
Business travel Yes 2,567.28 Metric tons of CO2 equivalent
Commuting Yes 8,845.10 Metric tons of CO2 equivalent

A brief description of how the institution accounted for its Scope 3 emissions:
All information regarding commuting was obtained from the 2018 Duquesne University Parking, Traffic and Transportation Demand Management Strategies Technical Memorandum #2, and institutional data was received from the Office of Institutional Research and Planning. Business travel expenses were provided by the Office of Procurement and Payment Services. Total T&D losses were automatically generated by SIMAP.

Part 2. Air pollutant emissions inventory

Has the institution completed an inventory within the previous three years to quantify its air pollutant emissions?:
Yes

Annual weight of emissions for::
Weight of Emissions
Nitrogen oxides (NOx) 22.24 Tons
Sulfur oxides (SOx) 0.82 Tons
Carbon monoxide (CO) 16.07 Tons
Particulate matter (PM) 0.90 Tons
Ozone (O3) 0 Tons
Lead (Pb) 0.00 Tons
Hazardous air pollutants (HAPs) 0.33 Tons
Ozone-depleting compounds (ODCs) 0 Tons
Other standard categories of air emissions identified in permits and/or regulations 0 Tons

Do the air pollutant emissions figures provided include the following sources?:
Yes or No
Major stationary sources Yes
Area sources ---
Mobile sources ---
Commuting ---
Off-site electricity production ---

None
A brief description of the methodology(ies) the institution used to complete its air emissions inventory:
In 2020, Duquesne's cogeneration plant was sold to Cordia (formerly Clearway Energy). Therefore, Duquesne's air pollutant emissions have dropped below the reporting requirement, making this report no longer accessible to Duquesne's Health and Safety team. This air emissions inventory was conducted by Cordia in accordance with the Allegheny County Health Department - Air Quality Program. The inventory includes the campuses main generators, turbines, cooling tower, and boilers. Data reported in this section are from the 2021 air pollutant emissions inventory.

Optional Fields

Gross Scope 2 GHG emissions from purchased electricity (location-based):
8,410.69 Metric tons of CO2 equivalent

Gross Scope 2 GHG emissions from imported thermal energy (location-based) :
0 Metric tons of CO2 equivalent

Data source(s) and notes about the submission:
In regards to our uploaded GHG emissions inventory: Market-based approach to reporting means that emissions from Scope 2 purchased electricity are offset with our purchase of renewable energy credits and so are reduced from the actual amount purchased.
