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 FY19 and FY20 data.


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 and the Director of Duquesne's Sustainable MBA Program.
