Has the institution conducted a GHG emissions inventory within the previous three years that includes all Scope 1 and 2 emissions? :
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:
Scope 1 emissions from university-owned vehicles
Data for university-owned vehicles was collected using odometer readings for each vehicle in the year 2019 and early 2020. The difference between the readings is how miles driven was derived for each vehicle. Vehicles were segregated into fuel type, either gasoline or diesel to get total miles driven each fuel type.
Scope 1 mobile combustion emissions were calculated with the GHG Protocol’s calculation tool using the distance-based method with EPA’s 2018 emission factors. All vehicles fall under the ‘light-duty’ vehicle type which includes vans, pick-up trucks and SUV’s. The distance-based method was used because the university does not track fuel receipts or gallons for each vehicle, only odometer miles.
Scope 1 emissions data from natural gas
All data for years 2017-2019 was collected from Marquette University’s two natural gas service providers, WE Energies and Symmetry Energy for all commercial properties on campus. Exclusions include (1) buildings and spaces that are owned by Marquette University but leased out; and (2) 152 university apartments (residential classified accounts). Difficulty in obtaining the data from our service provider for these types of accounts was a challenge. The gross square feet for these properties is included in the submission.
Scope 2 emissions data from purchased electricity
All data for years 2017-2019 was collected from our electricity provider WE Energies for all commercial properties. Exclusions include buildings and spaces that are owned by Marquette but leased out and 128 university apartments.
Scope 2 emissions data from purchased steam
All data for years 2017-2019 was collected from our steam service provider WE Energies for all commercial properties.
Calculations
Electricity, district steam, and natural gas emissions were calculated using an Excel tool created by Noelle Brigham, Professor of Practice at the Opus College of Engineering at Marquette University. The tool uses the Environmental Protection Agency’s GHG emission factors for each source based on the year.
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?:
A brief description of the GHG inventory verification process:
The inventory was sent to a colleague at the University of Wisconsin-Milwaukee to review and verify the inventory.
Documentation to support the GHG inventory verification process:

| Weight in MTCO2e | |
| Stationary combustion | 4,954 Metric tons of CO2 equivalent |
| Other sources (mobile combustion, process emissions, fugitive emissions) | 212.16 Metric tons of CO2 equivalent |
Total gross Scope 1 GHG emissions, performance year:
Gross Scope 2 GHG emissions, performance year (market-based):
| Weight in MTCO2e | |
| Imported electricity | 36,257 Metric tons of CO2 equivalent |
| Imported thermal energy | 16,441 Metric tons of CO2 equivalent |
