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:
NMU hired an engineering consultant to create a campus energy master plan. As part of the plan, the consultant calculated a baseline greenhouse gas inventory for the campus. NMU provided hourly and monthly energy data including natural gas consumed, electricity purchased, gasoline and diesel fuel consumed by the university fleet. The data was provided for calendar years 2018 and 2019 because this period was prior to the COVID pandemic when campus operations were normal. During 2020 and 2021, university facilities operations were scaled back and did not reflect normal activities.
Impacts due to COVID prevented us from conducting a more recent (and accurate) assessment, thus we are using data from 2018-2019 and we have designated our performance year as 2018-2019. The consultant used the provided energy data and created a mass and energy balance to check that all energy conversions balanced. Then EIA for GHG emissions were applied to all to provide GHG emissions for each energy system, and finally
each energy system and its emissions were assigned to either Scope 1 for direct emissions or Scope 2 for indirect emissions.
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?:

| Hazardous air pollutants (HAPs) | 0 Tons |
| Ozone-depleting compounds (ODCs) | 0 Tons |
| Other standard categories of air emissions identified in permits and/or regulations | 1.35 Tons |
Do the air pollutant emissions figures provided include the following sources?:
| Yes or No | |
| Major stationary sources | Yes |
| Area sources | No |
| Mobile sources | No |
| Commuting | No |
| Off-site electricity production | No |
A brief description of the methodology(ies) the institution used to complete its air emissions inventory:
Michigan Air Emissions Reporting System (MAERS) is the State of Michigan's web-based application used in the collection of emission data from the permitted sources/facilities. The Michigan Department of Environment, Great Lakes and Energy (EGLE), Air Quality Division (AQD) maintains MAERS reports for commercial, industrial, and governmental sources of air pollution in Michigan.
NMU tracks our annual natural gas, wood, and fuel oil usage and applies those throughputs to a program of equations on the MAERS website. Based on our fuel usage quantities and on industry average fuel parameters, MAERS’ program calculates estimated emissions.
Note: Ozone, HAPs, ODCs are not part of our emission inventory. We entered "O" as a place holder for those pollutants.
Gross Scope 2 GHG emissions from purchased electricity (location-based):
Gross Scope 2 GHG emissions from imported thermal energy (location-based) :

Data source(s) and notes about the submission:
Impacts due to COVID prevented us from conducting a more recent (and accurate) assessment, thus we are using an older inventory and we have designated our performance year as 2018-2019.
