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:
USU Facilities calculates the greenhouse gas inventory with the University of New Hampshire SIMAP calculator.

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?:
No

A brief description of the GHG inventory verification process:
---

Documentation to support the GHG inventory verification process:
---

Scope 1 GHG emissions
Gross Scope 1 GHG emissions, performance year:
Weight in MTCO2e
Stationary combustion 41,563.95 Metric tons of CO2 equivalent
Other sources (mobile combustion, process emissions, fugitive emissions) 5,757.83 Metric tons of CO2 equivalent

Total gross Scope 1 GHG emissions, performance year:
47,321.78 Metric tons of CO2 equivalent

Scope 2 GHG emissions
Gross Scope 2 GHG emissions, performance year (market-based):
Weight in MTCO2e
Imported electricity 11,972.13 Metric tons of CO2 equivalent
Imported thermal energy 0 Metric tons of CO2 equivalent

Total gross Scope 2 GHG emissions, performance year:
11,972.13 Metric tons of CO2 equivalent

GHG emissions from biomass combustion
Gross GHG emissions from biogenic sources, performance year:
0 Metric tons of CO2 equivalent

Scope 3 GHG emissions
Does the GHG emissions inventory include Scope 3 emissions from the following sources?:
Yes or No Weight in MTCO2e
Business travel Yes 567.85 Metric tons of CO2 equivalent
Commuting Yes 5,586.57 Metric tons of CO2 equivalent
Purchased goods and services Yes 17.72 Metric tons of CO2 equivalent
Capital goods No 0 Metric tons of CO2 equivalent
Fuel- and energy-related activities not included in Scope 1 or Scope 2 Yes 1,184.06 Metric tons of CO2 equivalent
Waste generated in operations Yes 2,483.41 Metric tons of CO2 equivalent
Other sources No 0 Metric tons of CO2 equivalent

Total Scope 3 GHG emissions, performance year:
9,839.61 Metric tons of CO2 equivalent

A brief description of how the institution accounted for its Scope 3 emissions:
Commuting is estimated from a survey of students, faculty, and staff. The results were used to calculate the means for days per week, miles per day, and MPG. We also formulated a percentage of persons driving, carpooling, bus, walking, biking, etc. This was all done with seasonal variability calculated. Estimates for commuting during COVID took into account the format of classes offered in the '20-'21 academic year.

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) 42.12 Metric tons
Sulfur oxides (SOx) 2.67 Metric tons
Carbon monoxide (CO) 13.40 Metric tons
Particulate matter (PM) 3.45 Metric tons
Ozone (O3) 0 Metric tons
Lead (Pb) 0 Metric tons
Hazardous air pollutants (HAPs) 0.60 Metric tons
Ozone-depleting compounds (ODCs) 0 Metric tons
Other standard categories of air emissions identified in permits and/or regulations 0 Metric tons

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

None
A brief description of the methodology(ies) the institution used to complete its air emissions inventory:
All calculations were based on mass balance, fuel consumption multiplied by emission values from EPA Air-CHIEF. Ozone, lead, and ODCs are not tracked.
