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:
NC State uses SIMAP to complete its GHG emissions inventory and has used the tool since 2017. Partners from various areas of the university submit utility and fertilizer data to be entered by the Sustainability Office into SIMAP.

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:

Other sources --- ---

Total Scope 3 GHG emissions, performance year:
66,586.43 Metric tons of CO2 equivalent

A brief description of how the institution accounted for its Scope 3 emissions:
NC accounts for its Scope 3 emissions using SIMAP in areas like business travel and study abroad, commuting, paper purchasing, wastewater, landfilled waste, and transmission and distribution losses.

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) 44.39 Tons
Sulfur oxides (SOx) 2.40 Tons
Carbon monoxide (CO) 34.73 Tons
Particulate matter (PM) 1 Tons
Ozone (O3) 0 Tons
Lead (Pb) 0.30 Tons
Hazardous air pollutants (HAPs) 0 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 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:
We calculate emissions based on the best available information in the order that follows:

-Approved stack test data is used to calculate NOx emissions from the 3 combustion turbine generators and 3 heat recovery steam generators on campus.
-Approved continuous monitoring data is used to calculate NOx emissions from the two largest boilers.
-The manufacturer's certified emissions rates are used to calculate priority pollutant emissions from the emergency generators and fire pumps engines.
-EPA and/or State published emission factors. (For example, the EPA emission factors are used to calculate GHGs.)
