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:
SIMAP is used as the emissions calculator. Annual institutional data is collected for electricity, natural gas, fleet fuels, landfilled waste, and composting. Airmiles and commuter patterns are modeled from detailed studies on a subset of years with extrapolation in interim years.

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:
Baseline year is 2002-2003 and Performance year is 2021-2022. Scope 1 data includes natural gas and #2 oil purchased and used for onsite heating plants, and liquid fuels used in fleet vehicles. Scope 2 is entirely based on purchased electricity records.

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

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) 14.78 Tons
Sulfur oxides (SOx) 0.88 Tons
Carbon monoxide (CO) 12.47 Tons
Particulate matter (PM) 1.56 Tons
Ozone (O3) ---
Lead (Pb) 0.00 Tons
Hazardous air pollutants (HAPs) 0.30 Tons
Ozone-depleting compounds (ODCs) ---
Other standard categories of air emissions identified in permits and/or regulations 2.55 Tons

Do the air pollutant emissions figures provided include the following sources?:
Yes or No
Major stationary sources No
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:
Air emissions inventories are submitted for the air quality permit required by Mecklenburg County. The 2021 report lists 66 stationary diesel electricity generators, 90 natural gas boilers, a woodworking facility, and fuel storage. Pollutants include NOx, TSP, PM,-10, PM-2.5, TOC, NMTOC, CO and SOx. Hazardous air pollutants are reported for 35 categories, with emissions dominated by hexane, formaldehyde, toluene, trimethylpentane, and xylene; the most abundant heavy metals are nickel and lead.
