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:

2023_e-GGRT_GHG_Report_UI_PP_1.pdf

A brief description of the methodology and/or tool used to complete the GHG emissions inventory:

The inventory is conducted by EPA reporting standards - EPA Greenhouse Gas Reporting Program (GHGRP) using EPA's electronic Greenhouse Gas Reporting Tool (e-GGRT). The attached file is the data reported to the EPA in 2023.

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?:

Yes

A brief description of the GHG inventory verification process:

Scope 1 emissions are accounted for by EPA standards and Scope 2 are verified by University billing. Imported electricity converted to MTCO2e using EPA's Center for Corporate Climate Ledership, Scope 2 Emissions from Puchase Electricity GHG Caluclator Tool. Documentation for purchased electricity attached.

Scope 1 GHG emissions

Gross Scope 1 GHG emissions, performance year:

	Weight in MTCO2e
Stationary combustion	148,015.80 Metric tons of CO2 equivalent
Other sources (mobile combustion, process emissions, fugitive emissions)	0 Metric tons of CO2 equivalent

Total gross Scope 1 GHG emissions, performance year:

Scope 2 GHG emissions

Gross Scope 2 GHG emissions, performance year (market-based):

	Weight in MTCO2e
Imported electricity	85,261.40 Metric tons of CO2 equivalent
Imported thermal energy	0 Metric tons of CO2 equivalent

Total gross Scope 2 GHG emissions, performance year:

85,261.40 Metric tons of CO2 equivalent

GHG emissions from biomass combustion

Gross GHG emissions from biogenic sources, performance year:

21,191.50 Metric tons of CO2 equivalent

	Yes or No	Weight in MTCO2e
Business travel	---	---
Commuting	---	---
Purchased goods and services	---	---
Capital goods	---	---
Fuel- and energy-related activities not included in Scope 1 or Scope 2	---	---

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)	172.39 Tons
Sulfur oxides (SOx)	55.96 Tons
Carbon monoxide (CO)	125.70 Tons
Particulate matter (PM)	53.74 Tons
Ozone (O3)	0 Tons
Lead (Pb)	0.01 Tons
Hazardous air pollutants (HAPs)	12.14 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	No
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:

Emisions calulations use a standardized process to report actual facility wide emissions for each calendar year, as required by the Iowa Department of Natural Resources (IDNR). The unviersity records monthly, calculates the annual calendar year throughput, and multiplies each total by an IDNR accepted emission factor (EF) that is derived from emission point specific testing, manufacturer's data, AP-42, or other determination.

Optional Fields

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:

As the university shifts away from coal as the primary fuel in the power plant, reportable air emissions from the power plant are decreasing. Comparing emissions from the years 2020 and 2023 show significant decreases in criteria pollutant emissions including SO2, NOx, VOC, CO, PM, PM10, and PM 2.5. Reportable emissions in 2023 were almost 300 tons less than reported emissions in 2020.
