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:

2021_Luther_College_Carbon_Footprint_From_SIMAP.xlsx

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

The University of New Hampshire's Sustainability Institutes SIMAP tool was used to calculate emissions. We used the default emissions coefficients provided by this tool in our calculations. There are supporting documents for each of the categories directly paid by Luther College. These expenses are reconciled to the College's audited financial statements. The units associated with carbon amounts were collected from these detailed expenditures and totaled for each carbon category. The emissions resulting from rented property for the Nurses in Rochester, MN and in Nottingham, England represent less than .3 of 1% of the total college owned properties, and it would not be practical to obtain these emissions as the utilities figures are not provided or paid by Luther, so these sources were left out.

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?:

Scope 1 GHG emissions

Gross Scope 1 GHG emissions, performance year:

	Weight in MTCO2e
Stationary combustion	5,329.50 Metric tons of CO2 equivalent
Other sources (mobile combustion, process emissions, fugitive emissions)	160.73 Metric tons of CO2 equivalent

Total gross Scope 1 GHG emissions, performance year:

5,490.23 Metric tons of CO2 equivalent

Scope 2 GHG emissions

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

	Weight in MTCO2e
Imported electricity	3,413.80 Metric tons of CO2 equivalent
Imported thermal energy	0 Metric tons of CO2 equivalent

Total gross Scope 2 GHG emissions, performance year:

3,413.80 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	40.10 Metric tons of CO2 equivalent
Commuting	Yes	443.73 Metric tons of CO2 equivalent
Purchased goods and services	No	0 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	309.84 Metric tons of CO2 equivalent
Waste generated in operations	Yes	385 Metric tons of CO2 equivalent
Other sources	Yes	12.64 Metric tons of CO2 equivalent

Total Scope 3 GHG emissions, performance year:

1,191.31 Metric tons of CO2 equivalent

A brief description of how the institution accounted for its Scope 3 emissions:

Luther College tracks our air travel used for business purposes, as well as our landfilled waste, wastewater treatment, and calculates commuting. The 12.64 MT of "Other sources" is from wastewater treatment.

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)	2.58 Tons
Sulfur oxides (SOx)	0.02 Tons
Carbon monoxide (CO)	3.72 Tons
Particulate matter (PM)	0.34 Tons
Ozone (O3)	---
Lead (Pb)	---
Hazardous air pollutants (HAPs)	---
Ozone-depleting compounds (ODCs)	---
Other standard categories of air emissions identified in permits and/or regulations	---

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:

We input our boiler operational information in the State of Iowa State and Local Emissions Inventory System (SLEIS) and use the information derived from that system to report.

Optional Fields

Gross Scope 2 GHG emissions from purchased electricity (location-based):

6,229 Metric tons of CO2 equivalent
