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:

Second_Nature_2020.csv

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

The university uses the SIMAP tool for calculating emissions inventories. The inventory includes Scope 1 and 2 emissions and Scope 3 commuting and air travel. Input data is gathered by the Office of Sustainability annually from data custodians across the institution and then enters that information into SIMAP. We follow an operational control approach from the GHG Protocol (https://ghgprotocol.org/).

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	172,116 Metric tons of CO2 equivalent
Other sources (mobile combustion, process emissions, fugitive emissions)	7,271 Metric tons of CO2 equivalent

Total gross Scope 1 GHG emissions, performance year:

179,387 Metric tons of CO2 equivalent

Scope 2 GHG emissions

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

	Weight in MTCO2e
Imported electricity	45,903 Metric tons of CO2 equivalent
Imported thermal energy	0 Metric tons of CO2 equivalent

Total gross Scope 2 GHG emissions, performance year:

45,903 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	36,862 Metric tons of CO2 equivalent
Commuting	Yes	50,032 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	No	0 Metric tons of CO2 equivalent
Waste generated in operations	No	0 Metric tons of CO2 equivalent
Other sources	No	0 Metric tons of CO2 equivalent

Total Scope 3 GHG emissions, performance year:

86,894 Metric tons of CO2 equivalent

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

We use air travel spend data provided by the University's Purchasing Department. That spend data is entered directly into SIMAP which calculates emissions associated with travel based on estimated emissions per $ of travel spend. For commuting, we obtain anonymized address data and use ArcGIS to calculate average travel distances from residence to campus. Bus pass sales data and distance traveled are used to develop estimated mode share split. This combined with assumptions on assumed trip frequency is entered into SIMAP to calculate estimated emissions attributable to commuting.

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)	79.60 Tons
Sulfur oxides (SOx)	5.50 Tons
Carbon monoxide (CO)	79.90 Tons
Particulate matter (PM)	6.37 Tons
Ozone (O3)	---
Lead (Pb)	0.00 Tons
Hazardous air pollutants (HAPs)	10.30 Tons
Ozone-depleting compounds (ODCs)	0 Tons
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	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:

The University of Minnesota submits an annual air emissions inventory to the Minnesota Pollution Control Agency as required by the Title V air permit issued to the Facility. Emissions are calculated using a combination of Continuous Emissions Monitoring System (CEMS) data, fuel throughput quantities, Performance Test data, and published emissions factors (EPA - AP 42/Webfire).
