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:

UW-Madison utilized the SIMAP (Sustainability Indicator Management and Analysis Platform) tool to complete the GHG emissions inventory (https://unhsimap.org/home). SIMAP offers campuses a simple, comprehensive, and affordable online tool for measuring, calculating, and reporting carbon and nitrogen footprints. The mission of SIMAP is to help institutions, colleges, and universities track their carbon and nitrogen footprints so they can meet their sustainability goals as effectively and efficiently as possible.


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:

One staff member from the Office of Sustainability reviewed the data used to populate the SIMAP tool to confirm completeness of data used. In addition, a staff member from the University of Wisconsin - Milwaukee reviewed the SIMAP tool to ensure the settings were appropriate for the region and our approach to GHG accounting.

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

Leveraging the emission factors and calculation methodologies included in SIMAP, UW-Madison included the following components in the Scope 3 Inventory:
- Business Travel: Estimates of emissions from air travel booked through UW-Madison's central travel agency (Fox World Travel / Travel Incorporated) and the travel agency used by the athletics department (Anthony Travel) were included. This is estimated to capture 90% of business air travel from students, staff, and faculty. Estimates of personal vehicle use for business travel (through tracked mileage reimbursement) were also included.
- Commuting: Emissions from student, staff, and faculty commuting were estimated from mode choice and distance traveled data obtained from the 2018 biennial transportation survey (most recent survey to address pre-pandemic travel trends).
- Purchased Goods and Services: Estimates of emissions from purchased paper products on campus were included.
- Waste Generated in Operations: Estimates of emissions from solid waste and wastewater generated from campus operations were included.
- Fuel- and energy-related activities not included in Scope 1 or Scope 2: SIMAP calculates emissions from transmission and distribution losses associated with electricity use.
- Other: Estimates of emissions from student study abroad air travel (based on study location) were included.

A brief description of the methodology(ies) the institution used to complete its air emissions inventory:

The data reported above is from the most recent inventory of emissions from campus stationary sources. The inventory was completed for 2020 as a result of three campus air emission permits executed by the Wisconsin Department of Natural Resources (DNR):
- UW Safety Management (FID# 113103430)
- UW Walnut St. Plant (FID# 113134230)
- UW Charter St. Plant (FID# 113008390)

(Historical data is available at the link provided in the "Optional" section below and each facility can be identified by FID#)

All data reported above are in Short Tons. The Charter St. Plant and UW Safety Management sources produced reportable emissions in 2020. The UW Safety Management permit covers emissions from area sources across the UW-Madison campus including incinerators and sterilizers. The "other" data reported includes 14.20 tons of PM10, 13.84 tons of PM2.5, 10.33 tons of Reactive Organic Gases (ROG), 0.57 tons of VOCs (from vehicle fuels) and 3.99 tons of Nitrousoxide.

Trace amounts (<0.01 tons) of the following were also included in emissions analysis: Arsenic; Barium; Benzene; Cadmium; Chromium Met; Cobalt; Copper Ethylene Oxi; Manganese; Mercury; Methane; Molybdenum; Naphthalene; Nickel CMP; Pentane; Toluene.

Emissions data was collected utilizing the Wisconsin DNR Air Reporting System. Details on the calculation methodology can be found here: https://dnr.wisconsin.gov/topic/AirEmissions/Tutorials.html

Emissions from mobile sources were calculated based upon fuel consumption for UW-Madison owned fleet vehicles and completed using the AFLEET tool (https://greet.es.anl.gov/afleet_tool).
