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:

Annual_Sustainability_Report_FY_2018-2019.pdf

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

In order to create a single, consistent methodology for calculating and reporting GHG emissions for the University, emissions for Vanderbilt, including those years prior to 2009, were calculated utilizing the EPA’s scope and emissions factors for relevant stationary sources. Transportation emissions were calculated using the EPA MOVES model.

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:

Validated internally by faculty, staff, and students independent of the GHG accounting and reporting process. Report is reviewed and verified by Director of Vanderbilt’s Sustainability and Environmental Management Office, Chair of the Environmental Advisory Committee, Vice Chancellor for Administration, Chief of Staff for Vice Chancellor for Administration, Associate Vice Chancellor for Facilities and Chief Facilities Officer, Assistant Vice Chancellor for Plant Operations, Environmental Management Systems Coordinator, and Sustainability Outreach Coordinator.

Documentation to support the GHG inventory verification process:

Scope 1 GHG emissions

Gross Scope 1 GHG emissions, performance year:

	Weight in MTCO2e
Stationary combustion	69,297 Metric tons of CO2 equivalent
Other sources (mobile combustion, process emissions, fugitive emissions)	1,562 Metric tons of CO2 equivalent

Total gross Scope 1 GHG emissions, performance year:

70,859 Metric tons of CO2 equivalent

Scope 2 GHG emissions

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

	Weight in MTCO2e
Imported electricity	39,661 Metric tons of CO2 equivalent
Imported thermal energy	0 Metric tons of CO2 equivalent

Total gross Scope 2 GHG emissions, performance year:

39,661 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	9,919 Metric tons of CO2 equivalent
Commuting	Yes	35,528 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	Yes	2,394 Metric tons of CO2 equivalent
Other sources	No	0 Metric tons of CO2 equivalent

Total Scope 3 GHG emissions, performance year:

47,841 Metric tons of CO2 equivalent

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

Air travel emissions are calculated using recorded passenger air miles from the University booking system multiplied by the WRI Greenhouse Gas Protocol Emission Factor. Waste disposal emissions are calculated using weights of waste streams, multiplied by emissions factors from the EPA, ICLEI Recycling/Composting Protocol, and Turner, Williams, and Kemp (https://www.sciencedirect.com/science/article/pii/S0921344915301245). Q4 commuters were significantly lower than Q1-3 due to COVID-19 campus operations alterations.

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)	80.60 Tons
Sulfur oxides (SOx)	3.10 Tons
Carbon monoxide (CO)	77.80 Tons
Particulate matter (PM)	14.10 Tons
Ozone (O3)	0 Tons
Lead (Pb)	0 Tons
Hazardous air pollutants (HAPs)	0 Tons
Ozone-depleting compounds (ODCs)	0 Tons
Other standard categories of air emissions identified in permits and/or regulations	11.50 Tons

Do the air pollutant emissions figures provided include the following sources?:

	Yes or No
Major stationary sources	Yes
Area sources	Yes
Mobile sources	Yes
Commuting	No
Off-site electricity production	No

None

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

Vanderbilt keeps a daily log of its fuel use and energy production and utilizes EPA’s AP-42 emission factors to determine the institution’s annual air emissions. Vanderbilt’s power plant is regulated by a Title V Air Permit managed by Metro Nashville Public Health Department.
Mobile source emissions are calculated using the FLEET tool from Argonne National Lab using fuel data.
