Part 1. Greenhouse gas emissions inventory
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:
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
| Weight in MTCO2e | |
| Stationary combustion | 69,461 Metric tons of CO2 equivalent |
| Other sources (mobile combustion, process emissions, fugitive emissions) | 967 Metric tons of CO2 equivalent |
Total gross Scope 1 GHG emissions, performance year:
70,428
Metric tons of CO2 equivalent
Scope 2 GHG emissions
| Weight in MTCO2e | |
| Imported electricity | 27,092 Metric tons of CO2 equivalent |
| Imported thermal energy | 0 Metric tons of CO2 equivalent |
Total gross Scope 2 GHG emissions, performance year:
27,092
Metric tons of CO2 equivalent
GHG emissions from biomass combustion
0
Metric tons of CO2 equivalent
Scope 3 GHG emissions
| Yes or No | Weight in MTCO2e | |
| Business travel | Yes | 421 Metric tons of CO2 equivalent |
| Commuting | Yes | 20,038 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 | 3,274 Metric tons of CO2 equivalent |
| Other sources | No | 0 Metric tons of CO2 equivalent |
Total Scope 3 GHG emissions, performance year:
23,733
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
Yes
Annual weight of emissions for::
| Weight of Emissions | |
| Nitrogen oxides (NOx) | 79.90 Tons |
| Sulfur oxides (SOx) | 5 Tons |
| Carbon monoxide (CO) | 76.30 Tons |
| Particulate matter (PM) | 14.20 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 | 10.60 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.
Mobile source emissions are calculated using the FLEET tool from Argonne National Lab using fuel data.
