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:
A VT GHG Emissions Assessment Report is attached. The Sustainability Indicator Management and Analysis Platform (SIMAP) was used for the GHG Assessment. The assessment considers the VT main campus in Blacksburg primarily using 2019 calendar year data, all Scope 1 and 2 sources, and some Scope 3 sources as detailed in the VT GHG Emissions report.
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:
The GHG inventory has been quality checked several times by a number of VT faculty, students, and staff. It has also been 3rd-party verified by SIMAP and revised based on their recommendations.
Documentation to support the GHG inventory verification process:
Scope 1 GHG emissions
| Weight in MTCO2e | |
| Stationary combustion | 78,332 Metric tons of CO2 equivalent |
| Other sources (mobile combustion, process emissions, fugitive emissions) | 17,010 Metric tons of CO2 equivalent |
Total gross Scope 1 GHG emissions, performance year:
95,342
Metric tons of CO2 equivalent
Scope 2 GHG emissions
| Weight in MTCO2e | |
| Imported electricity | 124,166 Metric tons of CO2 equivalent |
| Imported thermal energy | 0 Metric tons of CO2 equivalent |
Total gross Scope 2 GHG emissions, performance year:
124,166

| Business travel | Yes | 9,184 Metric tons of CO2 equivalent |
| Commuting | Yes | 20,849 Metric tons of CO2 equivalent |
| Purchased goods and services | No | --- |
| Capital goods | No | --- |
| Fuel- and energy-related activities not included in Scope 1 or Scope 2 | Yes | 31,173 Metric tons of CO2 equivalent |
| Waste generated in operations | Yes | 67 Metric tons of CO2 equivalent |
| Other sources | No | --- |
Total Scope 3 GHG emissions, performance year:
61,273
Metric tons of CO2 equivalent
A brief description of how the institution accounted for its Scope 3 emissions:
Car commuting was estimated from parking permits and a campus commuter survey. Bus commuting was estimated based on direct fuel usage from the transit company. Electricity Transmission & Distribution (T&D) losses were calculated based on the utility (Appalachian Power Co) T&D loss percentage from 2016, the most recent year with published data. Upstream methane leakage from direct and indirect natural gas usage was estimated based on leakage rates from several recent scientific articles. Air travel emissions estimates were based on passenger-miles data from VT travel agencies and EPA airline emissions factors. Wastewater water and solid waste amounts were compiled and emissions estimated by SIMAP using default emissions factors. All of these methodologies and calculations are provided in more detailed in the GHG Assessment report.
Part 2. Air pollutant emissions inventory

| Ozone (O3) | --- |
| Lead (Pb) | 0 Tons |
| Hazardous air pollutants (HAPs) | 1.13 Tons |
| Ozone-depleting compounds (ODCs) | --- |
| Other standard categories of air emissions identified in permits and/or regulations | 3.53 Tons |

None
A brief description of the methodology(ies) the institution used to complete its air emissions inventory:
We use EPA AP-42 emission factors and total fuels used as specified by the Virginia Department of Environmental Quality.
