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 2022 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:

49,337
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 Blacksburg Transit Company. Electricity Transportation and Distribution (T&D) loss was calculated based on the utility (Appalachian Power Co.) T&D loss percentage. 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 detail in the GHG Assessment Report.
