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:
A brief description of the methodology and/or tool used to complete the GHG emissions inventory:
Tennessee Tech uses UNH's Campus Carbon Calculator to track GHG emissions. This is an excel-based spreadsheet that has a category for each area of GHG emissions possible. Data was collected from many departments throughout campus to account for the numbers. The Office of Sustainability has many tracking documents that departments are able to update in order to be current in the information that is recorded on the tracking document. Each category was accounted for by Tennessee Tech's Business and Facilities Office and the Office of Sustainability. Included in the calculator is all scope 1 and 2 and partial scope 3 emissions. The data determines the amount of carbon emissions for every fiscal year.

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 inventory has been verified by the Sustainability Manager,DeLayne Miller, and by various other Facilities service managers. Many spreadsheets recording this data have been used and compared to ensure that the data is as accurate as possible.

A brief description of how the institution accounted for its Scope 3 emissions:
Tennessee Tech uses UNH's Campus Carbon Calculator to track GHG emissions. This is an excel-based spreadsheet that has a category for each area of GHG emissions possible. Data was collected from many departments throughout campus to account for the numbers. The Office of Sustainability has many tracking documents that departments are able to update in order to be current in the information that is recorded on the tracking document.

None
A brief description of the methodology(ies) the institution used to complete its air emissions inventory:
Air emissions are checked and reported monthly per requirements of our Title V permit (Clean Air Act). TN Tech contracts with Environmental Source Sampler, Inc. & PowerSecure, Inc. to provide the air emissions sampling results in report form.

Optional Fields
