A brief description of how the institution accounted for its Scope 3 emissions:
​​Georgia Tech uses different methods to evaluate the different categories of scope 3 emissions:

● ​Business Travel – GT tracks the emissions from flights booked through the campus travel system. Emission factors from EPA (categorizing into short, medium, and long haul) and a Radiative forcing factor of 2.7 are used in this category.

● ​Commuting - Commute data comes from an annual commute survey conducted by Parking and Transportation (PTS) Georgia Tech. The data is extrapolated based on campus FTE across staff, students, and faculty. EPA emission factors are used in this category.

● ​Fuel- and energy-related activities not included in Scope 1 or Scope 2 – Georgia Tech includes the upstream and downstream emissions related to Natural Gas and Electricity:

● ​Electricity T&D Losses – The transmission and Distribution Losses are set at 5.7% based on the EIA Annual Electric Power Industry Report for Georgia Power.

​ ● Natural Gas - Upstream leakage is taken from an EDF study which estimates a 2.2% leakage rate from production, distribution, and delivery. This upstream leakage accounts for all leakage before the natural gas reaches Georgia Tech campus. We Assume that the density of natural gas is 0.8 kg per cubic meter and that natural gas is 93.4% methane and 1% carbon dioxide.

​● Waste generated in operations – GT uses a improved methodology to better estimate waste emissions on a case by case basis. Waste emissions includes landfill emissions, compost emissions, and recycling transportation.

● ​Landfill emissions: Total landfill gas produced from Georgia Tech's landfilled waste was calculated using ICLEI's ClearPath tool. Net CH4 capture was calculated by taking the difference between total CH4 produced without landfill gas collection and under a scenario with "typical" landfill gas collection. The net methane capture is then converted to total scf of total landfill gas. Note that ClearPath assumes a typical LFG collection efficiency which may differ from the actual efficiency of the collection system.

● ​Recycling – Currently only includes the emissions associated with transportation of recycling waste. The avoided emissions from recycling base on the EPA WARM model are calculated as information only and not include in the inventory.

​ ● Composting – Emissions factors from EPA WARM model are used for this section.

● ​Other Sources – Study Abroad student travel is included in this category. information from the Georgia Tech 2022 Fact book was used to identify the top 10 study abroad countries and the number of students who traveled to each location. It was assumed that upon return, students would take the same route back to Atlanta. Distances were multiplied by two, for round trip distance, and by the total number of students who flew to each destination to get total passenger-miles traveled by flight length category. Emission calculation follows a similar methodology to Business Travel. ​
