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:

SU_GHG_Inventory.xlsx

A brief description of the methodology and/or tool used to complete the GHG emissions inventory:

Scope 1 Stationary Sources - Southwestern University only uses natural gas. Consumption data were collected using billing information. Calculations were done using EPA Emissions Factors.

Scope 1 Mobile - Records of the total gallons of gasoline purchased are not kept. To calculate, we took the total cost of gasoline purchased in a given month and divided it by the average cost of fuel in Texas during that month. Calculations were done using EPA Emissions Factors.

Scope 1 Refrigerant - Total annual amount of refrigerant purchased per type was provided by the Facilities Management team. Calculations were done using their respective Global Warming Potential.

Scope 1 Fertilizer - Total annual amount of fertilizer purchased per type was provided by the Facilities Management team. Calculations were done using % N and EPA Emissions Factors.

Scope 2 Purchased Electricity - Consumption data were collected using billing information. Calculations were done using EPA's eGrid Emissions Factors. Southwestern University purchases RECs to cover 100% of its electricity usage.

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 was verified and reviewed by the Sustainability Committee.
