6.1 Greenhouse gas emissions inventory and disclosure

Scope 1 and 2 GHG emissions inventory
Has the institution completed an inventory within the previous three years to quantify its scope 1 and scope 2 GHG emissions?:
Yes

Copy of the institution’s GHG emissions inventory:
---

Online location of the institution’s GHG emissions inventory:
https://unhsimap.org/public/institution/775

Performance year for scope 1 and 2 GHG emissions:
2022

Description of the methodology or calculator used to conduct the scope 1 and 2 GHG emissions inventory:
All emissions data are entered into SIMAP for calculation and reporting.
For on-campus combustion, emissions are measured on site by a third party. Because SIMAP is designed to accept a fuel input for combustion, combustion emissions must be entered into "Refrigerants and Chemicals" for accurate calculations.
For all other emissions categories including purchased electricity, fleet, fertilizer, refrigerants, travel, and purchases, the consumption data are entered into SIMAP which calculates the associated emissions in carbon dioxide equivalent. The calculator's default emission factors are used for Scope 3 calculations. A custom emission factor is used for purchased electricity calculations.

Scope 1 GHG emissions

If claiming points for a scope 1 and scope 2 GHG inventory, the following information is required:

---

If any scope 3 activities have been quantified, the following field is also required:

Description of the methodologies used to identify and account for the institution’s relevant scope 3 activities:

The University uses the Operational Control Approach for carbon accounting which means that the scope of emissions accounting includes what the University can control
