Performance year for scope 1 and 2 GHG emissions:
Description of the methodology or calculator used to conduct the scope 1 and 2 GHG emissions inventory:
Scope 1 emissions were calculated using annualized data stationary combustion data compiled by the Office of Energy Management to produce emissions reports of our boilers/use of natural gas and propane as required by the Illinois Environmental Protection Agency. Data on mobile combustion was collected from monthly data maintained by University Fleet. Scope 2 emissions were provided by the Office of Energy Management and annualized using monthly electricity usage from our provider, MidAmerican Energy.
The emissions inventory attached to this submission is from fiscal year 2023 which spans from July 2022 to June 2023.
We used the 2022 emissions factors published by the Sustainability Indicator Management and Analysis Platform (SIMAP) to convert measures of consumption to kilograms of CO2, CH4, and N2O. For CO2 in calendar year 2023, data on Illinois average emissions factor from the Environmental Protection Agency (EPA)’s eGRID resource released in 2025 is used. All emissions factors are reported as CO2e emissions in metric tons. CH4 and N2O emissions are converted to CO2e using IPCC standards.
Scope 1 GHG emissions
If claiming points for a scope 1 and scope 2 GHG inventory, the following information is required:
Scope 1 GHG emissions from mobile combustion:
Scope 1 GHG process emissions:
Scope 1 GHG fugitive emissions:
