Has the institution conducted a GHG emissions inventory that includes all Scope 1 and 2 emissions? :
Yes

Does the institution’s GHG emissions inventory include all, some or none of its Scope 3 GHG emissions from the following categories?:
All, Some, or None
Business travel None
Commuting None
Purchased goods and services None
Capital goods None
Waste generated in operations None
Fuel- and energy-related activities not included in Scope 1 or Scope 2 None
Other categories None

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, including how the institution accounted for each category of Scope 3 emissions reported above:

Scope 1 emissions include:
- coal burned in the steam & electricity cogeneration plant
* coal mass is metered as it enters the boiler
* high heating value is measured daily by an offsite lab
- natural gas metered use
- propane purchased
- diesel fuel purchased for stationary generators
- fleet fuel metered use on and off campus
* gasoline (E10), ethanol (E85), and diesel
- Calculations include
* USEPA GHG emission factors for CO2, CH4, N2O
* 100-year GWP data from IPCC AR5 for CH4 & N2O equivalent CO2 emissions
Scope 1 emissions do not include:
- refrigerants. SIUC does not systematically track refrigerants for reporting purposes. Purchases are tracked for accounting purposes and a use tracking system based on this data is still in development.
- direct purchases of motor fuels for farm use. Most farms motor fuel is purchased from Travel Services and is counted. However, a small amount of fuel is purchased directly by farms. We are still working to properly track this fuel.
Scope 2 emissions include:
- off-site emissions from generating purchased electricity
* Emissions disclosures by fiscal year and supplier were obtained from the Illinois Commerce Commission for energy delivered by the investor-owned utility, Ameren.
* For energy supplied by electric cooperatives, output and emissions were found by year for the specific generation plants using the USEPA eGRID database.
Scope 2 electricity emissions do not include:
- GHG emissions from CH4 and N2O as these data are not available
- transmission and distribution losses between the generator and delivery point
See the attached inventory spreadsheet for all calculations, data sources, and assumptions used.
No Scope 3 emissions were estimated.


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 internal and/or external verification process:

An external review of the GHG emissions inventory was completed by Asia Abobaker, Energy Efficiency Professional and certified LEED Green Associate. Asia completed the independent review of the credit, utilizing the attached STARS document, as well as feedback over email. Asia’s comments on the document, as well as email, were reviewed by the STARS GHG lead before final submission. The questions and responses from this email interaction have been copied and pasted into the attached document. Asia is a Masters graduate from the Mechanical Engineering and Energy Processes, SIU. Contact information is included on the attached document.


Documentation to support the internal and/or external verification process:
Does the institution wish to pursue Part 2 and Part 3 of this credit? (reductions in Scope 1 and Scope 2 GHG emissions):
Yes

A brief description of the institution’s GHG emissions reduction initiatives, including efforts made during the previous three years:

The most significant factors in reducing our GHG emissions over time are:
- decreased use of coal in favor of natural gas, nuclear, and wind power in our electricity supply
- decreased use of coal in favor of natural gas in our cogeneration plant since 2013.
- energy efficiency projects including conversion to LED lighting and retrocommissioning of HVAC controls across campus
