GHG Report for University of Illinois at Chicago
Submitted on January 31, 2012; last updated on February 3, 2012
Summary StatisticsMaking fair comparisons between higher education institutions is always challenging due to the rich diversity of higher education. The unverified nature of the information in this database and unavailability of unbiased normalization metrics means such comparisons are even more difficult. Users should therefore approach direct institution to institution comparisons with caution and recognize that all comparisons between institutions are inherently biased.

|Gross emissions (Scopes 1 + 2 + 3)||342,347 metric tons of CO2e||12.7 metric tons of CO2e||23.4 metric tons of CO2e||0%|

Emissions Inventory Methodology and Boundaries
|Start date of the 12-month period covered in this report||July 1, 2009|
|Consolidation methodology used to determine organizational boundaries||Operational control approach|
If any institution-owned, leased, or operated buildings or other holdings that should fall within the organizational boundaries are omitted, briefly explain why.
Rockford and Peoria campuses, as the office focuses on the Chicago campus only (building numbers in the 600s and 700s). Those two campuses might be included in the future
|Emissions calculation tool used||Clean Air-Cool Planet|
Please describe why this tool was selected.
This tool is most commonly used by colleges and universities. It is also the tool we used previously.
Please describe the source(s) of the emissions coefficients used.
CA-CP Campus Carbon Calculator's default emissions coefficients
|Which version of IPCC's list of global warming potentials did you use?||Third Assessment Report|
|Who primarily conducted this emissions inventory?||Sustainability office staff|
Please describe the process of conducting the inventory.
The Office of Sustainability energy interns collected data collected from different departments at the University. The data was then put into the Campus Carbon Calculator. We also conducted a travel inventory to estimate the emissions from commuting to campus.
Please describe any emissions sources that were classified as de minimis and explain how a determination of the significance of these emissions was made.
Refrigerants were considered de minimis because the major source for campus cooling are two central cooling towers. The power plants do not utilize refrigerants. No emissions from agriculture as there are no farms on campus.
Please describe any data limitations related to this submission and any major assumptions made in response to these limitations.
In FY2010 our emissions appear to have increased. This is because we went from using a custom mix of sources for our purchased electricity to using a regional mix. The custom mix was much higher in the low-carbon nuclear power that is prevalent in northeastern Illinois. Until August 2009, we purchased electricity on the retail market from ComEd and used their Environmental Disclosure Report to create the custom profile. As of August 2009, the University of Illinois began to purchase on the wholesale market and through PPAs. We can no longer trace the source of electricity for those purchases so we feel the regional mix is the best choice. For Scope 3: Assumptions were made for commuting emissions. The proportion of survey respondents reporting in each category (faculty, staff, students) was assumed to be the same as the campus population as a whole and the percentages from the survey were used as campus percentages. We considered the Chicago Transit System to be "light rail" and the Metra Commuter system to be "heavy rail". This is not fully accurate. For Scope 1 emissions, we assumed an average power plant efficiency that is not calculated because the plant has many different types of boilers, engines, etc with different efficiencies depending on the use at any given time.
