GHG Report for University of Arkansas Main Campus
Submitted on August 29, 2008; last updated on February 2, 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.
|Total||Per Full-Time Enrollment||Per 1000 Square Feet||% Offset|
|Gross emissions (Scopes 1 + 2)||125,192 metric tons of CO2e||8.4 metric tons of CO2e||16.5 metric tons of CO2e||0%|
|Gross emissions (Scopes 1 + 2 + 3)||169,103 metric tons of CO2e||11.3 metric tons of CO2e||22.3 metric tons of CO2e||0%|
|Net emissions||169,103 metric tons of CO2e||11.3 metric tons of CO2e||22.3 metric tons of CO2e||N/A|
Emissions Inventory Methodology and Boundaries
|Start date of the 12-month period covered in this report||July 1, 2006|
|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.
|Emissions calculation tool used||Clean Air-Cool Planet|
Please describe why this tool was selected.
The approach is widely used and understandable, and it allows valid benchmarking with peer institutions. It is the methodology used by consultants who assisted us.
Please describe the source(s) of the emissions coefficients used.
American Electric Power, the electricity provider, provided us with the emissions coefficient that represents the typical supply to customers in the State of Arkansas. Non-electric coefficients came directly from Clean Air Cool Planet v5.
|Which version of IPCC's list of global warming potentials did you use?||Third Assessment Report|
|Who primarily conducted this emissions inventory?||a team of faculty, students, sustainability staff, and consultants|
Please describe the process of conducting the inventory.
Comprehensive data collection included compilation and detailed analyses of utility bills (including fuel source data for our electricity provider), steam and chilled water uses, fleet fuel uses, air travel documents, commuting studies, fugitive refrigerant reports, solid waste reports, and fertilizer invoices.
Please describe any emissions sources that were classified as de minimis and explain how a determination of the significance of these emissions was made.
No information provided
Please describe any data limitations related to this submission and any major assumptions made in response to these limitations.
Detailed air travel data were analyzed for FY02 and extrapolated to FY06. Details describing fuel burning characteristcs and passenger loads of specific flights are not available for most flights, and we make assumptions based on typical aircraft and average passenger loads based on market sizes. We will collect and analyze start points and destination data for flights from FY03 through FY08 for the Sept 09 report.

Please describe any circumstances specific to your institution that provide context for understanding your greenhouse gas emissions this year.
Three-quarters of our emissions come from scope 2, coal-based, purchased electricity. The magnitude of our emissions is thereby defined largely by the high proportion of coal used by our electricity provider.

Auditing and VerificationThese emissions data have been audited, verified, or peer-reviewed.
Please briefly describe this verification, if any.
UA has contracted with Sightlines LLC to provide data and benchmarking for our energy use on campus through their Greenlines program. Through that agreement, Sightlines managers have provided professional peer review of our data integrity and analyses. Data sources, methods, and results have also been reviewed by the UA College of Engineering and the Environmental Dynamics Program.
