GHG Report for University of Arkansas Main Campus
Submitted on May 3, 2010; last updated on May 3, 2010
Summary Statistics
Making 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) | 118,227 metric tons of CO2e | 9.1 metric tons of CO2e | 17.6 metric tons of CO2e | 0% |
| Gross emissions (Scopes 1 + 2 + 3) | 158,583 metric tons of CO2e | 12.3 metric tons of CO2e | 23.6 metric tons of CO2e | 0% |
| Net emissions | 158,583 metric tons of CO2e | 12.3 metric tons of CO2e | 23.6 metric tons of CO2e | N/A |
Emissions Inventory Methodology and Boundaries
| Start date of the 12-month period covered in this report | July 1, 2004 |
| 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.
None. |
|
| 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.
eGRID provides regional coefficients for purchased electricity, by regional electric reliability council (SPP, Southwest Power Pool for the University of Arkansas). Other coefficients are taken from CA-CP. |
|
| 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, fugitive refrigerant reports, solid waste reports, and fertilizer invoices. Results of a 2005 commuter study were extrapolated to 2003 enrollment and employment levels to estimate commuting energy use. |
|
|
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.
Results of a 2005 commuter study and of a 2008 analysis of commercial air travel were extrapolated to 2003 enrollment and employment levels to estimate commuting and commercial air energy use levels. |

Auditing and Verification
These 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 College of Arts and Sciences graduate Environmental Dynamics Program. |
