GHG Report for Austin College
Submitted on January 6, 2012; last updated on January 6, 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)||9,582 metric tons of CO2e||6.9 metric tons of CO2e||12.4 metric tons of CO2e||14%|
|Gross emissions (Scopes 1 + 2 + 3)||13,599 metric tons of CO2e||9.9 metric tons of CO2e||17.5 metric tons of CO2e||10%|
|Net emissions||12,246 metric tons of CO2e||8.9 metric tons of CO2e||15.8 metric tons of CO2e||N/A|
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.
The college rents a few small houses that are remote from campus. The college does not pay the utilities for those houses. Those houses are not included in this report. Other college-owned houses that are residences of administrators are included in this report. All 14 campus electricity accounts are included in this report, plus the electricity consumption for the house at the McCarley Reserve and the Pavilion at the Sneed Prairie Restoration.
|Emissions calculation tool used||Clean Air-Cool Planet|
Please describe why this tool was selected.
This is the calculator recommended by the ACUPCC. Because it is widely used its use facilitates comparison with other campuses. An earlier version of this calculator was used for the College’s fiscal year 2008 inventory; using the up-to-date version of the same calculator facilitates comparison of Austin College emissions data from year to year. We used CACP version 6.6 for this inventory.
Please describe the source(s) of the emissions coefficients used.
As per the protocol used for Austin College’s fiscal year 2008 inventory, default coefficients were used with the following exceptions. We changed the Radiation Forcing Index from 2.8 to 2 because various IPCC reports have used different values and our local expert, Dr. David Baker, does not think the relevant science warrants specifying this value to two significant figures. We corrected the CO2 emissions of study abroad flights by a factor of 0.64 to reflect their longer distances and thus better fuel efficiency than the shorter domestic flights that the calculator assumes. We used actual community data for commuting distances, vehicles used, and carpooling based on a detailed survey.
|Which version of IPCC's list of global warming potentials did you use?||Third Assessment Report|
|Who primarily conducted this emissions inventory?||Student researcher(s)|
Please describe the process of conducting the inventory.
The inventory was completed by senior honors thesis student Katie Masucci, a member of the Austin College Class of 2011, under the direction of her thesis committee [Peter Schulze (chair)]. Peter Schulze is Director of the college's Center for Environmental Studies and Professor of Biology & Environmental Science. Masucci corresponded with other college faculty and staff members throughout her study, including: David Baker, Associate Professor of Physics, and John Jennings, Physical Plant Director. Masucci collected data for fiscal year 2010.
Please describe any emissions sources that were classified as de minimis and explain how a determination of the significance of these emissions was made.
The following categories of emissions accounted for less than 1% of the total during fiscal year 2010: paper purchasing, fleet vehicles, personal mileage reimbursement, bus miles, wastewater, and fertilizer. For emission categories that were less than 1% of the college total during FY 2008 the present inventory used the upper-bound estimates from the FY 2008 inventory unless new data were readily available. New data were used for the following categories for FY 2010 (rather than the upper-bound estimates from the FY 2008 inventory): fleet vehicles, refrigerants and chemicals (which were found not de minimus during FY 2010), fertilizer, and personal mileage reimbursement. There was an error in the calculations of purchased paper in the FY 2008 inventory; the error is noted and corrected in the FY 2010 inventory document that has been uploaded to this website. The same amount of paper was purchased during FY 2008 and FY 2010. The resulting emissions from purchased paper were actually less than 1% during FY 2008 & FY 2010.
Please describe any data limitations related to this submission and any major assumptions made in response to these limitations.
Commuter gasoline consumption calculations are based on a detailed, extensive survey of the campus population. We assume survey respondents were representative. Solid waste quantities are estimates based upon frequencies with which dumpsters were emptied and estimates of average available volume filled upon emptying; total solid waste carried away per year (tons) was calculated assuming that the bins were filled to 100% capacity when emptied. Faculty and staff directly financed outsourced air travel records had missing or ambiguous destination data for 12% of flights. The average mileage of the remaining 88% of such flights was calculated and we assumed the 12% of flights with unknown mileages were of the same average mileage. Fleet vehicle calculations are based upon actual mileages of each campus-owned vehicle with personal miles deducted accordingly.
