GHG Report for American University
Submitted on May 15, 2009; last updated on April 2, 2010
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)||36,274 metric tons of CO2e||3.6 metric tons of CO2e||10.8 metric tons of CO2e||4%|
|Gross emissions (Scopes 1 + 2 + 3)||56,743 metric tons of CO2e||5.6 metric tons of CO2e||17.0 metric tons of CO2e||2%|
|Net emissions||55,410 metric tons of CO2e||5.5 metric tons of CO2e||16.6 metric tons of CO2e||N/A|
Emissions Inventory Methodology and Boundaries
|Start date of the 12-month period covered in this report||May 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.
The Greenhouse Gas Inventory was calculated based on available data for University managed buildings, including the main University Campus and surrounding campus affiliated buildings. Future GHGI goals include the collection of data from other university managed real estate (e.g. Institution offices, etc.).
|Emissions calculation tool used||Clean Air-Cool Planet|
Please describe why this tool was selected.
1. Clean Air-Cool Planet's (CACP) Campus Carbon Calculator is consistent with GHG Protocol standards.
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?||External consultant|
Please describe the process of conducting the inventory.
An external consultant was retained to conduct the inventory. They were provided with contact information to work with relevant campus staff across the different data collection areas.
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.
Due to incomplete, unreliable, or altogether absent data sets for specific years and across some emission sources, completion of the inventory for FY2007 required the acknowledgement of data limitations and the proposition of assumptions/methodologies to reconcile them. For a detailed account of all assumptions and limitations see section 4 of the greenhouse gas narrative attached at the bottom of this web page.
