GHG Report for American Public University System
Submitted on January 15, 2009; last updated on January 16, 2009
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) | 1,029 metric tons of CO2e | 0.1 metric tons of CO2e | 9.6 metric tons of CO2e | 0% |
| Gross emissions (Scopes 1 + 2 + 3) | 2,242 metric tons of CO2e | 0.1 metric tons of CO2e | 20.8 metric tons of CO2e | 0% |
| Net emissions | 2,242 metric tons of CO2e | 0.1 metric tons of CO2e | 20.8 metric tons of CO2e | N/A |
Emissions Inventory Methodology and Boundaries
| Start date of the 12-month period covered in this report | January 1, 2007 |
| 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.
All APUS owned and operated buildings are included as well as leased office and administrative spaces. Leased IT spaces are not included in the report. |
|
| Emissions calculation tool used | Clean Air-Cool Planet |
|
Please describe why this tool was selected.
APUS contracted with Sightlines to complete the GHG inventory. Sightlines utilizes the Clean Air - Cool Planet Campus Carbon Calculator as a framework for its analysis. |
|
|
Please describe the source(s) of the emissions coefficients used.
Emissions coefficients used are from the Campus Carbon Calculator v5. |
|
| 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.
Sightlines staff performed a two day site visit to collect appropriate data for processing. |
|
|
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.
Solid waste is unable to be calculated at this time due to data limitations. |
