2006 GHG Report for Lewis & Clark College
Submitted on September 15, 2008; last updated on November 26, 2008
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) | 12,267 metric tons of CO2e | 3.2 metric tons of CO2e | 9.8 metric tons of CO2e | 5.2% |
| Gross emissions (Scopes 1 + 2 + 3) | 17,757 metric tons of CO2e | 4.6 metric tons of CO2e | 14.2 metric tons of CO2e | 3.6% |
| Net emissions | 17,123 metric tons of CO2e | 4.4 metric tons of CO2e | 13.7 metric tons of CO2e | N/A |
Emissions Inventory Methodology and Boundaries
| Start date of the 12-month period covered in this report | January 1, 2005 |
| Consolidation methodology used to determine organizational boundaries | No information provided. |
|
If any institution-owned, leased, or operated buildings or other holdings that should fall within the organizational boundaries are omitted, briefly explain why.
A small amount of leased space and buildings outside the campus boundary boundary is omitted due to lack of data. This is estimated to be less than 1% of the reported data. |
|
| Emissions calculation tool used | Clean Air-Cool Planet |
|
Please describe why this tool was selected.
This is the calculator that has been used historically at L&C. |
|
|
Please describe the source(s) of the emissions coefficients used.
Emissions coefficients for purchased electricity were obtained from the Oregon Department of Energy which develops these on an annual basis for each of the utilities in the state. The CA-CP Campus Carbon Calculator's default emissions coefficients were used for all other sources. |
|
| Which version of IPCC's list of global warming potentials did you use? | Second Assessment Report |
| Who primarily conducted this emissions inventory? | Student researcher(s) |
|
Please describe the process of conducting the inventory.
No information provided. |
|
|
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.
No information provided. |
