GHG Report for Bates College
Submitted on September 23, 2008; last updated on March 15, 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) | 16,359 metric tons of CO2e | 9.9 metric tons of CO2e | 10.6 metric tons of CO2e | 52% |
| Gross emissions (Scopes 1 + 2 + 3) | 18,108 metric tons of CO2e | 10.9 metric tons of CO2e | 11.8 metric tons of CO2e | 47% |
| Net emissions | 9,621 metric tons of CO2e | 5.8 metric tons of CO2e | 6.3 metric tons of CO2e | N/A |
Emissions Inventory Methodology and Boundaries
| Start date of the 12-month period covered in this report | July 1, 2008 |
| 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.
Rental properties are omitted in the FY 2009 data. |
|
| Emissions calculation tool used | Clean Air-Cool Planet |
|
Please describe why this tool was selected.
Many other colleges and univeristies have used this tool. |
|
|
Please describe the source(s) of the emissions coefficients used.
Emissions coeeficients used in CA-CP calculator. |
|
| Which version of IPCC's list of global warming potentials did you use? | No information provided |
| Who primarily conducted this emissions inventory? | Sustainability office staff |
|
Please describe the process of conducting the inventory.
The sustainability coordinator gathered scope 1 stationary fuel data and scope 2 purchased electricity data from detailed budget books, which included quantities consumed in gallons, ccfs (converted to MMBtus), and kWhs. Mobile combustion from the College fleet was calculated using the annual mileage driven by each vehicle (recorded by maintenance staff). Faculty and staff commuting was calculated using each employee's address, multiplying the number of miles driven by how many days a week they work based on job class (i.e., part time academic year, full time academic year, part time year round, full time year round, etc.). Air travel was estimated by sampling travel reimbursement forms. |
