GHG Report for Colby College

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) | 11,701 metric tons of CO2e | 6.4 metric tons of CO2e | 8.1 metric tons of CO2e | 2% |
| Gross emissions (Scopes 1 + 2 + 3) | 16,605 metric tons of CO2e | 9.0 metric tons of CO2e | 11.5 metric tons of CO2e | 1% |
| Net emissions | 16,426 metric tons of CO2e | 8.9 metric tons of CO2e | 11.4 metric tons of CO2e | N/A |
