GHG Report for Linfield 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) 3,364 metric tons of CO2e 2.0 metric tons of CO2e 3.4 metric tons of CO2e 0%
Gross emissions (Scopes 1 + 2 + 3) 7,774 metric tons of CO2e 4.5 metric tons of CO2e 7.9 metric tons of CO2e 0%

Emissions Inventory Methodology and Boundaries

Start date of the 12-month period covered in this report July 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 Linfield College McMinnville Campus was included in this survey. The Linfield College/Good Samaritan School of Nursing was not included, since that campus facility is operated by the Legacy Good Samaritan Hospital in Portland, Oregon.
Emissions calculation tool used Clean Air-Cool Planet
Please describe why this tool was selected.

The CA-CP tool was selected because it is widely used, thus enabling meaningful comparisons with other similar institutions.
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? Class
Please describe the process of conducting the inventory.

The inventory was initially conducted, and data was analyzed, by the Environmental Studies senior capstone class as described in their report. The Advisory Committee on the Environment and Sustainability (ACES) decided to submit results obtained using the CACP calculator instead of the capstone class calculations in order to better compare results between institutions and to track changes from year to year. The data input into the CACP calculator were obtained as follows:
(1) Travel data were assembled by the capstone class using records of the Controller’s office, International Programs, and Admissions.
(2) Commuter miles were estimated from a survey conducted by the capstone class.
(3) Natural gas and Electricity usage were obtained from Physical Plant records.
The results of the CACP calculator compare well with those of the capstone class, except for emissions associated with air miles. In that case, the CACP calculator includes a multiplicative factor of 2.8 to account for the increased impact of high altitude emissions, while the capstone class’s calculations, in accordance with many other emissions calculators, merely report the direct CO2 emissions. Because of Linfield’s policy of paying for the first round-trip airline ticket for each student studying abroad, the CO2 emissions associated with airline travel are particularly high, especially when estimated using the CACP calculator. Also, the study-abroad airline miles are for all Linfield students, while all other values reported in this calculator are only for McMinnville campus.
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 not currently tracked by Linfield College, and emissions associated with it have not been included. Emissions associated with fertilizer use and with refrigerants or other chemicals have likewise not been tracked.
