GHG Report for Portland State University

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) 27,017 metric tons of CO2e 1.2 metric tons of CO2e 5.1 metric tons of CO2e 12%
Gross emissions (Scopes 1 + 2 + 3) 47,342 metric tons of CO2e 2.0 metric tons of CO2e 9.0 metric tons of CO2e 7%

Emissions Inventory Methodology and Boundaries

Start date of the 12-month period covered in this report July 1, 2011
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.

Space PSU is leasing from others is omitted.

Emissions calculation tool used Clean Air-Cool Planet
Please describe why this tool was selected.

Most widely used by colleges and universities.

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? Sustainability office staff
Please describe the process of conducting the inventory.

Campus Sustainability Office(CSO) staff contacted various campus departments for reports of the required data during FY12. In some cases, CSO staff contacted vendors directly (travel agencies, bus companies, office supply vendors). In other cases, conversions needed to be made by CSO staff in order to acquire data points that are not tracked by the University. The data gathering process began in summer 2012, and concluded at the end of 2012 just before submission of this assessment.

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.

We have some data limitations for scope 3 emissions sources such as travel. Air travel purchases are made through travel agencies as well as personal reimbursements. At this time, PSU does not have a reliable way to estimate the total # air miles traveled and reported through personal reimbursements. Therefore, air miles tracked by the three main contracted travel agencies were counted, but not miles through personal reimbursement.Faculty/staff/student air travel is not tracked separately, therefore one total number for air miles through travel agencies is reported for campus. Additionally, train, bus, shuttle, and taxi miles are not reported, again due to our inability to track mileage through personal reimbursement forms.

Bus travel miles for sporting events were also not reported due to lack of tracking by vendors.

Anaerobic digestion at water treatment facility, as well as CH4 recovery and electricity generation at the landfill are happening, at least for a *portion of water and waste treated. PSU has no way of knowing what portion of our total waste water or lanfilled waste falls into these categories, versus others such as anaerobic treatment or CH4 flaring. Total waste water was allocated to anaerobic digestion and half of total waste allocated to CH4 recovery and electricity generation, with the other half allocated to CH4 collection & flaring.

Purchased paper emissions represents data from the four main paper vendors supplying the University.
