Has the institution conducted a GHG emissions inventory within the previous three years that includes all Scope 1 and 2 emissions? :
A copy of the most recent GHG emissions inventory:
A brief description of the methodology and/or tool used to complete the GHG emissions inventory:
Campus Sustainability Office(CSO) staff contacted various campus departments for reports of the required data. For Scope 1, Scope 2, and some of Scope 3 emission, data is entered into SIMAP to determine annual emissions. For purchased goods and services PSU utilizes the CBEI (Consumption Based Emissions Inventory) that was developed by the Oregon DEQ to calculate emissions, based on dollars spent.
Has the GHG emissions inventory been validated internally by personnel who are independent of the GHG accounting and reporting process and/or verified by an independent, external third party?:
A brief description of the GHG inventory verification process:
Documentation to support the GHG inventory verification process:
Gross Scope 1 GHG emissions, performance year:
| Weight in MTCO2e | |
| Stationary combustion | 6,519.67 Metric Tons of CO2 Equivalent |
| Other sources (mobile combustion, process emissions, fugitive emissions) | 137.35 Metric Tons of CO2 Equivalent |
Total gross Scope 1 GHG emissions, performance year:
Gross Scope 2 GHG emissions, performance year (market-based):
| Weight in MTCO2e | |
| Imported electricity | 12,926.17 Metric Tons of CO2 Equivalent |
| Imported thermal energy | 0 Metric Tons of CO2 Equivalent |
Total gross Scope 2 GHG emissions, performance year:
Gross GHG emissions from biogenic sources, performance year:
Does the GHG emissions inventory include Scope 3 emissions from the following sources?:
| Yes or No | Weight in MTCO2e | |
| Business travel | Yes | 8,458.73 Metric Tons of CO2 Equivalent |
| Commuting | Yes | 8,758.98 Metric Tons of CO2 Equivalent |
| Purchased goods and services | Yes | 42,407.27 Metric Tons of CO2 Equivalent |
| Capital goods | Yes | 24,350.33 Metric Tons of CO2 Equivalent |
| Fuel- and energy-related activities not included in Scope 1 or Scope 2 | No | 652.37 Metric Tons of CO2 Equivalent |
| Waste generated in operations | Yes | 744.46 Metric Tons of CO2 Equivalent |
| Other sources | No | --- |
Total Scope 3 GHG emissions, performance year:
A brief description of how the institution accounted for its Scope 3 emissions:
Every fiscal year Campus Accounting Services provides us a document of all operational purchases from the University. Account codes are removed that are considered transfers of money (includes payroll, insurance, etc...), double counting (account that we have collected usage information and entered into SIMAP) and diminishing returns (any account code with less than $1000 spent in a fiscal year). Using the CBEI, created by Oregon DEQ, we match purchases to emission factors. Since the CBEI was based on FY13 dollars, we also account for inflation to try to keep an accurate account of emissions.
Has the institution completed an inventory within the previous three years to quantify its air pollutant emissions?:
Annual weight of emissions for::
| Weight of Emissions | |
| Nitrogen oxides (NOx) | 3.54 Tons |
| Sulfur oxides (SOx) | 0.94 Tons |
| Carbon monoxide (CO) | 2.72 Tons |
| Particulate matter (PM) | 0.31 Tons |
| Ozone (O3) | --- |
| Lead (Pb) | --- |
| Hazardous air pollutants (HAPs) | --- |
| Ozone-depleting compounds (ODCs) | --- |
| Other standard categories of air emissions identified in permits and/or regulations | 0.30 Tons |
Do the air pollutant emissions figures provided include the following sources?:
| Yes or No | |
| Major stationary sources | Yes |
| Area sources | No |
| Mobile sources | No |
| Commuting | No |
| Off-site electricity production | No |
A brief description of the methodology(ies) the institution used to complete its air emissions inventory:
In compliance with Oregon Department of Environmental Quality guidelines, emissions are calculated based on equations provided within our operating permits for the boilers and turbine. Briefly, each emission (PM, SO2, NOX, etc.) has an associated pollutant emission calculation for emissions where emissions (tons) = Emission factor (lb/1,000 gallons) * Fuel Oil Quantity (1,000 gallons) / (divided by) 2,000 lbs / ton which provides the reportable quantity listed in the attached submittals.
