Has the institution conducted a GHG emissions inventory within the previous three years that includes all Scope 1 and 2 emissions? :
Yes

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?:
No

Total gross Scope 1 GHG emissions, performance year:
6,657.02 Metric Tons of CO2 Equivalent

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:

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:
85,372.14 Metric Tons of CO2 Equivalent

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?:
Yes

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.


Gross Scope 2 GHG emissions from purchased electricity (location-based):
12,926.17 Metric Tons of CO2 Equivalent

Gross Scope 2 GHG emissions from imported thermal energy (location-based) :
0 Metric Tons of CO2 Equivalent
