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:

Western uses SIMAP . The Sustainability Engagement Institute collects info from many units on campus for input into the calculator and uses the results to report to on and off campus entities.


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

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 12,725.13 Metric tons of CO2 equivalent
Other sources (mobile combustion, process emissions, fugitive emissions) 290.16 Metric tons of CO2 equivalent

Total gross Scope 1 GHG emissions, performance year:
13,015.29 Metric tons of CO2 equivalent

Gross Scope 2 GHG emissions, performance year (market-based):
Weight in MTCO2e
Imported electricity 649.23 Metric tons of CO2 equivalent
Imported thermal energy 0 Metric tons of CO2 equivalent

Total gross Scope 2 GHG emissions, performance year:
649.23 Metric tons of CO2 equivalent

Gross GHG emissions from biogenic sources, performance year:
0 Metric tons of CO2 equivalent

Does the GHG emissions inventory include Scope 3 emissions from the following sources?:
Yes or No Weight in MTCO2e
Business travel --- 3,581.44 Metric tons of CO2 equivalent
Commuting Yes 5,042.24 Metric tons of CO2 equivalent
Purchased goods and services Yes 19.14 Metric tons of CO2 equivalent
Capital goods --- ---
Fuel- and energy-related activities not included in Scope 1 or Scope 2 --- 0 Metric tons of CO2 equivalent
Waste generated in operations Yes 2,798.77 Metric tons of CO2 equivalent
Other sources --- ---

Total Scope 3 GHG emissions, performance year:
11,441.59 Metric tons of CO2 equivalent

A brief description of how the institution accounted for its Scope 3 emissions:

Western uses SIMAP . The Sustainability Engagement Institute collects info from many units on campus for input into the calculator and uses the results to report to on and off campus entities. It should be noted due to the COVID-19 pandemic our usual transportation survey was not administered so our most recent data collected was used for this report even though it falls outside the 3 year window. Updated student, staff, and faculty surveys will be administered next year to collect updated data.


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) 18.90 Tons
Sulfur oxides (SOx) ---
Carbon monoxide (CO) ---
Particulate matter (PM) ---
Ozone (O3) ---
Lead (Pb) ---
Hazardous air pollutants (HAPs) ---
Ozone-depleting compounds (ODCs) ---
Other standard categories of air emissions identified in permits and/or regulations ---

Do the air pollutant emissions figures provided include the following sources?:
Yes or No
Major stationary sources Yes
Area sources ---
Mobile sources Yes
Commuting Yes
Off-site electricity production ---

A brief description of the methodology(ies) the institution used to complete its air emissions inventory:

Western's Steam Plant is regularly audited by the Environmental Protection Agency and Clean Air Agency. Cleaver Brooks, a boiler maintenance contractor, performs air emissions inventory on the boilers which is submitted to above mentioned agencies.
