Part 1. Greenhouse gas emissions inventory

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:
GHG Emissions reported per the requirements of Canada's Output-Based Pricing System regulations.

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?:
Yes

A brief description of the GHG inventory verification process:
Verified as part of ISO 14064-3:2006 certification.

Documentation to support the GHG inventory verification process:
Scope 1 GHG emissions
Gross Scope 1 GHG emissions, performance year:
Weight in MTCO2e
Stationary combustion 54,163 Metric tons of CO2 equivalent
Other sources (mobile combustion, process emissions, fugitive emissions) 0 Metric tons of CO2 equivalent

Total gross Scope 1 GHG emissions, performance year:
54,163 Metric tons of CO2 equivalent

Scope 2 GHG emissions
Gross Scope 2 GHG emissions, performance year (market-based):
Weight in MTCO2e
Imported electricity 4,670 Metric tons of CO2 equivalent
Imported thermal energy 0 Metric tons of CO2 equivalent

Total gross Scope 2 GHG emissions, performance year:
4,670 Metric tons of CO2 equivalent

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

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

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

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

Part 2. Air pollutant emissions inventory

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) 90.89 Metric tons
Sulfur oxides (SOx) ---
Carbon monoxide (CO) 36.97 Metric tons
Particulate matter (PM) 0.87 Metric 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 ---

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

None
A brief description of the methodology(ies) the institution used to complete its air emissions inventory:
Many of the University Buildings have air permits in place, each requiring an Emissions Summary and Dispersion Modelling report. An Emissions Summary and Dispersion Modelling ("ESDM") Report is a report that, as its name implies, covers an assessment of air pollution emissions from a facility, and how they disperse after they are released. An ESDM report must specifically include the content listed in, and use the methodologies described in, section 26 of O. Reg. 419/05. In this way, Western is able to keep track of it's emissions and maintain compliance.

Optional Fields

Gross Scope 2 GHG emissions from imported thermal energy (location-based) :
