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:
The CAN/CSA‐ISO 14064‐1‐06 Greenhouse Gases ‐ Part 1: Specification with Guidance at the Organization Level for Quantification and Reporting of Greenhouse Gas Emissions and Removals (Adopted ISO 14064-1:2006, first edition, 2006‐03‐01) standard was used as a framework for the GHG inventory report. Calculations were derived from The Climate Registry (TCR) ‐ General Reporting Protocol. Emission factors used were taken from TCR 2020 Default Emission Factors document and the Nova Scotia Power website.
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:
Stantec Consulting validated the GHG report methods and outline.
Documentation to support the GHG inventory verification process:
Gross Scope 1 GHG emissions, performance year:
| Weight in MTCO2e | |
| Stationary combustion | 26,907 Metric tons of CO2 equivalent |
| Other sources (mobile combustion, process emissions, fugitive emissions) | 911.60 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 | 49,066 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 | No | 0 Metric tons of CO2 equivalent |
| Commuting | Yes | 10,912 Metric tons of CO2 equivalent |
| Purchased goods and services | Yes | 151.10 Metric tons of CO2 equivalent |
| Capital goods | --- | 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 | Yes | 233.30 Metric tons of CO2 equivalent |
Total Scope 3 GHG emissions, performance year:
A brief description of how the institution accounted for its Scope 3 emissions:
Commuting emissions are based on commuter survey results collected by the University. Travel is then broken down by: drive-alone; drive-carpool; public transit; biking; and walking. Assumed daily travel km per person multiplied by campus population is used to determine total km per mode of transportation. GHG emission factors by transportation mode is collected from Fuel consumption ratings Gov't of Canada.
Purchased good and services is determined based on paper purchased on Campus, split up between virgin and recycled products. Emission factors based on BC Best practices reference tables for paper.
Other sources includes emissions from water usage on Campus. Emissions factors provided by the water utility are utilized along with water consumed on campus.
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) | 23.96 Metric tons |
| Sulfur oxides (SOx) | 3.92 Metric tons |
| Carbon monoxide (CO) | 79.04 Metric tons |
| Particulate matter (PM) | 23.93 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 | 2.79 Metric tons |
Do the air pollutant emissions figures provided include the following sources?:
| Yes or No | |
| Major stationary sources | Yes |
| Area sources | Yes |
| Mobile sources | No |
| Commuting | No |
| Off-site electricity production | Yes |
A brief description of the methodology(ies) the institution used to complete its air emissions inventory:
Other = VOCs
This emission data was generated in the process of filling the federal National Pollutant Release Inventory (NPRI) for all campuses (Halifax and Agricultural). NPRI requirements and methodology was employed in completing the inventory.

Additional documentation to support the submission:
Data source(s) and notes about the submission:
The location based GHG emission factors for Scope 2 purchased electricity are already used in the Scope 2 numbers. The most recent GHG emission factors provided by NS Power (Dalhousie's electricity provider) were used. This makes the accounting of GHG emissions for purchased electricity very accurate.
