Part 1. Greenhouse gas emissions inventory
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 2024 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:
Documentation to support the GHG inventory verification process:
Scope 1 GHG emissions
| Weight in MTCO2e | |
| Stationary combustion | 22,128 Metric tons of CO2 equivalent |
| Other sources (mobile combustion, process emissions, fugitive emissions) | 920 Metric tons of CO2 equivalent |
Total gross Scope 1 GHG emissions, performance year:
Scope 2 GHG emissions
| Weight in MTCO2e | |
| Imported electricity | 34,549 Metric tons of CO2 equivalent |
| Imported thermal energy | 0 Metric tons of CO2 equivalent |
Total gross Scope 2 GHG emissions, performance year:
GHG emissions from biomass combustion
Scope 3 GHG emissions
| Yes or No | Weight in MTCO2e | |
| Business travel | No | 0 Metric tons of CO2 equivalent |
| Commuting | Yes | 9,219 Metric tons of CO2 equivalent |
| Purchased goods and services | Yes | 50.80 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 | Yes | 153.20 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 Government of Canada.
Emissions related to Purchased Goods and Services are focused on paper purchases. Number of paper sheets are tracked each year by Print Services, which is then translated into a total weight and is then broken out by % of recycled content (0%, 30%, 100%) and emissions are then calculated. Emissions factors are taken from the BC Best Practices for Quantifying GHGs (which sources Environmental Paper Network).
Other sources include emissions related to water supplied to our campus and wastewater leaving campus. Volumes are collected through utility billing data to determine total annual volumes. Emissions factors are provided by Halifax Water, our municipal water utlity provider.
Part 2. Air pollutant emissions inventory
Annual weight of emissions for::
| Weight of Emissions | |
| Nitrogen oxides (NOx) | 43.99 Metric tons |
| Sulfur oxides (SOx) | 4.17 Metric tons |
| Carbon monoxide (CO) | 87.57 Metric tons |
| Particulate matter (PM) | 27.42 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 | 3.01 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 |
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.
