Institution-catalyzed carbon offsets generated 0 Metric tons of CO2 equivalent 0 Metric tons of CO2 equivalent
Carbon storage from on-site composting 0 Metric tons of CO2 equivalent 0 Metric tons of CO2 equivalent
Carbon storage from non-additional sequestration 0 Metric tons of CO2 equivalent ---
Carbon sold or transferred 0 Metric tons of CO2 equivalent 0 Metric tons of CO2 equivalent
Net carbon sinks 0 Metric tons of CO2 equivalent 0 Metric tons of CO2 equivalent

If total performance year carbon sinks are greater than zero, provide:

A brief description of the carbon sinks, including vendor, project source, verification program and contract timeframes (as applicable):

Our focus for the past number of years has been investing in GHG reduction projects on campus however we are in also exploring power purcahsing agreements and renewable energy credits related to renewable energy (wind) projects. 


Adjusted net GHG emissions

Adjusted net Scope 1 and Scope 2 GHG emissions:
Performance year Baseline year
Adjusted net GHG emissions 57,597 Metric tons of CO2 equivalent 106,178 Metric tons of CO2 equivalent

Performance and baseline periods

Start and end dates of the performance year and baseline year (or three-year periods):
Performance year Baseline year
Start date April 1, 2023 April 1, 2009
End date March 31, 2024 March 31, 2010

A brief description of when and why the GHG emissions baseline was adopted:

The baseline year (2009-2010) is used in our University Sustainability Plan to compare progressive targets to for water, energy, GHGs. This year is when accurate data could be reliably accessed. 


Part 1. Reduction in GHG emissions per person

Weighted campus users

Figures needed to determine “Weighted Campus Users”:
Performance year Baseline year
Number of students resident on-site 2,539 2,259
Number of employees resident on-site 7 9
Number of other individuals resident on-site 0 5
Total full-time equivalent student enrollment 19,161 15,685
Full-time equivalent of employees 6,091 5,592
Full-time equivalent of students enrolled exclusively in distance education 393 160
Weighted Campus Users 19,280.75 16,409.75

Metrics used in scoring for Part 1

Adjusted net Scope 1 and 2 GHG emissions per weighted campus user:
Performance year Baseline year
Adjusted net Scope 1 and 2 GHG emissions per weighted campus user 2.99 Metric tons of CO2 equivalent 6.47 Metric tons of CO2 equivalent

Percentage reduction in adjusted net Scope 1 and Scope 2 GHG emissions per weighted campus user from baseline:
53.83

Part 2. GHG emissions per unit of floor area

Healthcare space 929 Square meters
Other energy intensive space 208,399 Square meters

EUI-adjusted floor area, performance year:
1,107,926.52 Gross square meters

Metric used in scoring for Part 2

Adjusted net Scope 1 and 2 GHG emissions per unit of EUI-adjusted floor area, performance year:
0.05 MtCO2e per square meter

A brief description of the institution’s GHG emissions reduction initiatives:

In the 2023/24  fiscal year, a variety of projects were undertaken to reduce greenhouse gases and mitigate the impacts of climate change including: 

  • Deep energy retrofit of the Killam Library (one of the largest and most energy intensive biuldings on campus)
  • Expansion of the geoexchange system on the engineering campus to connect it to more buildings
  • Installed solar PV on the Arts Centre expansion
  • Working with FM planners and project managers/operators to build energy and water efficiency into operational and facilities renewal. Examples of implemented projects include air handling unit replacements with CO2/ and DCV controls, heat pump replacements with high efficiency units, high-efficiency capital construction projects, and equipment set back schedules. 
  • Re-commissioning of 2 major buildings on our campus. 
  • We also updated our Climate Change Operations Plan and Energy and Green Building Plan in 2022.

Data source(s) and notes about the submission:

This information includes all campuses including Halifax and Agricultural campuses. The baseline year emissions were modified to include the AC campus for fair comparison as the merger to add another campus to Dalhousie happened in 2012.
