A brief description of when and why the GHG emissions baseline was adopted:
The college was required to report on GHG inventory starting in 2006 and 2010 was chosen as the baseline to match our climate action targets.

A brief description of the institution’s GHG emissions reduction initiatives:
St. Lawrence College has been taking action to mitigate its GHG emissions from buildings. These initiatives include adoption of PV (FIT Program), geothermal installations in the Hello Future capital project, design and adoption of air source heat pumps and lighting retrofits. Additional measures planned that will assist in further reducing GHG emissions include retro-commissioning of existing HVAC equipment, boiler and demand control optimization, lighting efficiency upgrades and incremental building envelope improvements. Completed in 2021 as part of a sustainability driven strategic initiative, the College’s “Greenhouse Gas Reduction Roadmap & Action Plan” provides a deep energy retrofit assessment for each campus and includes detailed technical options and financial implications for phased GHG emission reductions – in alignment with deferred maintenance needs. The approach is to:
• Conserve energy through effective building utilization and energy reduction measures.
• Electrification of natural gas equipment towards the end of useful life.
• Continue to capture upgrades and retrofits within the capital budget and planning process.
• Integrate climate wise and GHG emission reduced technology into major retrofits.
• Design new buildings to target carbon neutrality.
• Manage the operating costs of electrification through the increased adoption of PV, conservation, and continuous operational improvements (periodic retro-commissioning).

Data source(s) and notes about the submission:
The change in imported electricity (from baseline year 2010) is due to the drop in the emissions factors over this time. Between 2010 and 2022, Ontario had a decrease of 75% in emissions factors and Quebec (where our Cornwall campus’ electricity originates) saw a 43% drop.
