Measuring Our Impact
We follow industry-standard protocols to classify carbon emissions into three categories:
- Scope 1: Direct emissions from college-owned activities (e.g., fuel use for heating).
- Scope 2: Indirect emissions from the generation of purchased electricity.
- Scope 3: Indirect emissions from sources not owned or directly controlled by the College, such as waste disposal and business travel
Energy Efficiency Initiatives:
- Replacement of old heating systems with modern heating and cooling solutions.
- Switching to LED lighting across campuses
- All new buildings to operate on renewable electricity
Location-based and market-based emissions
Official (GHG) protocols require both location and market-based emissions to be reported alongside one another. The two methods are outlined below:
- Location-based emissions is the emissions generated from electricity that comes from the national grid energy supply. This method utilises location-based factors, which provide the average emissions associated with electricity production, transmission, and distribution for a country or region.
- Market-based emissions is the emissions from electricity sources or products that the consumer has specifically chosen. This method utilises supplier-specific factors as a preference, which provide the emissions associated with a specific tariff provided by a specified energy supplier.
Market-based emissions consider the emission intensity of different energy sources, so emissions will be lower where renewable energy has been purchased. The majority of the College’s energy suppliers are market-based. As and when contractual arrangements allow, the College will seek to further increase market-based energy sources.
