The University records and reports its Scope 1 and 2 carbon emissions in accordance with the Greenhouse Gas Protocol. Scope 1 emissions are direct emissions primarily from gas used for heating buildings and Scope 2 emissions are indirect, coming mainly from electricity used in buildings.
The University purchases 100% renewable electricity, however its carbon emissions are still measured according to the UK National Grid average carbon emissions, which is in line with the Higher Education Statistics Authority methodology. This means it is not enough to purchase renewable electricity; we must go further, reducing reliance on gas, reducing electricity use and increasing on-site or sourcing locally generated renewable power.
The University aims to reduce its reliance on natural gas, which is mainly used to heat buildings, by replacing gas heat sources across the estate with electric, thereby reducing its Scope 1 emissions. The forecast reduction in carbon from the National Grid makes electricity a lower carbon heat source than gas in the longer term.
Additional activities include:
- Establishing district heating networks at Old Road Campus and the Science Area, and heat pump technology to be used across the estate to increase electrical efficiency.
- More efficient use of energy by encouraging engagement in energy saving, retrofitting buildings to reduce heat loss and using energy-efficient appliances. These measures will reduce our Scope 2 emissions.
- Every effort will be made to reduce our emissions as much as possible, however, carbon offsetting will be required to cover residual emissions. Offsetting will only be used from 2030 onwards.
