Our Journey to Net Zero

Campus Energy Consumption

Our employees, students and guests are provided with consumption data for the buildings they use in order for them to reduce greenhouse gas emissions in compliance with the Climate Change (Scotland) Act.

To underline the University’s commitment towards a more sustainable future, an energy and sustainability manager was appointed in September 2020 with a remit to drive energy efficiencies. If energy consumption across the campus has increased, they look at Building Energy Management System (BEMS) controls to determine if further energy efficiency actions can be implemented to mitigate the further increase. RGU also publishes monthly energy consumption for every building on campus.

Like other public sector bodies, Robert Gordon University has a duty to contribute to the Scottish Government’s climate change targets.  RGU must report on their annual greenhouse gases and efforts to tackle climate change. There are accepted standards used to understand, quantify and report Green House Gas (GHG) emissions.

  • Scope 1 emissions refer to the GHGs that RGU creates directly, for example, while running boilers.
  • Scope 2 emissions are made by RGU indirectly, so when the University buys electricity or energy for heating buildings.
  • Scope 3 emissions usually account for the highest proportion of total emissions and are comprised of all other indirect emissions.

The University publishes a Climate Change report every year: 

Energy Consumption

Each building's electricity & gas consumption is compared to the same month on the previous year e.g. August 2023 against August 2022.

˅ No colour highlight - buildings which have attained an electricity / gas reduction

^ Light red highlight - Buildings which have consumed more electricity / gas 

^^ Dark red highlight - Buildings which have consumed more than over 40% electricity / gas

From 1 August 2023 to 31 August 2023, RGU has consumed 1,134,071 kWhs of electricity & gas which has produced 244 tonnes of Greenhouse Gas (GHG) emissions into our planet’s atmosphere. Please note this is equivalent to GHG emissions to 625,506 miles driven by an average passenger vehicle.
This represents a 3.2% increase in electricity & gas consumption compared to the previous academic year 2021/22 at 1,098,914 kWhs.



Paper Consumption

The consumption of paper is a substantial emitter of Greenhouse Gas (GHG) emissions. Paper-based products require trees for production, which is unfortunate as trees absorb GHG emissions. To avert  rising global temperature, we must greatly reduce our consumption of paper to maintain our planet’s existing tree population. We can do this by utilising our existing digital technology, for example viewing documents on screens, sending emails and taking digital notes.

For the year 1 August 2022 to 31 July 2023, RGU has purchased 18.5 tonnes of paper, which is the equivalent of 377 trees. It is estimated that a standard pine tree, with 45ft of the usable trunk and a diameter of 8 inches, will produce around 10,000 sheets of paper.

The table presents each building's paper consumption from 1 August 2022 to 31 July 2023. ^ Red cells highlight buildings which have consumed more this academic year compared to the previous academic year:
