In 2024, the total energy consumption (heat and electricity) of all HSG premises (Rosenberg campus and all rented properties) amounted to around 5'000'000 kWh. Thanks to various operational, energy efficiency and property portfolio optimisations, consumption has been reduced by almost 10% over the last five years, following significant reductions in previous years.
The HSG's water consumption in 2024 amounted to a good 11'000 m3. Consumption remains at a similar level to 2019, even though student numbers have risen by around 11% since then.
HSG's total greenhouse gas (GHG) emissions amounted to around 21'500 tCO₂e in 2024. This represents a reduction of around 4% compared to the 2019 baseline. Further information on the calculation methodology and emission sources can be found in HSG's GHG report.
