Within the scope of the balance, the GHG emissions given in CO2 equivalents (CO2-e) of the categories energy, new buildings, mobility, use of materials, as well as food supply canteen at all locations of Graz University of Technology (main locations and secondary locations) were evaluated. The accounting was carried out according to the common method of the Alliance for Sustainable Universities in Austria using the ClimCalc_edu tool. For the accounting for the buildings the environmental impacts were estimated on the case of the EBS building (Energy Based Systems) as proxy to estimate yearly GHG-emissions.
The results of the GHG accounting 2017 show total emissions of about 27,000 total GHG in t CO2-e for the year 2017 at Graz University of Technology. Most of the emissions come from electricity, business trips, new buildings and district heating (altogether 22,200 t CO2-e or 82% of the total emissions). Electricity, at 29%, accounts for almost one third of the total greenhouse gas emissions of Graz University of Technology. Heat (mainly district heating) accounts for 16%. Construction of new buildings and business trips of the staff take up the second highest category in terms of CO2-e, each with about 19% of CO2-e. Commuting students (4%), commuting employees (4%) and stays abroad of students and employees (5%) are at a similarly high level. The rest (canteen, material consumption, IT equipment, other fuels, etc.) together account for about 4% of the total greenhouse gas emissions of Graz University of Technology.
The GHG accounting of Graz University of Technology shows the status quo and is a first important step to determine the energy performance of Graz University of Technology in terms of sustainability. For a complete consideration in the context of sustainability reporting, a comprehensive ecological evaluation is necessary. For this, an exact recording of the system boundaries is of particular importance, as well as the further use of evaluation methods, as they have already been used in previous sustainability reports.
