Teil VI: Die Ökobilanz der Universität Osnabrück

Within the development of the “Osnabrück Environmental Management Model for Universities,” an environmental audit for the university has been carried out for the first time. It was implemented by way of a Life Cycle Assessment (LCA) based on ISO 14 040. Following this, an LCA includes the four steps:goal and scope definition, inventory analysis, impact assessment andinterpretation. The impact assessment phase of the LCA was carried out following the ”UBA-Method” of the German Federal Environmental Agency (UBA) which is based on the method of impact categories described in ISO 14 040 and implemented in the software Umberto^®. The most significant results are that the University contributes “considerably” towards both categories, “Depletion of fossil energy resources” and “Climate change”. The main causes of this are electricity and heat consumption as well as traffic. In order to improve its environmental situation, the university has been recommended to reduce its CO₂ emissions, its consumption of fossil energy resources and its methane emissions.
