Areas of action
Basic geological research
Basic geological research forms the basis for understanding natural processes and phenomena, provides corresponding scientific explanations and enables the transfer of scientific findings into applied knowledge and projects.
Read moreEnvironmental change and quality of life
We identify current environmental issues and find solutions. These are based on multidisciplinary networking and active participation in the formulation of measures that ensure an environment worth living in.
Read moreGeohazard - geological hazards
We are strengthening research and development to identify the key spatio-temporal factors influencing the occurrence and development of geologically induced hazards.
Read moreEnergy transition and the use of carbon-free sources
Through cutting-edge scientific research, we aim to achieve a breakthrough in understanding the potential and usability of geothermal energy as a key strategic resource for the green energy transition and decarbonisation.
Read moreSustainable use of mineral and energy resources
We provide expert decision support in the fields of mineral resources, environmental protection and conservation of natural heritage. We enhance research on mineral and energy resources throughout their entire life cycle, including secondary raw materials.
Read moreDigital transformation with the goal of a digital twin
We are continuously pursuing key strategic directions in digital transformation, new technologies and the use of artificial intelligence, including cybersecurity and the systematic curation of GeoZS data.
