Abstract: Sustainable development has become one of the burning issues on a global, local and individual levels as a result of climate changes, pollution, rapid development and changes in the global information, economic, industrial and business sectors and value systems. In this sense, education for sustainable development, as part of lifelong learning, has become one of the most important strategic and educational policy issues in Serbia. The aim of this paper is to highlight the potential of geography as a school subject, with special reference to the role of the subject matter of geoheritage and geodiversity in education for sustainable development. The aim of pointing the benefits of integrated and out-of-classroom approaches in teaching geography, which favour an active, experiential and exploratory approach to learning about geodiversity and geoheritage, is that students can acquire competencies in sustainable development. As outcomes of geography classes, competencies also represent a basis for raising awareness and increasing accountability and responsibility in individuals for preserving geoheritage and geodiversity as part of the Serbian national treasure.
