Geoethics is an interdisciplinary field between Geosciences and Ethics which involves Earth and Planetary Sciences as well as applied ethics. It deals with the way of human thinking and acting in relation to the significance of the Earth as a system and as a model. Scientific, technological, methodological and social-cultural aspects are included (e.g. sustainability, development, geodiversity and geoheritage, prudent consumption of mineral resources, appropriate measures for predictability and mitigation of natural hazards, geosciences communication, museology, etc.), their liaison with concepts of geoeducation is evident. Also the necessity of considering appropriate protocols, scientific integrity issues and a code of good practice - regarding the study of the abiotic world - is covered by this discipline developed by the convener (V. Nemec with L. Nemcova) since 1991. Studies on planetary geology (sensu lato) and astrobiology also require a geoethical approach (as suggested by the co-convener J. Martínez-Frías). It is necessary to incorporate geoethical principles in the optimal way into the consciousness and the daily life of the global society. All efforts of not only Earth and Planetary scientists, ecologists and pedagogues but also of other professions including managers, leaders, politicians and statesmen at any level should respect – in the sense of geoethics – their own responsibility for the fate of our planet and of all its inhabitants including the future generations. Geological factors need to be reflected and respected in any concept of environ-mental sustainability. Thanks to the interdisciplinary approach a need arises to seek new priorities emphasizing more and more the solidarity of human kind – defined by the International Declaration of Geoethics.
