This book brings together reflections from the session “Geoethics at the Heart of All Geoscience: Serving the Public Good,” held under the theme “Geoethics and Societal Relevance of Geosciences” at the 37th International Geological Congress (IGC) in Busan, Republic of Korea. The session was co-sponsored by the International Association for Promoting Geoethics (IAPG) and the Commission on Geoethics (CG) of the International Union of Geological Sciences (IUGS). The wealth of contributions presented, rooted not only in the broad field of geosciences but also intersecting with diverse scientific, humanistic, and social disciplines, makes this volume a representative and insightful compendium. It exemplifies the cultural and technical-scientific diversity of perspectives that geoethics inspires within the geoscientific community, highlighting its ability to foster interdisciplinary dialogue and address complex global challenges through an ethical lens.
