The International Commission on Geoheritage (ICG) is a prominent body operating as a permanent commission under the International Union of Geological Sciences (IUGS). Focused on the preservation of geological heritage, the ICG aims to promote global awareness and understanding of geological features and sites of significance. It oversees numerous initiatives and projects relating to geological heritage, including geological heritage sites and heritage stones, which contribute richly to Earth’s history.

The commission is instrumental in setting standards and definitions through its various subcommittees, such as those related to site designation and geo-collections. Each of these subcommittees focuses on specific aspects of geoheritage, ensuring a comprehensive approach to research and conservation efforts. The ICG also publishes annual reports and conducts events like the IUGS Geoheritage Event, fostering international collaboration among geoscientists, conservationists, and educators. Through its work, the ICG reinforces the importance of protecting our planet's geological diversity and heritage for future generations.
