Founded in 1961 as a successor to earlier international geological efforts, it serves as one of the world's largest scientific unions, representing over one million geoscientists through more than 120 adhering national member organizations and over 50 affiliated international bodies. Headquartered with a permanent secretariat in , , IUGS operates as a 501(c)(3) non-profit entity registered in the United States. IUGS's core objectives include fostering the development of geological standards, enhancing and in earth sciences, representing geosciences in international forums, and encouraging interdisciplinary research on global challenges such as , , and natural hazards. It achieves these goals through a structured system led by an Executive Committee—comprising a President, Secretary General, , and Vice Presidents—elected by its Governing , which includes delegates from member organizations. As a member of the (ISC), IUGS collaborates closely with entities like on initiatives such as the International Geoscience Programme (IGCP), which funds over 50 projects annually to address pressing issues. Key activities of IUGS encompass organizing the quadrennial International Geological Congress (IGC), the premier global event for geoscientists that draws tens of thousands of participants to discuss advancements in fields like , , and geoheritage. It also supports specialized commissions, such as the (ICS), which establishes the international geological timescale, and the Commission on Geoheritage, which designates and promotes geological heritage sites worldwide. Recent initiatives include advocating for International Geodiversity Day on October 6, recognized by in 2021, and programs like Deep-time Digital Earth to digitize geological data for global access. Through these efforts, IUGS plays a vital role in bridging national geological communities and addressing societal needs, from to .

History

Foundation

The International Geological Congress (IGC), initiated in 1878 in , , served as the primary precursor to the International Union of Geological Sciences (IUGS), providing a vital platform for geoscientists worldwide to collaborate on key issues such as standardizing geological terminology, correlating stratigraphic units globally, and advancing international mapping initiatives. Held quadrennially, the IGC fostered exchanges among hundreds of delegates from diverse nations, laying the groundwork for sustained international cooperation in the earth sciences despite interruptions from global conflicts, including . By the mid-20th century, the need for a more permanent organizational structure to coordinate these efforts beyond periodic congresses had become evident, particularly as geological research increasingly intersected with interdisciplinary fields like and . The formal founding of the IUGS occurred during the 21st IGC in , , in August 1960, where delegates approved the union's statutes and resolved to establish a dedicated body to oversee ongoing geological collaboration. This decision culminated in the official incorporation of the IUGS on March 2–3, 1961, at in , as a non-governmental organization affiliated with the International Council of Scientific Unions (now the ). Registered as a nonprofit entity , the new union assumed sponsorship of the IGC and aimed to institutionalize the congress's legacy while addressing the growing demands of postwar scientific advancement. The initial objectives of the IUGS centered on promoting international cooperation in geological studies, particularly those of global significance, standardizing nomenclature and methodologies, and integrating earth sciences with related disciplines to support human welfare and . These goals reflected a commitment to enhancing understanding of Earth's processes and history through collaborative , , and policy influence. James M. Harrison, a Canadian , was elected as the first president (1961–1964), guiding the union through its formative years amid the challenges of rebuilding global scientific networks fractured by and emerging geopolitical tensions, which initially limited participation from some nations and constrained funding.

Key Milestones and Evolution

Following its establishment in 1961, the International Union of Geological Sciences (IUGS) experienced steady growth in membership, expanding from an initial group of national adhering bodies to 121 by 2023, thereby representing over 1 million geoscientists worldwide. This expansion reflected the Union's increasing global reach and its role in fostering international collaboration in Earth sciences. A significant organizational shift occurred in 2012 when the IUGS Secretariat relocated from the to the Chinese Academy of Geological Sciences in , enhancing geographical balance and representation from and developing regions. This move supported broader engagement with diverse member countries and strengthened administrative efficiency. In 2018, the IUGS transitioned its affiliation from the (ICSU) to the newly formed (ISC), maintaining its status as a key member organization dedicated to advancing global scientific cooperation. The Union's 50th anniversary in was marked by a commemorative event at in , which highlighted its achievements and introduced initiatives to recognize contributions through legacy programs and awards. Similarly, the 60th anniversary in 2021—primarily celebrated in with events extending from —emphasized heritage preservation, culminating in the designation of the first 100 IUGS Geological Heritage Sites to promote sites of international scientific significance. Recent adaptations included responses to the , such as multiple postponements of the 36th International Geological Congress, which was ultimately held in a virtual format on March 20-22, 2022, ensuring continuity of scientific exchange amid global disruptions. In 2024, leadership transitioned to President Hassina Mouri for the 2024-2028 term, the first woman and African geoscientist in the role, signaling a commitment to diversity and inclusive governance. As of 2025, the IUGS continues nominations for Geo-Collections of Global Importance to safeguard key geological repositories, while addressing administrative challenges through the temporary suspension of its collaboration with the Deep-Time Digital Earth program, announced in April 2025 for one year.

Organization

Governance and Leadership

The International Union of Geological Sciences (IUGS) operates under a hierarchical structure designed to ensure democratic representation and efficient administration. The serves as the supreme governing body, comprising delegates nominated by adhering national , chairs of commissions, and members of the Executive Committee; it convenes every four years during sessions of the International Geological Congress (IGC) to oversee all major activities and set strategic policies. The Executive Committee (EC), elected by the , handles day-to-day operations and implements directives between Council meetings, consisting of the President, two Vice-Presidents, the Secretary General, the , and four Councillors. Elections for the President and the EC occur at ordinary Council sessions held during IGCs, with terms lasting four years; each active adhering member organization casts one vote for most decisions, though financial and IGC-hosting matters allow from one to eight votes based on membership category. As of 2025, the current leadership for the 2024-2028 term includes President Prof. Hassina Mouri from , Secretary General Dr. Ludwig Stroink from , Treasurer Emeritus Prof. David Cohen from , and Vice-Presidents Prof. Marko Komac from and Prof. Maria Rose Petrizzo from . The Secretariat, which supports operational functions under the Secretary General, is located in Beijing, , hosted by the Chinese Academy of Geological Sciences. The EC holds authority to approve annual budgets, new initiatives, and affiliations with , while the establishes overarching policies and long-term directions. Financially, IUGS is sustained primarily through annual dues from adhering member —scaled by financial contribution units adjusted periodically by the EC—along with grants from entities such as and proceeds from IGC events, which include negotiated shares of registration fees. As a U.S.-registered 501(c)(3) non-profit , IUGS maintains transparency through detailed annual financial reports that break down income, expenditures, and net positions, such as the 2023 report documenting total income of USD 705,163 and expenses of USD 745,070.

Membership and Affiliated Organizations

The International Union of Geological Sciences (IUGS) operates through adhering members, which are national or regional peak bodies such as geological societies, national academies of sciences, or geological surveys that represent the geoscientific community in their respective countries or regions. As of 2023, these adhering members encompass organizations from 121 countries and regions, enabling broad global representation in the Union's activities. Membership eligibility requires nomination by a recognized national or regional geoscience body, with final approval by the IUGS Executive Committee following review of the application and commitment to annual fees. Annual dues are structured in eight categories scaled from 1 to 8 units, determined by the economic capacity of the member country, often aligned with GDP indicators, to ensure accessibility across diverse economies. Adhering members enjoy several key benefits that enhance their role in international geoscience. These include voting rights in the IUGS for elections, strategic decisions, and selection of venues for the International Geological Congress (IGC); access to funding opportunities and educational resources such as publications and training programs; and active participation in the Union's commissions and working groups. Additionally, members gain representation at broader forums like the (ISC), fostering global collaboration and influence in geoscience policy. To promote inclusivity, particularly in developing regions, IUGS has intensified outreach efforts since 2023, including fee adjustments and targeted invitations to national bodies in underrepresented areas to expand membership and address geopolitical gaps in geoscientific engagement. Complementing the adhering members, IUGS maintains a network of 38 affiliated organizations, which are autonomous, international non-governmental scientific entities focused on specialized geoscience domains. These affiliates collaborate with IUGS on joint initiatives, scientific meetings, and exchange, enhancing the Union's reach without formal voting privileges. Notable examples include the (IAVCEI), which advances research. Affiliation is granted to organizations that align with IUGS objectives, following a review process by the Executive Committee to ensure mutual scientific benefits and alignment with global geoscience priorities.

Scientific Activities

Commissions and Working Groups

The International Union of Geological Sciences (IUGS) maintains seven active international commissions and several associated working groups and task groups, appointed for terms typically spanning four years to coordinate specialized research and foster global cooperation in the earth sciences. These bodies focus on advancing cooperative investigations, establishing international standards, and addressing emerging challenges in geological disciplines, with executives serving from 2020 to 2024 and transitions underway for the 2024-2028 period. Among the key commissions, the (ICS) plays a central role in standardizing the geological time scale through the ratification of Global Boundary Sections and Points (GSSPs) and updates to the International Chronostratigraphic . The ICS ratified five GSSPs between 2023 and 2024, including three in 2023 ( in , ; in , ; in , ) and two replacements (Aeronian and Telychian stages) in early 2024, with no further ratifications as of November 2025; updated versions of the were released in 2024, enhancing precision in history across and eras. The International Commission on Geoheritage (ICG) concentrates on identifying and preserving sites of exceptional geological value, culminating in the announcement of the Second 100 IUGS Geological Heritage Sites in August 2024 from 174 candidates across 64 countries. Other notable commissions include the , Training & Technology Transfer (COGE), which promotes global literacy through programs like the Geoscience Field Officers (GEFO); the and Application of Geoscience Information (CGI), which advances via standards like the Deep-time Digital (DDE) metadata edition released in 2023; the International Commission on the History of Geological Sciences (INHIGEO), documenting the evolution of geological thought; the Commission on Global Geochemical Baselines (CGGB), compiling worldwide geochemical datasets; and the and (TecTask), which supports research in deformational processes and is associated with the International Association for and (IASGT). The Commission on Geoethics (CG), established in 2023 to develop ethical guidelines for geoscientific practice, was disestablished in April 2025. Additional specialized bodies, such as the Initiative on Forensic Geology (IFG), apply geosciences to criminal investigations, while karst-related efforts are supported through affiliated collaborations. IUGS working groups and task groups, numbering around four primary active ones alongside numerous subcommissions, address targeted issues on shorter timelines, often 2-4 years, to support commission mandates. Examples include task groups under former CG on in Geosciences and Diversity, Equity, Inclusion, and Accessibility (DEIA), aimed at ethical AI applications and inclusive policies; the Resourcing initiative, focusing on sustainable and resource management for long-term societal needs; and subcommissions within ICS, such as those on and Permian Stratigraphy, alongside specialized groups on earth tides and under broader geophysical programs. These bodies produce coordinated projects, authoritative reports, and global standards that underpin research, such as ICS's chronostratigraphic updates and ICG's heritage evaluations, which inform policy and worldwide.
