The European Geosciences Union (EGU) is the leading organization for Earth, planetary and space science research in Europe. With our partner organizations worldwide, we foster fundamental geoscience research, alongside applied research that addresses key societal and environmental challenges. Our vision is to realise a sustainable and just future for humanity and for the planet.

The EGU is a non-profit international union of scientists with about 20,000 members from all over the world. Membership is open to individuals who are professionally engaged in or associated with geosciences and planetary and space sciences and related studies, including students and retired seniors.

The EGU publishes a number of diverse scientific journals, which use an innovative open access format, and organizes topical meetings, and education and outreach activities. It also honours scientists with a number of awards and medals. The annual EGU General Assembly is the largest and most prominent European geosciences event, attracting over 21,000 scientists from all over the world in the year 2025. The meeting’s sessions cover a wide range of topics, including: natural hazards; planetary exploration; the Earth’s internal structure; atmosphere, hydrology, and biogeosciences; climate science; ocean science; as well as energy and resources.

The EGU was established in September 2002 as a merger of the European Geophysical Society (EGS) and the European Union of Geosciences (EUG), and has headquarters in Munich, Germany.

To deliver the EGU annual General Assembly we work in partnership with our conference provider and publisher, Copernicus.org.
