The European Geosciences Union (EGU) is a non-profit international union in the fields of Earth, planetary, and space sciences whose vision is to "realise a sustainable and just future for humanity and for the planet." The organisation has headquarters in Munich (Germany). Membership is open to individuals who are professionally engaged in or associated with these fields and related studies, including students and retired seniors. The EGU publishes 18 open-access scientific journals and a number of other science publications. It also organises a number of topical meetings, as well as education and outreach activities. Its most prominent event is the EGU General Assembly, an annual conference that brings together over 15,000 scientists from all over the world. The meeting's sessions cover a wide range of topics, including volcanology, planetary exploration, the Earth's internal structure and atmosphere, climate change, and renewable energies. The EGU has 22 scientific divisions that reflect the interdisciplinary nature of the organisation. History The EGU was established by the merger of the European Geophysical Society (EGS) and the European Union of Geosciences (EUG) on 7 September 2002. Council members of the two organisations came together at Hotel Platzl in Munich, Germany, to sign the Union into existence. The final stages of the merger were completed on 31 December 2003. The EGU founding members were: Jan Backman, Jonathan Bamber, Ray Bates, Günter Blöschl, Lars Clemmensen, Max Coleman, Peter Fabian, Gerald Ganssen, Jean-Pierre Gattuso, David Gee, Fausto Guzzetti, Albrecht Hofmann, Jürgen Kurths, Yves Langevin, John Ludden, Arne Richter, Michael Rycroft, W. Schlager, Roland Schlich, Isabella Premovi Silva, Christopher Spotl, Håkan Svedhem, Hans Thybo, Bert Vermeersen, David Webb, Jerzy Weber, Richard Worden. On 12 February 2004, the EGU signed the Berlin Declaration on Open Access to Knowledge in the Sciences and Humanities. The EGU Executive Office moved to central Munich on 1 August 2010, and later expanded by hiring six more staff members in addition to the EGU Executive Secretary, Philippe Courtial. In August 2011, the EGU signed an agreement with the American Geophysical Union (AGU) and with the Asia Oceania Geosciences Society (AOGS) with the aim to promote the cooperation between the institutions. In June 2019, the EGU announced a new chapter in its history: the Union launched a new strategy and moved its Executive Office to new premises in the Berg am Laim area of Munich. Conferences and meetings The European Geosciences Union convenes a yearly General Assembly.
