General information

The EGU General Assembly provides a forum for scientists to present their work and discuss their ideas with colleagues in all disciplines of the Earth, planetary, and space sciences. The EGU strives for an open and constructive scientific exchange, based on mutual respect.

Please note that it is not permitted to take photographs or videos of any presentations (oral, poster, or PICO) unless explicit permission is granted by the author. More details are in the oral, PICO, and poster guidelines below, including download links for symbols encouraging or not allowing photography.

Abstract content and abstract submission

Abstracts of the work that is to be presented at the General Assembly should be short (100–500 words), clear, concise, and written in English with correct spelling and good sentence structure. Every abstract should present unique research. Submission of duplicate abstracts is considered unethical, irrespective of presentation format or programme group that an abstract is submitted to.

EGU abstracts remain online and are searchable also for people not participating in the General Assembly. All abstracts receive a DOI (digital object identifier). Abstracts (except withdrawn ones) are also indexed in the SAO/NASA Astrophysics Data System (ADS). They are not indexed in other bibliographic databases like Scopus. ORCID numbers will be linked to authors that have their ORCID included in the personal data section of their Copernicus account.

Further information on abstract submission can be found on how to submit an abstract.

One-abstract rule

Authors are allowed as first author to submit either one regular abstract plus one abstract solicited by a convener, or two solicited abstracts. A second regular abstract can be submitted to the Education and Outreach Sessions (EOS) programme group (the maximum number of abstracts, including solicited abstracts, remains two). Possible submissions for first authors are the following:

  • 1 regular + 1 solicited abstract;
  • or 2 solicited abstracts;
  • or 1 regular or solicited abstract + 1 EOS abstract (regular or solicited).

Since the system limits abstract submissions to one you will need to provide a transaction number (TAN) when submitting your additional solicited abstract. This TAN has to be provided by the convener. Participants can be co-author on additional abstracts in which they are not first author.

EGU membership required

Only EGU members are able to submit an abstract as first author. You can become member or renew your membership at the EGU webpage.

Abstract processing charges (APCs)

Please note that abstracts have an abstract processing charge (APC) of €40. Late contributions (uploaded by conveners after the abstract deadline) have an increased APC of €80 and require approval by the programme committee.


The EGU General Assembly facilitates the presentation of scientific results in the form of poster presentations, oral presentations, and PICOs. The EGU stresses that all scientific presentations at its General Assembly have equal importance, independent of format. There is no distinction regarding the standing, quality, or prestige of oral, poster, or PICO presentations. Please note that EGU does not provide templates for the compilation of oral presentations, printed posters, or PICO presentations.

General presentation tips

  1. Use font sizes that are large enough to be read from some distance.
  2. Avoid the rainbow colour scale or the parallel usage of green and red since it is not distinguishable for everyone. For a list of colour scales that are illegible to a significant number of readers, please visit ColorBrewer 2.0.
  3. Place EGU's official graphic whether you forbid or allow photography of your presentation: photography encouraged | photography NOT allowed.
  4. Ensure that all images in presentations are attributed, including those from Wikipedia.
  5. If presentations include maps, authors are asked to adhere to United Nations naming conventions. In order to depoliticize scientific presentations, authors should avoid the drawing of borders or use of contested topographical names.
  6. Consider adding a QR code to the author's website or a website with further information.

Please respect the following presentation guidelines and rules

  1. Authors (first and co-authors) cannot have a solicited presentation in a session they (co-)convene.
  2. (Co-)conveners cannot be presenting author, and are discouraged from being co-author, on oral presentations in a session they convene.
  3. Acceptance of an abstract and its inclusion in the programme of the General Assembly obliges the author or one of the co-authors to present the contribution at the time and in the manner indicated. If you know that your presentation will not be presented, you are asked to withdraw your abstract as soon as possible.
  4. At the conference, missing presentations are categorized as no-shows if the abstract has not been withdrawn by the time of the presentation as given in the programme. Such no-shows will be recorded and conveners will be informed after the conference. No-show authors will be asked for reasons. Without appropriate reasons, these abstracts will be removed from the conference website and a message "withdrawn after no-show" is added to the presentation slot in the online programme.
