What Is the EGU General Assembly?
The EGU General Assembly is an international scientific meeting organised by the European Geosciences Union. It brings together geoscientists from around the world to present research, discuss emerging scientific questions and develop collaborations.
The assembly covers a broad range of disciplines within:
- Earth sciences
- Planetary sciences
- Space sciences
- Climate and atmospheric research
- Ocean sciences
- Hydrology
- Geophysics
- Geology
- Environmental geosciences
- Natural hazards
- Geoscience education and communication
- Geoscience and society
EGU27 is designed as an interactive forum where scientists—particularly early-career researchers—can present their work and discuss ideas with experts from different geoscience fields.
Where and How Will EGU27 Take Place?
EGU27 will use a combined participation model.
On-Site Participation in Vienna
Researchers can attend in person at the Austria Center Vienna. On-site participation provides opportunities for face-to-face presentations, discussions, networking and collaboration.
Virtual Participation
Researchers unable or preferring not to travel can participate online. During abstract submission, authors must indicate whether they plan to present on-site in Vienna or virtually.
Perth Regional Hub
For EGU27, the organisers will also trial a Regional Hub in Perth, Australia. This initiative is intended to explore broader international participation without requiring every participant to travel to Vienna, while supporting local networking and keeping attendees connected with the Vienna meeting.
Authors considering this route should check the specific Regional Hub instructions before selecting their presentation arrangements.
Who Should Submit an Abstract to EGU27?
EGU27 may be relevant for:
- PhD candidates
- Postdoctoral researchers
- Early-career scientists
- University academics
- Research-institute scientists
- Undergraduate and master’s students with suitable research
- Environmental and Earth-science professionals
- Planetary and space-science researchers
- Researchers working on interdisciplinary geoscience topics
Submitting an abstract can provide an opportunity to:
- Present original research to an international audience
- Receive feedback from specialists
- Discuss preliminary or completed findings
- Develop collaborations
- Learn about related research
- Increase the visibility of your work
- Build your academic presentation experience
An abstract submission does not guarantee acceptance or a particular presentation format. Session organisers review contributions and arrange the scientific programme.

EGU27 Abstract Requirements
Before submitting, make sure your abstract complies with the official rules.
Abstract Length and Language
The abstract body must:
- Contain 100–500 words
- Be written in English
- Be clear and concise
- Use correct spelling and sentence structure
- Describe original research
- Include only genuine contributors as authors
Mathematical symbols and equations may be typed into the submission form or embedded as images.
Originality
The submitted abstract must be original and must not have been presented at a previous EGU General Assembly.
The same abstract must not be submitted to more than one session. Duplicate submissions can be rejected.
Presentation Responsibility
Submitting an abstract carries the obligation that it will be presented by the author or at least one co-author.
If nobody can present the research, the abstract should be withdrawn as early as possible. Abstracts that are not presented without early withdrawal may be marked as no-shows and removed from availability in the online programme.
Responsible Use of AI Tools
The official EGU27 guidelines state that AI tools must not be used to create the substantive content of the abstract. This restriction does not refer to using AI tools for language editing or proofreading.
Authors remain responsible for the scientific content, originality, authorship and accuracy of their submissions.
EGU Membership Requirement for First Authors
All first authors submitting an abstract to EGU27 must be:
- A 2027 EGU member, or
- An honorary or life member
Membership can be obtained during abstract submission or in advance through the EGU membership system.
If you arrange membership before submitting, use the same user account for your membership and abstract submission. A co-author cannot purchase the required membership on behalf of the first author.
EGU membership also provides reduced conference registration rates.
EGU27 One-Abstract Rule
Authors are generally limited to one regular abstract as first author, although specific exceptions exist.
Permitted combinations can include:
- One regular abstract and one solicited abstract
- Two solicited abstracts
- An additional permitted submission involving a Geoscience & Society-led session
- Certain submissions involving the Perth Regional Hub session
The maximum remains two abstracts under the permitted combinations. Depending on the submission type, a transaction number from a convener may be required.
Because the exceptions are specific, consult the official one-abstract rule before attempting a second submission.
Presentation Formats at EGU27
Depending on the session, contributions may be presented as:
- Oral presentations
- Poster presentations
- PICO presentations
During submission, you will be asked to indicate your presentation preference. Some sessions are specifically organised around PICO presentations, in which case that format is already selected.
You must also indicate whether you intend to present:
- On-site in Vienna
- Virtually
The final presentation assignment depends on the session organisers and scientific programme.
How to Submit an Abstract for EGU27
Follow these steps carefully.
Step 1: Prepare Your Abstract
Use a text editor to prepare:
- Abstract title
- Complete author list
- Author affiliations
- Abstract body of 100–500 words
- Relevant equations or symbols, if necessary
Check the scientific content, author names and affiliations before entering the submission system.
Step 2: Find the Most Relevant Session
Browse the EGU27 session programme or use the website’s search function.
Do not choose a session only because its title contains one general keyword. Read the complete session description and consider whether your research addresses its scientific objectives.
Step 3: Use the Submission Link for Your Chosen Session
Each session provides access to the abstract-submission process. Do not submit the same abstract to multiple sessions.
If you accidentally choose the wrong session, contact egu27@copernicus.org rather than withdrawing and resubmitting. The official guidance warns that processing charges for abstracts withdrawn because of an incorrect session selection are not refunded.
Step 4: Log In to the Copernicus System
Use your existing Copernicus account if you already have one. First-time users must create an account.
Adding your ORCID to your Copernicus personal information allows it to be linked with the relevant author details.
Step 5: Confirm Your 2027 EGU Membership
First authors must have the appropriate 2027 membership. Arrange it beforehand or complete the membership process during submission.
Step 6: Enter the Abstract Information
Complete the required fields, including:
- Title
- Authors
- Affiliations
- Abstract body
- Presentation preference
- On-site or virtual participation choice
- Invoice information
Step 7: Review the Abstract Preview
Carefully check:
- Spelling and grammar
- Scientific accuracy
- Author order
- Author affiliations
- Selected session
- Presentation preference
- Participation format
Step 8: Accept the Required Agreements
Authors must accept the applicable licence and copyright agreement and the General Assembly rules of conduct.
Step 9: Pay the Required Charges
Pay the Abstract Processing Charge and, if applicable, the 2027 EGU membership charge. Separate invoices may be issued.
Step 10: Save Your Confirmation
After submission, you should receive an abstract number and confirmation email.
If the confirmation email does not arrive within 24 hours, check your spam folder before contacting the organisers.
Official instructions are available on the EGU27 abstract-submission page.
EGU27 Abstract Processing Charge
The regular Abstract Processing Charge is €50 gross per abstract.
Important conditions include:
- Payment is required before the abstract is processed and made available to conveners.
- The charge is a processing fee, not a publishing fee.
- It is separate from conference registration.
- It is generally non-refundable following withdrawal, rejection or duplicate submission.
- Submitting an abstract does not register you for the conference.
Approved emergency abstracts uploaded by conveners after the regular deadline carry a higher charge of €95 gross.
EGU27 Registration Fees
Authors must complete conference registration separately from abstract submission.
The following are the published early week-ticket rates, available by 1 March 2027 at 13:00 CET:
| Participant category | On-site early rate, gross | Virtual early rate, net |

Full eligibility and application instructions are available on the EGU27 financial-support page.
Tips for Writing a Strong EGU27 Abstract
Start With the Scientific Problem
Explain the research question or knowledge gap clearly. Readers should understand why the study matters within its field.
Describe Your Methods Briefly
Provide enough methodological information for reviewers to understand how the research was conducted. Avoid excessive technical detail that leaves insufficient space for results.
Include Actual Findings
Where possible, present specific results rather than only stating that results “will be discussed.” Quantitative findings, observed patterns or clearly explained qualitative outcomes can strengthen the abstract.
Explain the Significance
Conclude by explaining what your findings contribute to the field and why they are relevant to the chosen session.
Match the Session Carefully
A strong abstract submitted to an unsuitable session may not receive the right audience. Use the session description and keywords to assess fit.
Check Authorship Carefully
Confirm that every listed author has contributed appropriately and agreed to the submission. Verify names, affiliations and author order before submitting.
Edit Without Changing Scientific Responsibility
Careful proofreading is essential. Follow EGU’s rules concerning AI tools and ensure that the substantive scientific content remains the authors’ own work.
