The 26th Klimatag will take place from Wednesday, 8 April 2026 to Friday, 10 April 2026 at the University of Vienna Biology Building of the University of Vienna.
The conference will be held in German. Presentations in the scientific sessions as well as poster talks during coffee and lunch breaks can, if needed, be given in English. Please let us know at klimatag@ccca.ac.at if you'd like to give your presentation in English. We need this information for the briefing of the session chairs.
In addition, the ACRP quality assurance session will be held entirely in English.
The call for abstracts for the 26th Klimatag has been closed since autumn 2025.
The call for abstracts for the general scientific sessions, the ACRP quality assurance for 2027, and for the CCCA Early Career Award is expected to open in autumn 2026. Sign up for the CCCA Newsletter so you don't miss out!
The Austrian Klimatag places a particular focus on cooperation and dialogue with stakeholders from policy, public administration, and research funding. In addition to serving as an interdisciplinary networking event for the climate research community, the Klimatag also facilitates exchange with business representatives, practitioners, and the interested public.
The Klimatag is organised according to the Green Meeting criteria of the Austrian Ecolabel, thereby meeting the highest environmental standards. The many efforts include climate-friendly catering, offsetting of resulting CO2 emissions, and avoiding printed materials. You can support our efforts by choosing low-emission modes of transport for your journey, such as train, bus, or carpooling. Further information on the Green Meeting can be found here.
Yes, photos and/or videos of participants will be taken during the Klimatag for documentation purposes. If you have any feedback or questions about this, please get in touch with us at klimatag@ccca.ac.at.
Registration will open shortly and is open until Thursday, 19 March 2026 (2 pm). Please register within this period so that we can prepare the conference materials in good time before the Easter holidays. Click here to register.
Please note: cancellations with full reimbursement are possible until Thursday, 26 March 2026, 2 pm by emailing klimatag@ccca.ac.at. After this date, the participation fee will be charged. Thank you for your understanding!
Yes, presenters and speakers are also asked to register for the Klimatag via the online portal.
The Klimatag has grown into CCCA's central networking event and is very well attended. Networking and exchange in a relaxed atmosphere are a key aspect, and we want to make sure the catering is up to scratch too. However, this does require adequate funding to ensure the right level of quality. We therefore charge a participation fee of €140 for attending the Klimatag 2026. A reduced fee of €90 applies for students.
You can find the programme here.
The programme is subject to change, as it is continuously being updated for you.
Each session is moderated by a session chair, who is responsible for the thematic introduction, keeping to the schedule, and leading the discussion.
Each session typically features 3 to 5 specialist presentations. Scientific Sessions II and IV also include 2 additional flash talks. The allocation of contributions was carried out by the programme committee, which grouped the submitted topics into coherent thematic clusters.
After each presentation, or after every second flash talk, the audience has the opportunity to engage in professional exchange with the presenters through questions and comments.
Note: This year, the flash talk format has been introduced for the first time. A flash talk is a very short, concise presentation of a research project (04 minutes). Only the absolute highlights of the project should be presented. A classic structure of introduction, methodology, results, and discussion is explicitly not desired. The flash talk should provide a quick overview, spark interest, and encourage further exchange.
We'd like to point out that participants at the Klimatag come from various disciplines. To make your presentation accessible to a broad audience, we've put together a summary slide. We ask you to include this slide at the beginning of your presentation to help ease attendees into the topic. The font size can be adjusted as needed. The slide has been sent to you by e-mail.
Presentations within the scientific sessions are allocated 10 minutes of speaking time and 5 minutes for discussion. Please stick to the time limits. Based on the maximum speaking time, we also recommend preparing no more than 10 slides per presentation. Please use 16:9 format for your slides. We'd also ask you to prepare your slides in the language of your presentation so the audience can follow along more easily.
Additionally, during submission we asked you to tick the SDGs that are addressed in your research project. We ask you to also make the SDGs visible on your presentation slides. The icons for the respective SDGs have been sent to you by e-mail.
The preferred language for the scientific sessions is German; however, presentations can also be given in English if needed. Please let us know by the time you submit your presentation slides at the latest.
The presentation slides will be made publicly available on our website after the Klimatag has taken place, provided we have received approval from the presenters. You'll find them under the Programme tab, within the respective session.
Contributions for the "general scientific sessions" went through the Klimatag review process and were assessed by at least 2 suitably qualified reviewers. The Klimatag programme committee compiled the Klimatag programme on the basis of the reviewers' evaluations.
The Flash Talks take place in two of the five scientific sessions, namely in Session II and Session IV.
Each scientific session is moderated by a session chair, who is responsible for the thematic introduction, keeping to the schedule, and leading the discussion.
Each session typically includes 3 to 5 specialist presentations. Sessions II and IV additionally feature 1 to 2 complementary Flash Talks. The assignment of contributions was carried out by the programme committee, which grouped the submitted topics into coherent thematic clusters.

After the conference, you'll have the opportunity to make the slides from your talk viewable on the Klimatag website.
The ACRP Sessions will be held in English. Please design your talk accordingly in English. Please also design your poster in English.
In the "general scientific sessions", researchers from all subject areas and disciplines with connections to the topic of climate change and transformation have the opportunity to submit talks and poster contributions for presentation at the Klimatag. These contributions are reviewed, as has been the practice in previous years, by thematically appropriate reviewers and the Klimatag Programme Committee.
The ACRP Sessions are where the annual quality assurance for the Austrian Climate Research Programme takes place. Selected ACRP projects present to the ACRP Steering Committee. The ACRP project leaders whose projects are affected have been separately invited by the Climate and Energy Fund to present their project at the Klimatag.
The posters will be assigned to one of the scientific sessions by theme and will also be briefly introduced by the session chairs within that session.
In addition, the well-known Poster Talks (formerly Poster Sessions) will take place during the coffee and lunch breaks. At these Poster Talks, interested participants can ask questions about your poster. There are designated time slots for this, so that you can also enjoy the breaks and have a look at other posters.
