Horizon Europe CL5, climate, energy, transport: planned calls and infoday (6/5/2025)

The programme Horizon Europe, part Cluster 5: Climate, Energy and Mobility (CL5) prepares announcement of topics for international projects to be funded in 2025.

NEW: The European Commission has officially preliminarily published the texts of topics to be supported. Calls are planned to open in mid-May 2025. Source.

► On 30. 4. 2025, a Czech national infoday on these calls is organised. Event webpage and registration (in Czech).
► On 6. 5. 2025, the European Commission organise information day on these calls. Event webpage.

The information in this news is based on unofficial sources, the calls are still subject to change. Source.

If you plan to participate in a proposal submitted to a Horizon Europe call, please, contact well in advance the Project Management Department (Martina Holíková, martina.holikova@natur.cuni.cz).
See also Horizon Europe – practical information on faculty website.

If you are interested in one of the topics, but you don’t know, how to find a project coordinator or partners, please, contact the Project Management Department and we’ll recommend to you some networking opportunities.

If you have international research contacts and your research can be potentially used in applied research and in innovation, but cannot find a suitable topic in Horizon Europe, contact us and we can try to find a topic for you.

• CL5 calls on Funding & Tenders Portal – links to pages of the individual topics will be published here (a topic page includes i.a. basic information, topic description, links to relevant documents, frequently asked questions, interface for proposal submission.)
• Leaked draft Work Programme 2025: Climate, Energy and Mobility (source) Draft Work Programme 2025: Climate, Energy and Mobility – context and goals, description of all topics, budget information etc.
• About CL5 by European Commission.
• About CL5 by Czech National Contact Points – news, events etc.

Projects are carried out by international consortia with significant participation of users of results of the projects, the usual consortia size is ca. 8–25 entities (depending on scope of the topic) from EU countries or countries associated to Horizon Europe. Each project proposal must focus on one of the specific topics prescribed by the programme for the given year. About this type of projects on faculty website

CL5 contains topics potentially relevant for researchers in who’s research results can be used in the fields of e.g., climate change Earth system modelling, energy (batteries development, biofuels, geothermal energy, underground energy storage, impact on biodiversity, energy communities), CO2 capture, transport (including some societal aspects).

Examples of topics that seem relevant for the Faculty of Science:
If a topic title sounds relevant for you, read its full description, especially from the Expected Outcome a Scope, in the Work Programme (official draft).
