European Commission – Horizon Europe open access policy
Horizon Europe (HEU) is the EU’s key funding programme for research and innovation launched in 2021. One of its aims, is increasing the current standard of dissemination of knowledge with a new open science policy by sharing research outputs, tools and data as soon as possible.
Open access policy for peer-reviewed scientific publications
Open access policy for monographsScientific publications - when must your research output be made open access?
All peer-reviewed scientific publications must be made open access at the latest at the time of publication via either green or gold open access. A machine-readable electronic copy of the published version (VoR) or the final peer-reviewed author accepted manuscript (AM), must be deposited in a trusted repository for scientific publications.
All publications must be deposited in a trusted repository (even the gold open access one!)
In addition, information about research underlying data, any other tools and instruments needed to validate the conclusions of the scientific publication must be made available in a repository on publication.
Licence requirement
CC-BY or a licence with equivalent rights for gold and green open access outputs. This means that AM deposited on a trusted repository must be immediately open access – i.e. embargo is not allowed.
How to make your research output open access
Gold open access
Only publication fees in full open access venues (e.g. fully open access journal as listed in DOAJ), for peer-reviewed scientific publications are eligible for reimbursement from the HEU grant.The University has agreements with many publishers that allow gold open access at no additional cost or at a discount.
Open Research Europe (ORE) platform: this an open access platform providing fast publication and open peer review for research stemming from Horizon 2020 and Horizon Europe funding across all subject areas. This has no publishing fees. If ORE is selected as the publishing venue, all open access to scientific publication requirements will be fulfilled by the beneficiary.
Green open access
Author can publish in a hybrid or closed (subscription) venue, as long as immediate open access is provided to the deposited AM via the trusted repository at the same time as publication, under CC BY or a licence with equivalent rights.Apply the Rights Retention Statement to all submissions to ensure that you retain copyright to the accepted manuscript.
It is researchers’ responsibility to select a journal that complies with HEU self-archiving requirements. Please contact openaccess@abdn.ac.uk or use the PlanS Journal Checker Tool to confirm whether a journal is compliant before submitting your manuscript.
Trusted repositories are disciplinary and domain repositories commonly used and endorsed by the research communities and recognised internationally.
Recommended repositories that meet HEU criteria are:
- Europe PMC for life sciences including biomedicine and health
- arXiv for physics, mathematics, computer science, quantitative biology, quantitative finance and statistics
- the CLARIN-DK-UCPH Repository for digital language data
- the European Nucleotide Archive
- the European Southern Observatory databases of astronomical observations
- Zenodo, general purpose and used by Open Research Europe.
We strongly advise to also upload your accepted manuscript to the University of Aberdeen repository AURA. Once your research output is accepted, send an email to paperaccepted@abdn.ac.uk with a copy of your AAM and the acceptance email, and the open access team will upload your manuscript on the repository on your behalf.
Open access requirements for data
Researchers funded by HEU are required to establish a data management plan (DMP), and regularly update it.
Researchers must:- deposit the data in a trusted repository; if required in the call conditions, this repository must be federated in the European Open Science Cloud (EOSC) in compliance with EOSC requirements
- ensure open access as soon as possible and within the deadlines set out in the DMP to the deposited data via the repository, under the latest available version of the Creative Commons License (CC BY) or Creative Commons Public Domain Dedication (CC 0) or a licence with equivalent rights.
- provide information via the repository about any research output or any other tools and instruments needed to re-use or validate the data.
If open access is not provided (to some or all data), this must be justified in the DMP.
Monographs - When must your monograph be made open access?
The beneficiary must provide immediate open access upon publication through either gold (published version (VoR) is open access) or green (the author accepted manuscript (AAM) is deposited on a trusted repository and made available open access on publication date) route.
Licence requirement
CC BY-NC or CC BY-ND for VOR and AAM.
How to make your research output open access
Gold open access
If the venue meets the open access criteria, then the publication fees (including open access fees) can be reimbursed from the Horizon Europe grant. The publishing fees for open access monographs will cover the first digital open access edition of the book (which could include different formats such as html, pdf, epub, etc). Printing fees for the monographs and other books are not eligible.
Green open access
The publication fees would have to be covered by other funds and the beneficiary will still have to deposit an AAM or VOR under a CC BY-NC or CC BY-ND licence in a trusted repository at the same time as publication (no embargo period allowed).
The repository needs to not only provide open access to the deposited monograph, but also support the metadata of the deposited monograph in the repository, under a CC 0 public domain dedication. Such repositories should be recognised internationally.
The OAPEN Open Books library is likely to fulfil the requirements of a trusted repository, however, the OAPEN website has not currently been updated to take into account the open access changes under Horizon Europe.

Licence requirement
CC-BY preferred for either gold or green research outputs, but not mandatory, other Creative Commons licenses are accepted.
How to make your research output open access
Article processing charges (APC) for gold open access publications in fully open access and hybrid journals are eligible for reimbursement during the duration of the project. The costs of 'gold' open access publications incurred once a project is completed cannot be refunded from that project's budget. Gold open access publication must be deposited in a repository of authors’ choice (see below).
The University also has several agreements with publishers that allow gold open access at no additional cost or at a discount.
Apply the Rights Retention Statement to all submissions to ensure that you retain copyright to the accepted manuscript.
The Accepted Manuscript must be deposited in the institutional or other repository with an embargo limit of 6 months for STEM subjects and 12 months for publications in the social sciences and humanities.
To provide support concerning compliance with Horizon 2020 embargo periods the Commission offers a model amendment to publishing agreements, which are often signed between authors and publishers.
Embargo exception: green open access with a longer embargo period is accepted for publications issued after the end of the funded project, if open access within the maximum acceptable embargo period cannot be provided without incurring in additional costs for gold open access.

All papers must include details of the funding that supported the research and a statement explaining how other researchers can access any data, original software or materials underpinning the research (Wellcome’s data, software and materials management and sharing policy).
Researchers and organisations who do not comply with Wellcome open access policy might not be allowed to submit new grant applications. In extreme cases, current funds might be suspended.
When must your research output be made open access?
All original research articles must be made freely available via PubMed Central and Europe PubMed Central by the official final publication date.
Where there is a significant public health benefit to preprints being shared widely and rapidly, such as a disease outbreak, Wellcome requires the posting of preprints under CC BY licence.
Licence requirement
CC-BY for all outputs. CC-BY-ND licence is allowed if explicitly agreed with Wellcome Trust. The form on this page Wellcome Trust Applying for a No-Derivatives Licence can be used to request such exception.
How to make your research output open access
There are three routes to open access for Wellcome funded research. Routes 1 and 2 are preferred but where these are not possible route 3 will provide an alternative route to compliance with the open access policy.
Route 1
Publish in a fully OA journal or platform. Using this route, the publisher takes responsibility for making the Version of Record for the article freely available from Europe PMC at the time of publication.
Wellcome provides a small block grant for publishing in fully open access journals or (until Dec 2024) transformative journals.
Route 2
Publish in a hybrid (subscription) journal through a transformative arrangement that is available to you via your organisation.
Under this route, the publisher takes responsibility for making the Version of Record for the articles freely available in Europe PMC at the time of publication, under a CC BY licence.
The Journal Checker Tool will let you know if a transformative arrangement for your preferred journal is available to you through your organisation.
Route 3
Publish in a hybrid (subscription) journal and take responsibility for making the Author Accepted Manuscript (AAM) freely available from Europe PMC at the time of publication under a CC-BY licence. Use the author manuscript submission system Europe PMC plus to deposit your AAM.
To grant a CC-BY licence for the author accepted manuscript, submissions of original research to peer-reviewed hybrid journals must include the following statement
‘This research was funded in whole, or in part, by the Wellcome Trust [Grant number]. For the purpose of Open Access, the author has applied a CC BY public copyright licence to any Author Accepted Manuscript version arising from this submission.'
Include the statement in:
- any cover letter that accompanies the submission
- the funding acknowledgement section of the manuscript.
If you are unable to make the Version of Record or the Author Accepted Manuscript open access, then you may post a preprint under a CC BY licence. Wellcome will accept this as compliant with the policy in these situations.
Please contact openresearch@abdn.ac.uk or use the Journal Checker Tool to confirm whether a journal is compliant before submitting your manuscript.
