  • Horizon Europe Open Access Policy: Gold vs Green

    Under Horizon Europe, gold open access lets grantees claim Article Processing Charges (APCs) as an eligible cost when publishing in a fully open access journal, while green open access requires no APC but demands immediate deposit of the accepted manuscript in a repository — Horizon Europe permits no embargo period on either route. The route chosen changes what a grant can reimburse, not whether the underlying obligation to provide open access is met.

    Horizon Europe open access policy is the European Commission’s mandate, set out in the Horizon Europe Model Grant Agreement, requiring immediate open access to peer-reviewed publications arising from EU-funded research, with no embargo and a Creative Commons Attribution (CC BY) licence as the default. This article resolves the specific pre-award question research administrators and principal investigators raise most often: which route — gold or green — is cheaper, faster to budget, and lower-risk to comply with.

    What does the gold open access route require and cost?

    Gold open access means publishing the final version of record directly in a journal or platform that is open access from the moment of publication. Under Horizon Europe, APCs for publishing in a fully open access journal are an eligible cost and can be charged to the grant budget, provided the journal is genuinely open access rather than a subscription title offering a paid open option.

    The European Commission’s Horizon Europe Annotated Grant Agreement draws a firm line here: APCs paid to hybrid journals — subscription journals that unlock a single article for a fee — are not an eligible cost unless the journal is covered by an institutional transformative agreement the funder recognises. Grantees who publish gold must still deposit a copy of the final published version, and its metadata, in a trusted repository at the time of publication; paying the APC does not remove the deposit obligation.

    A cost-free variant of the gold route exists: Open Research Europe (ORE), the European Commission’s own peer-reviewed publishing platform for Horizon Europe and Euratom beneficiaries. ORE carries no APC for eligible authors, publishes under CC BY, and satisfies the immediate-access requirement without a grant budget line at all.

    What does the green open access route require, and is there really no embargo?

    Green open access means publishing as normal — including in subscription or hybrid journals — and separately depositing a copy of the work in a trusted repository so readers can access it without a subscription. Because no APC is typically paid, the green route carries no direct cost to reimburse, which is its main budgetary appeal.

    The compliance burden shifts instead to timing and rights. Horizon Europe’s Model Grant Agreement requires the author’s accepted manuscript (AAM) — the final peer-reviewed text before typesetting — to be deposited and made publicly accessible immediately on publication, with no embargo permitted. This is stricter than many national funder policies, several of which still allow embargoes of six to twelve months for the green route. Grantees must also apply a CC BY licence to the deposited manuscript, which means notifying the publisher of their funder obligations at submission, since standard subscription-journal copyright transfer agreements do not grant this right automatically.

    Retaining the necessary rights is the single most common green-route compliance failure. Institutions increasingly rely on rights-retention strategies — asserting a CC BY licence on the AAM ahead of acceptance — to avoid publisher pushback after the fact.

    Gold vs green: how APC reimbursement actually differs

    The financial and compliance trade-offs are distinct enough that they warrant a direct route-by-route comparison rather than treating “open access compliance” as one undifferentiated obligation.

    Factor Gold open access Green open access
    APC reimbursement Eligible for fully open access journals and platforms; must be budgeted in the grant Not applicable — no APC in most cases
    Hybrid-journal APCs Not eligible, unless covered by a recognised transformative agreement Not relevant — publish anywhere, then self-archive
    Embargo allowed Not applicable — immediate by definition None permitted under Horizon Europe
    Version deposited Final published version (Version of Record) Author’s Accepted Manuscript
    Licence required CC BY (CC BY-NC/ND permitted for monographs) CC BY on the deposited manuscript
    Zero-cost option Open Research Europe (no APC) Always zero-cost by design

    For grant budgeting, this comparison has one practical consequence: a grantee who assumes any APC is reimbursable, or that green deposit can wait for a standard embargo, will fall out of compliance. Horizon Europe’s no-embargo rule on green deposit is stricter than UKRI’s REF-era transitional allowances and than several national mandates still permitting embargoes — a distinction that trips up researchers moving from a previous funder’s rules onto a Horizon Europe grant.

    Common questions on Horizon Europe open access requirements

    What are the open access requirements for Horizon Europe?

    Horizon Europe requires all peer-reviewed scientific publications resulting from funded work to be made immediately open access, with no embargo, under a CC BY licence (or CC BY-NC/ND for monographs). This applies whether the grantee chooses the gold or green route, and a repository deposit is required in both cases.

    What is the European Commission’s open access policy under Horizon Europe?

    The Commission’s policy treats open access as the default expected outcome of publicly funded research, not an optional extra. It requires immediate access, open licensing, and open metadata, and extends beyond publications to FAIR research data underpinning them, governed by the grant’s Data Management Plan.

    Is open access always free for the author?

    No. Gold open access typically involves an APC, which Horizon Europe treats as an eligible grant cost only for fully open access venues. Green open access is generally free, since it relies on self-archiving rather than a publication fee, making it the lower-cost default where budget is constrained.

    What is an open access policy, in funder terms?

    An open access policy is a funder’s binding condition that research outputs be made freely accessible and reusable, typically specifying the timing (immediate vs embargoed), licence type, and eligible cost treatment. Horizon Europe’s version is among the strictest in Europe because it removes the embargo option entirely.

    What this means for grant budgeting and compliance teams

    Research offices preparing a Horizon Europe proposal should budget APCs only against fully open access venues or confirmed transformative agreements, and should not assume hybrid-journal costs will be reimbursed. Where budget certainty matters more than journal choice, green open access or Open Research Europe removes APC risk entirely while still meeting the immediate-access mandate.

    Compliance teams should build rights-retention language into author guidance before submission, not after acceptance, since the no-embargo rule leaves no room to negotiate access timing with a publisher post hoc. Institutional repository workflows that trigger deposit reminders at the point of acceptance — rather than publication — reduce the risk of missing the immediate-deposit requirement.

    As the European Commission continues to expand Open Research Europe’s remit and cOAlition S partners refine rights-retention model policies, the practical gap between the two routes is likely to narrow further on cost but remain wide on process — gold trades money for simplicity, green trades cost for rights-management discipline.

  • Horizon Europe Funded Projects: A CORDIS Guide

    Horizon Europe funded projects can be found and verified using CORDIS (the European Commission’s project and results database), the EU Funding & Tenders Portal, and the EU Open Data Portal. Together these three sources let research offices and journalists confirm a grantee’s funding claim, check participant lists, and pull bulk data for institutional funding intelligence — without relying on a press release alone.

    CORDIS is the European Commission’s public repository of information on all EU-supported research and innovation activities, covering Horizon Europe, Horizon 2020, and earlier framework programmes. Horizon Europe itself is the EU’s research and innovation programme running from 2021 to 2027 with a total budget of €95.5 billion — equivalent to more than £82 billion, per UK Research and Innovation (UKRI). For research administrators fielding a grantee’s funding claim, or journalists fact-checking a university press release, CORDIS and its companion open-data channels are the primary — and only authoritative — verification path.

    Table of Contents

    What Is CORDIS and How Does It Differ from the Funding & Tenders Portal?

    CORDIS (the Community Research and Development Information Service) is the European Commission’s archive of completed and ongoing EU-funded research, published once a project’s grant agreement is signed. It holds project factsheets, participant lists, publications, and results summaries. It is a record-of-outcome database, not a live application system.

    The EU Funding & Tenders Portal is the operational counterpart: it hosts open calls, submission tools, and — via its “Projects & Results” screen — a live, filterable list of funded projects that CORDIS later mirrors in fuller narrative form. Research offices verifying a fresh award should check the Portal first, since CORDIS records can lag a signed grant agreement by several weeks.

    • CORDIS — narrative factsheets, deliverables, publications, historical coverage back to earlier framework programmes.
    • Funding & Tenders Portal — live calls, submission status, the most current funded-project listings.
    • Horizon Dashboard — an analytical tool for exploring proposal and project statistics, success rates, and thematic breakdowns.

    Start at the CORDIS “Projects & results” search screen and filter by programme (“Horizon Europe”), then narrow by Call ID or Topic ID if you have one (for example, a Cluster 2 topic under the HORIZON-CL2 series). Country, funding scheme (RIA, IA, CSA, MSCA), and date-range filters further isolate a specific award.

    CORDIS also publishes curated “Results Packs” — thematic collections of projects grouped by policy area — which are useful for institutional landscaping rather than single-grant verification. For MSCA-specific searches, note that the 2026 MSCA Doctoral Networks call (reference HORIZON-MSCA-2026-DN-01-01) opened on 28 May 2026, per the UK Research Office (UKRO); calls of this kind appear on the Portal before a full CORDIS factsheet exists.

    Source Best for Data format Update cadence
    CORDIS Narrative verification, deliverables, publications Web factsheet, CSV/XML export Post-grant-signature, periodic refresh
    Funding & Tenders Portal Live calls, current award lists Web listing Continuous
    EU Open Data Portal Bulk download, cross-referencing, custom tools CSV, XML, RDF (Linked Open Data) Scheduled batch releases

    How to Verify a Horizon Europe Funding Claim

    To confirm a grantee’s claim, cross-check the project’s CORDIS factsheet against the institution named in the claim, the grant agreement number, and the coordinating organisation. A genuine Horizon Europe award will show a matching participant entry, a signed grant-agreement number, and a funding scheme code (RIA, IA, CSA, ERC, MSCA, or EIC) consistent with the claim.

    Research offices should treat three signals as minimum verification thresholds:

    • Grant agreement number matches the one cited in the press release or CV.
    • Participant organisation appears in the CORDIS or Portal participant list under the exact legal name, not an informal variant.
    • Funding scheme and call reference align with the programme claimed (for instance, an MSCA claim should carry an MSCA call ID, not a generic Horizon Europe label).

    Where a claim predates a public CORDIS factsheet, verification should fall back to the Funding & Tenders Portal’s live award listing, which the Commission updates continuously as grant agreements are signed.

    Open Data, APIs, and Bulk Downloads for Institutional Funding Intelligence

    For research offices building institutional funding intelligence rather than checking a single claim, the EU Open Data Portal offers bulk downloads of the entire CORDIS Horizon Europe dataset in CSV and XML. This supports local analysis, cross-referencing against institutional grant registers, and building custom compliance-tracking tools.

    CORDIS data is also published as Linked Open Data, allowing structured queries that connect project records to organisations, topics, and results. Registered users can access a CORDIS API for programmatic, automated retrieval — useful for offices that need to refresh a funding dashboard on a schedule rather than search manually. This combination of bulk export, Linked Open Data, and API access is the layer most institutional guides to horizon europe open calls and project tracking omit, yet it is the layer that turns one-off verification into a repeatable compliance workflow.

    Common Questions About Finding and Verifying Horizon Europe Projects

    What is CORDIS and is it the official source for Horizon Europe projects?

    CORDIS is the European Commission’s public database of EU-funded research and innovation activities, including Horizon Europe. It is the Commission’s own archive, making it the primary reference for confirming a project’s existence, participants, and funding scheme — more authoritative than a university press release or third-party aggregator.

    How do I search CORDIS for projects by topic, country, or call?

    Use the CORDIS “Projects & results” search page and apply filters for programme, country, funding scheme, and Call or Topic ID. Combining a Topic ID (such as a HORIZON-CL2 reference) with a date range narrows results to a specific call round quickly.

    How can I verify that a project claiming Horizon Europe funding is genuine?

    Cross-check the grant agreement number, coordinating organisation, and funding scheme code against the CORDIS factsheet or the Funding & Tenders Portal’s live listing. A mismatch on any of these three elements is grounds for further inquiry before repeating the claim institutionally.

    Can I download Horizon Europe project data in bulk?

    Yes. The EU Open Data Portal publishes the full CORDIS Horizon Europe dataset as CSV, XML, and Linked Open Data, and offers API access for registered users. This supports institutional dashboards, compliance sweeps, and cross-referencing against internal grant registers at scale.

    For research offices and journalists alike, the practical takeaway is the same: treat CORDIS and Portal listings as the verification baseline before any funding claim is repeated in an institutional profile, REF-style return, or news report, and use the Open Data Portal’s bulk exports when the task shifts from checking one grant to monitoring a whole portfolio. See CASRAI’s broader coverage of research administration practice for related compliance workflows.

  • Open Research Europe Impact Factor & Indexing

    Open Research Europe has no official Clarivate Journal Impact Factor (JIF), and by explicit policy it never will. The European Commission’s open-access publishing platform for Horizon Europe and Horizon 2020 beneficiaries deliberately rejects journal-level metrics in favour of article-level indicators, aligning itself with the DORA Declaration and the Leiden Manifesto.

    Open Research Europe (ORE) is a no-fee, open-access publishing platform launched in 2021 by the European Commission, built on F1000-derived publishing infrastructure, that carries Horizon Europe and Horizon 2020-funded research through an author-driven, post-publication open peer-review process. That structural choice — publish first, review openly afterwards — is precisely what makes the “impact factor” question harder to answer than a simple yes or no, and it is why ORE’s Scopus listing and its absence from Web of Science are so often confused with each other.

    Does Open Research Europe Have a Journal Impact Factor?

    No. Open Research Europe has never held a Clarivate Journal Impact Factor and has stated it will not pursue one. The COST-ORE webinar Question and Answer document is unambiguous on this point: “Open Research Europe does not have an Impact Factor (IF) and will not have one in the future.” This is a design decision, not a shortfall — ORE is structured around article-level metrics rather than a single journal-wide citation average.

    Some third-party indexing directories nonetheless display a figure they label an “impact score” or “Impact IF” for ORE, often citing a value around 1.4–1.9. These figures are not the Clarivate JIF. They are derived from Scopus citation data by commercial indexing-metrics sites, and they should not be quoted on a CV or grant application as a Journal Impact Factor, because no such official figure exists for ORE.

    What Does Scopus Indexing Mean for ORE Articles?

    Scopus indexing means an ORE article has cleared enough of a quality bar — completed open peer review, stable versioning, sustained publication activity — to be catalogued in Elsevier’s abstract-and-citation database. Per LIBER Europe’s ORE FAQ, articles are included in Google Scholar immediately on publication, but are only picked up by Scopus and Inspec once they pass peer review.

    Scopus coverage delivers three concrete benefits for authors:

    • Discoverability — articles surface in the citation searches institutions and publishers run by default.
    • Evaluator recognition — many national assessment exercises and promotion committees treat Scopus coverage as a baseline quality signal.
    • Citation tracking — Scopus data feeds the SCImago Journal Rank (SJR), the metric ORE actually reports in place of a JIF.

    According to SCImago Journal & Country Rank (data as of March 2026), ORE sits in the Q2 quartile of the Multidisciplinary category for 2023, 2024 and 2025, with an SJR of 0.391 in 2025 — up from 0.280 in 2023.

    Is Open Research Europe Indexed in Web of Science?

    As of mid-2026, Open Research Europe is not indexed in Clarivate’s Web of Science (WoS) core collection, though WoS inclusion is a stated ambition for the platform. This matters directly for the impact-factor question, because Web of Science coverage is the prerequisite Clarivate requires before it will calculate a Journal Impact Factor for any title.

    In practice, this means ORE’s absence from WoS and its absence of a JIF are the same fact stated two ways: no WoS record, no JIF eligibility. Researchers who need WoS-indexed output for a specific funder or national assessment requirement should verify ORE’s current WoS status directly before submitting, since indexing applications are described by ORE itself as ongoing.

    Why Does Post-Publication Peer Review Complicate the Comparison?

    ORE publishes an article before formal peer review begins, then runs an open, invited, named-reviewer process afterwards — authors must nominate at least five potential reviewers and keep sourcing names until two reports are published. Each revision produces its own version with its own DOI, so a single ORE article can exist as multiple citable, indexable records.

    LIBER Europe’s FAQ flags a genuine downstream problem this creates for librarians and indexers: databases that ingest every version risk flagging near-duplicate records for removal, while databases that keep only the latest version may lose citation history from earlier versions. This versioning mechanic — not just the absence of a JIF — is a structural reason why ORE resists being scored on the same axis as a conventional subscription or hybrid journal.

    How ORE’s Citation Data Compares, Year by Year

    Article-level growth is the metric ORE wants evaluated, and the underlying Scopus-sourced data shows a platform still scaling rather than a mature, steady-state journal.

    Year Documents published SJR Total cites Cites per document
    2022 117 — 87 1.554
    2023 151 0.280 247 1.428
    2024 196 0.376 532 1.642
    2025 221 0.391 899 1.938

    Source: SCImago Journal & Country Rank, metrics based on Scopus data as of March 2026.

    One further data point exposes a common misreading. SCImago’s Journal Value tool models an “estimated APC” for ORE of roughly $2,742 for 2025, calculated purely from its SJR and output volume. That figure is a statistical estimate, not a real charge: under LIBER Europe’s FAQ, ORE authors pay nothing, because the European Commission covers all publication costs directly for eligible Horizon Europe and Horizon 2020 beneficiaries. Treating the modelled APC as an actual fee is a documented source of confusion worth correcting explicitly.

    Common Questions About ORE’s Impact Factor and Indexing

    Does Open Research Europe Have an Official Impact Factor?

    No. Open Research Europe has confirmed it does not have, and will not seek, a Clarivate Journal Impact Factor. It reports article-level indicators — citations, views, downloads and reviewer reports — instead, consistent with the DORA Declaration and the Leiden Manifesto on responsible research assessment.

    What Is Open Research Europe?

    Open Research Europe is the European Commission’s open-access publishing platform for research funded under Horizon 2020, Horizon Europe and Euratom. It offers rapid, no-fee publication across 14 article types and six discipline areas, with an open, post-publication peer-review process.

    Is It Good to Publish in Open Access Platforms Like ORE?

    For eligible Horizon Europe and Horizon 2020 beneficiaries, ORE satisfies open-access and data-sharing mandates at no author cost while granting Scopus and Google Scholar discoverability. Researchers needing Web of Science-indexed output for a specific funder requirement should confirm current coverage before submitting.

    Implications for Authors, Institutions and Evaluators

    Research offices and evaluators should treat ORE’s metrics profile as a feature of the platform’s design, not a data gap to be filled in with an unofficial number. Institutional guidance to authors should explicitly state that quoting a scraped “impact score” for ORE on a grant application or CV is inaccurate, since no Clarivate JIF exists.

    Research administration teams responsible for tracking funder compliance and output reporting are better served citing ORE’s Scopus indexing status, SJR quartile and article-level citation counts — the same figures ORE itself publishes on every article’s dedicated metrics page.

    Outlook: What Happens Next

    The European Commission confirmed in a 26 March 2026 announcement that it is entering “a new era for Open Research Europe,” committing to continued funding for the platform and exploring its expansion to serve funders beyond the EU research programmes, potentially under a broader diamond open-access model with no author-facing fees. Whether that expansion brings a change to ORE’s metrics philosophy remains an open question, but nothing in the Commission’s public statements to date signals a reversal of the no-JIF policy. Institutions tracking ORE for compliance or assessment purposes should monitor the platform’s own indexing page directly, since Web of Science status and any future database applications are updated there as they are achieved.

  • Open Research Europe: 2026 Grantee Guide

    Open Research Europe (ORE) is the European Commission’s no-fee, open-access publishing platform for researchers funded under Horizon 2020, Horizon Europe and Euratom. It publishes articles first and peer-reviews them openly afterwards, which lets grantees satisfy the Horizon Europe open access mandate immediately, without an embargo or an article processing charge. From autumn 2026, operation of the platform moves to CERN and eligibility widens beyond European Commission-funded authors for the first time.

    Open Research Europe is an open-access publishing platform established in 2021 by the European Commission, built on a publish-review-curate model in which articles are made public before formal peer review begins.

    What is Open Research Europe?

    Open Research Europe is a dedicated, fee-free publishing venue for the outputs of EU-funded research. Articles go live shortly after an editorial pre-check for integrity and compliance, then undergo open, invited peer review — reviewer names, affiliations and reports are published alongside the work rather than kept confidential.

    The platform accepts 14 article types across six discipline areas, including research articles, data notes, method articles, software tool articles, and — distinctively — null and negative results, which conventional journals routinely decline. Each review round produces a separate, individually citable version with its own DOI.

    More than 1,200 articles from over 6,300 authors at more than 3,000 institutions worldwide had been published on ORE by March 2026, according to the European Commission’s Directorate-General for Research and Innovation (DG RTD).

    How does ORE satisfy the Horizon Europe open access mandate?

    Horizon Europe grant terms require beneficiaries to make peer-reviewed publications immediately open access, with no embargo period, under a CC-BY licence, and to manage underlying research data in line with FAIR principles. ORE is designed to meet all three requirements without extra administrative work by the author.

    • Immediate access: articles publish before peer review completes, so there is no embargo window to manage.
    • No cost barrier: the European Commission covers publication costs for eligible beneficiaries, removing the article processing charge (APC) that many gold open access journals require.
    • CC-BY licensing: published articles carry a Creative Commons Attribution licence by default, satisfying Horizon Europe’s reuse requirements.
    • FAIR data alignment: authors are expected to deposit supporting data in a trusted repository, and ORE’s open data policy is built around the FAIR (Findable, Accessible, Interoperable, Reusable) principles.

    Because the European Commission operates the eligibility and compliance checks centrally, a grantee publishing on ORE does not need to separately verify licence terms or embargo settings the way they would with a mixed portfolio of subscription and hybrid journals.

    Who can publish on ORE after the 2026 CERN transition?

    Today, ORE eligibility is tied strictly to funding: at least one contributing author must be part of a running or completed Horizon 2020, Horizon Europe or Euratom-funded project. That restriction is changing. In December 2025, the CERN Council approved CERN as the new hosting and operating organisation for ORE, and CERN will run the platform’s technical and administrative infrastructure from autumn 2026 onward.

    The new phase turns ORE from a single-funder platform into a consortium effort. A funding consortium of national research funders and organisations from Austria, France, Germany, Italy, the Netherlands, Norway, Portugal, Slovenia, Spain, Sweden and Switzerland joins the European Commission, which continues as a permanent observer and financial contributor. Governance sits with a Funders’ Group, supported by an Executive Committee and a Scientific Advisory Board (nominations for which opened 10 June 2026).

    Two operational details matter for grant administrators tracking this shift:

    • Since its 2021 launch, ORE has run on F1000’s open-research publishing infrastructure (part of Taylor & Francis); from autumn 2026 the platform moves to CERN-hosted infrastructure built on the open-source Open Journal Systems (OJS) software.
    • Publishing remains completely free of author-facing fees both for European Commission-funded researchers and for authors affiliated with institutions in the consortium’s participating countries — the current platform stays operational until autumn 2026 for ongoing submissions.

    ORE vs a traditional journal: when should grantees use which?

    ORE is the fastest, cheapest route to Horizon Europe open access compliance, but it is not a universal substitute for every publication decision. The table below sets out the practical differences a grantee should weigh before choosing a venue.

    Factor Open Research Europe Typical gold/hybrid journal
    Cost to author Free — covered by the EC or consortium funder APC often £1,500–£4,000+, or subscription paywall
    Peer review timing Open, after publication Closed, before publication
    Eligibility Horizon 2020/Europe/Euratom beneficiaries; widening to 11 consortium countries from autumn 2026 Open to any author who pays or has a qualifying subscription
    Article types accepted 14 types, incl. null/negative results, data notes, software tools Usually limited to research articles and reviews
    Indexing status Google Scholar on publication; Scopus and Inspec after peer review passes Varies by title; established journals often carry longer indexing history
    Impact metric No Journal Impact Factor; article-level metrics, DORA/Leiden Manifesto-aligned Journal Impact Factor commonly available

    Grantees should favour ORE when the priority is fast, mandate-compliant, no-cost open access — particularly for data notes, methods papers, or negative results that a conventional journal would reject. A traditional journal route remains preferable where a field’s tenure or promotion norms still weight Journal Impact Factor heavily, or where a non-Horizon co-funder specifies a different compliant venue.

    Answer-first Q&A

    What is Open Research Europe?

    Open Research Europe is the European Commission’s open-access publishing platform for researchers funded by EU programmes, launched in 2021. It uses open, post-publication peer review and, from autumn 2026, is jointly operated by CERN and a consortium of national research funders.

    Is Open Research Europe indexed in Scopus?

    Yes, conditionally. Every ORE article appears in Google Scholar immediately on publication. Once an article passes open peer review, it becomes discoverable in Scopus and Inspec as well, per LIBER Europe’s published FAQ on the platform.

    Can UK-funded researchers publish on Open Research Europe?

    Yes. Since the UK re-associated to Horizon Europe in 2024, UK-based researchers named on an eligible Horizon Europe, Horizon 2020 or Euratom grant retain the same fee-free publishing eligibility on ORE as researchers anywhere else in the programme.

    What this means for research offices

    Research administration teams should note one operational wrinkle: ORE’s open peer-review process generates multiple article versions, each with its own DOI. LIBER Europe’s guidance warns that repositories harvesting all versions — rather than just the latest — risk having duplicate-detection systems mistakenly flag or remove legitimate records.

    Institutions should update repository ingestion rules and internal open access guidance to reflect the 2026 eligibility expansion, and confirm with their research administration teams which national funders now sit inside the ORE consortium before advising grantees on venue choice.

    The CERN-hosted, multi-funder version of ORE launching in autumn 2026 is a concrete step toward the diamond open access model set out in Science Europe’s 2022 Action Plan for Diamond Open Access — a model likely to shape how Horizon Europe’s successor programme frames open access requirements after 2027.
