- Max. EU Contribution per Project: €23.3 million (estimated)
- Submission Model: Single stage
- Opening Date: 07 May 2025

Mission Context
This topic is part of the EU Mission *“Restore our Ocean and Waters by 2030.”* Projects must deliver measurable progress toward the three Mission objectives:
1. Protect & restore marine and freshwater ecosystems and biodiversity.
2. Prevent & eliminate pollution ("Zero Pollution" ambition).
3. Make the blue economy carbon-neutral & circular.
Scope Highlights
* Demonstrate systemic, place-based, people-centred solutions on ≥ 6 islands, with ≥ 2 islands per lighthouse basin (Atlantic/Arctic, Mediterranean, Baltic/North Sea).
* Strong participation of island public authorities as full partners is *strongly encouraged*.
* Emphasis on nature-based solutions, land-sea interactions, climate-resilient design and socio-economic co-benefits.
* Mandatory activities include impact assessment, stakeholder engagement (incl. living labs & citizen science), innovative finance schemes, and replication planning.
Funding Rules & Rate
Innovation Actions are funded at 70 % of eligible direct costs (100 % for non-profit entities) + 25 % flat-rate indirect costs. Co-funding, especially via structural funds, EMFAF, LIFE, private investment or blended finance, is not only eligible but strategically recommended.
Expected Outcomes
* Quantifiable progress toward Mission targets by 2030 (KPIs linked to habitat restored, pollution reduction, GHG emissions, jobs created, investment leveraged, etc.).
* Increased readiness of island authorities to deploy & upscale innovative solutions.
* Strengthened resilience of island communities to extreme events & sea-level rise.
> Take-home message: The Commission will fund a few large-scale demonstrators (€15-23 m each) capable of acting as living labs and blueprints for hundreds of islands across your country and beyond.

🇪🇺 Strategic Advantages
EU-Wide Advantages & Opportunities for "Restoring Ocean and Waters on Islands" (HORIZON-MISS-2025-03-OCEAN-06)
1. Strategic Fit with Core EU Agendas
Why it matters at EU scale: The call is a direct delivery mechanism for the EU Mission "Restore our Ocean and Waters by 2030", one of five flagship missions of Horizon Europe. By targeting islands, it operationalises multiple high-level strategies in a single action, ensuring policy coherence and maximising political visibility.
• European Green Deal & Climate Law – contributes to climate-neutrality via carbon-neutral blue economy pilots.
• EU Biodiversity Strategy & Nature Restoration Regulation – implements quantified restoration targets in sensitive coastal ecosystems.
• Zero-Pollution Action Plan – island testbeds provide controlled settings for land-to-sea pollution abatement.
• Sustainable Blue Economy Strategy – accelerates market uptake of circular, low-carbon maritime technologies.
2. Single Market Access (450+ million consumers)
• Demonstrated technologies (e.g. advanced wastewater treatment, nature-based coastal defence, marine bio-products) can be commercialised EU-wide under a single CE-marking/regulatory regime.
• Procurement leverage: island public authorities can aggregate demand through cross-border joint procurement, shortening time-to-market for innovative products.
• Tourism multiplier: 150 million yearly visitors to EU islands become early adopters and ambassadors of eco-innovations, expanding market pull beyond local populations.
3. Cross-Border Collaboration & Knowledge Exchange
• Mandatory coverage of at least 6 islands in 3 sea-basin lighthouses hard-wires multinational consortia, pooling scientific excellence from northern, southern and outermost regions.
• Facilitates comparative piloting (different biogeographical contexts) → stronger evidence base for EU-wide standards.
• Enables sharing of scarce island expertise (e.g. off-grid renewables, water-energy nexus) and optimises use of public funds.
• Supports Mission Ocean governance structures (Lighthouse CSAs & Mission Implementation Platform) to disseminate good practice to 1 200+ European islands.
4. Regulatory Harmonisation Benefits
• Solutions tested under common EU directives (WFD, MSFD, Nature Restoration, INSPIRE, Renewable Energy Directive) enjoy smoother replication across Member States.
• Early alignment with upcoming tools (coastal restoration contracts, river contracts, Digital Twin Ocean) minimises later compliance costs.
• Joint monitoring protocols based on EMODnet & EOSC foster comparable data, easing transboundary water management and reporting obligations.
5. Plug-in to Europe’s Innovation Ecosystem
• Access to 40+ ESFRI marine & climate research infrastructures (EuroSea, DANUBIUS-RI, ICOS, etc.) for high-resolution data and testing facilities.
• Synergies with Clean Energy for EU Islands secretariat, ERRIN Blue Economy working groups, KICs (EIT Climate-KIC, EIT InnoEnergy) and Enterprise Europe Network for commercial matchmaking.
• Direct link to Digital Twin Ocean development – island pilots can become premium data demonstrators, attracting additional DTO budgets.
6. Funding Synergies & Leverage
• Grant budget acts as a catalyst to crowd-in Cohesion Policy funds (ERDF, ESF+, JTF) for infrastructure build-out and LIFE/EMFAF for conservation actions.
• Islands may sign Cooperation Working Arrangements to blend Mission funds with regional programmes, multiplying impact and ensuring post-project continuity.
• Private capital mobilisation via InvestEU Blue Economy window and Green Bond Standard for nature-based coastal projects.
7. Scale, Replicability & EU-Level Impact
• "Living-lab on an island" = high visibility, contained geography, fast feedback loops → ideal for proof-of-concept before mainland roll-out.
• Mandatory replication plan to additional islands embeds scaling in project DNA, feeding the 2026-2030 deployment phase of the Mission.
• Contribution to SDGs 6, 13 & 14 positions EU as global leader ahead of UN Ocean Conference 2027, opening export markets for EU firms.
8. Unique Strategic Value of Operating at EU Level
• Critical mass of diverse ecological, socio-economic and governance contexts unavailable in any single country.
• EU branding provides credibility, de-risks private investment and eases citizen acceptance through a shared vision.
• Centralised dissemination via CORDIS, EMODnet and Mission events guarantees EU-wide visibility for partners’ IP and business models.
9. Actionable Opportunities for Applicants
1. Build tri-basin consortia pairing small, vulnerable islands with well-resourced outermost regions to showcase solidarity and attract cohesion funding.
2. Integrate nature-based solutions + digital twins to tap both Mission Ocean and Digital Europe budgets.
3. Align island pilots with forthcoming River Basin Management Plan revisions (2027 cycle) to secure regulatory fast-tracking.
4. Engage tourist operators and ferry companies as associated partners to open large-scale awareness channels and circular economy loops.
5. Prepare an EU-wide Joint Procurement Framework for restoration technologies, using the project as pre-commercial validation phase.
---
Bottom line: Leveraging EU-level instruments, policy coherence and the single market turns island restoration from isolated local projects into scalable European transition accelerators—de-risking innovation, unlocking multi-source finance and positioning participants at the forefront of the €200 bn/yr sustainable blue economy.
