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.
