The project aims to deliver significant and verifiable progress towards the Mission “Restore our Ocean and Waters by 2030” goals. This includes demonstrable progress towards multiple objectives of the Mission as outlined in the Mission Implementation Plan. It also aims to support Member States, regional, and local authorities, along with other stakeholders, in implementing EU marine and freshwater ecosystem legislation, contributing to the biodiversity, pollution, and climate targets of the European Green Deal. Additionally, the project seeks to engage and mobilize Mission communities such as regions, ports, cities, and islands to accelerate the achievement of Mission objectives. Leveraging resources and investments from community actors to restore oceans, seas, and waters is another crucial aspect. The project also focuses on increasing local readiness to deploy innovative solutions at scale for ocean, seas, and water restoration. During the deployment and upscaling phase (Phase 2 starting in 2026), the Mission aims for broad participation across the EU, with strong citizen, stakeholder, and community governance. Transitioning from development and piloting (Phase 1) to deployment requires mobilizing various actors to undertake significant actions for ocean, seas, and water restoration. Therefore, support is needed for established and emerging community actors to implement innovative actions at scale. Each proposed action should address one of the four basins under the Mission “Restore our Ocean and Waters by 2030” and provide three types of support.Each proposed action should address one of the four basins under the Mission “Restore our Ocean and Waters by 2030” and provide: Cascading Grants to Community-led Pilot Actions: Award at least five cascading grants (EUR 200,000 - EUR 2 million each) to community-led pilot actions implementing innovative solutions. Ensure a transparent, objective, and fair selection process for third parties receiving financial support. Promote cascading grant calls at various levels to reach potential applicants. The third-party actions should focus on ambitious progress towards Mission objectives, combining technological, nature-based, social, cultural, regulatory, financial innovation, and new governance models. Encourage collaboration with scientific institutions and inclusion of Social Sciences and Humanities (SSH) disciplines. Build on research and innovation from previous EU programmes and make use of resources like Copernicus/Galileo/EGNOS and Emodnet. Attract additional financing from various funds or private sources. Cascading Grants for Transition Agendas: Award at least 20 grants (up to EUR 100,000 each) for transition agendas. Transition agendas are strategic roadmaps to meet Mission objectives, focusing on local community needs. Ensure the selection process is transparent, objective, and fair. Entities developing transition agendas must report progress within six months. Technical Assistance to Mission Communities: Provide tailored technical assistance for business plans, feasibility studies, impact assessments, capacity building, and other support. Empower local stakeholders and encourage long-term commitment to ocean, seas, and water restoration. Promote clustering and networking among community-led actions for enhanced communication, collaboration, and impact. Assist in forming partnerships with local communities, NGOs, and stakeholders. Guide community-led actions in accessing additional funding and deploying feasible solutions. Ensure collaboration with other Horizon Europe projects, Mission lighthouse CSA projects, the Mission Implementation Platform, and other relevant initiatives. The types of Mission communities relevant to the cascading grants may include at least the following: ports (including inland ports); islands; fishing communities, aquaculture producers and other representatives of blue economy; operators of various vessels; Local Action Groups described by the Community-Led Local Development strategies [6] waterfront cities or regions / communities (avoiding overlaps with Cities’ Mission); conservation communities; representatives of the tourism sector; maritime infrastructure operators (incl. offshore platforms and their operators).
