The European Ocean Days is a week-long event with a series of dynamic and interconnected sessions focused on key ocean-related themes, all designed to encourage participants to engage across topics and contribute to a shared vision for the prosperity, competitiveness, security and sustainability of our ocean.

To ensure that the Coalition of cities, regions, islands and ports for the Mission Ocean and Waters responds to real needs on the ground, CO-WATERS is also organising an in-person needs assessment workshop as a follow-up to its online consultation activities.

This event will bring together representatives from regions, cities, ports, and islands to celebrate the growing community supporting the Mission Ocean and Waters. The fully interactive session will invite participants to share their experiences and show how their actions make a difference. Building on the shared vision for restoring the ocean and waters, set out in the European Ocean Pact and the Water Resilience Strategy, the event will spotlight the communities active across the four Mission Lighthouse sea and river basins, showcasing successful initiatives, exploring the value of different forms of support and technical assistance, and discussing lessons learnt and remaining needs.

The fourth Annual Forum of the Mission 'Restore our Ocean and Waters' aims at taking stock of the Mission's progress and major achievements, at mobilising relevant actors around key Mission deliverables for the deployment phase. The event will showcase innovative solutions developed under the Mission, discuss how key stakeholders, such as the regions, local authorities and the private sectors are involved in implementing the Mission and how different streams of finance are being mobilised to support the scaling and deployment of solutions for reaching the Mission objectives: to protect and restore marine and freshwater ecosystems and biodiversity, boost coastal resilience, eliminate pollution, and make the blue economy climate-neutral and circular.

The Summit is centred around driving action for a sustainable ocean economy and leveraging the ocean as a key part of the global environmental, social and economic agenda.
