A historic moment is on the horizon: the High Seas Treaty is entering into force on 17 January 2026, marking a new era for the protection of our shared ocean. This milestone shows what is possible when countries come together to safeguard the blue heart of our planet, and it deserves to be celebrated across the world.
To mark this occasion, we’re planning a global day of action, and we want you to be part of it. From beach gatherings to art installations, from panel discussions to online campaigns, everyone can take part in celebrating this collective victory for the ocean. But this is also a moment to call on countries to keep the momentum going to continue ratifying the Treaty, establish the institutions and processes needed for its success, and ensure it delivers real protection.
Over the next few weeks, we’ll be sharing more details on HSA activities to mark the day. But you don’t have to wait to get involved, start planning your event or action now!
- Organize something in your community, big or small, and let us know what you’re planning.
- We’ll help amplify your event by sharing it across our networks and adding it to the global schedule of activities.
- Share your ideas and planned activities with us at info@highseasalliance.org
