Landmark High Seas Treaty Ratified, Empowering Coastal Communities
26 Sep, 2025
Summary
- 73 countries ratify treaty to protect international waters
- Treaty advances UN goal of 30% ocean protection by 2030
- Gives Indigenous, developing nations a voice in policy-making

Last week marked a significant milestone for ocean conservation, as 73 countries, including the European Union, ratified a treaty to establish environmental protections on international waters. This vast, unregulated area of the ocean, often referred to as the "Wild West," has long been plagued by dangerous and unregulated activity, leading to the mass destruction of critical marine life and ecosystems.
The ratification of the High Seas Treaty is a major victory for both marine and human life. It lays the groundwork for countries to determine areas of the high seas that should be protected from fishing, industrial activity, and other threats. Importantly, the treaty also gives Indigenous communities, developing nations, and the Global South a seat at the table, allowing them to lend their voices to the policy-making process.
While the treaty does not go into effect until January, some nations are already taking proactive steps to implement it. Chile has launched an initiative to encourage countries to begin mapping out areas of the high seas that should be protected, and the Economic Community of West African States (ECOWAS) is working to collect data, evaluate protected areas, and develop a regional strategy to protect biodiversity.
