High Seas Treaty Reaches 60 Ratifications, Will Enter Into Force in January 2026

Countries will convene a first conference within a year of entry to finalize governance, financing and procedures.

Overview

  • Morocco and Sierra Leone delivered the decisive ratifications, activating a 120‑day countdown to entry into force.
  • The agreement applies to waters beyond national exclusive economic zones covering about 60% of the ocean, where roughly 1% has legal protection today.
  • It establishes processes for high‑seas marine protected areas, environmental impact assessments and benefit‑sharing of marine genetic resources.
  • A conference of the parties will make decisions multilaterally, and only countries that ratify before the first meeting can vote on foundational rules.
  • Experts estimate the first protected areas under the treaty may not be designated until 2028–2029, as overfishing and prospective deep‑sea mining continue to pressure international waters with no commercial mining licenses issued yet.
