High Seas Treaty enters into force

Published · Researched 2026-09-22

What happened (dated facts)

  • The Agreement on Biodiversity Beyond National Jurisdiction (BBNJ), known as the High Seas Treaty, entered into force on January 17, 2026.
  • It is the first international treaty to allow the creation of marine protected areas (MPAs) on the high seas, which cover nearly half the planet's surface.
  • The treaty also establishes rules for environmental impact assessments and the sharing of marine genetic resources.
  • WWF and IDDRI analyses (January 2026) frame it as a landmark for ocean governance, while noting that designating the first high-seas MPAs and convening the first Conference of the Parties remain ahead.

Why it is genuinely positive

A legally binding global ocean-protection framework is now in force after two decades of negotiation — a completed diplomatic outcome that unlocks future high-seas conservation.

Social pulse
