Protected Ocean Area Growth
Global ocean area officially protected (UNEP-WCMC Protected Planet 2026)
Historical Timeline
Minimal ocean protection, mostly small coastal marine reserves
CBD Aichi Target 11 sets goal of 10% marine protection by 2020
Large-scale MPAs established: Ross Sea (Antarctica), Cook Islands, Chile
High Seas Treaty adoption accelerates international water protection
Official 10.0% milestone reached on Protected Planet database; target 30% by 2030
Key Insights
10% Milestone Achieved
Total designated marine protected and conserved areas reached 10.0% of world oceans, marking significant formal designation progress toward the 30x30 goal.
High Seas Treaty (BBNJ)
The UN High Seas Treaty enables marine protected area creation in international waters (64% of oceans), safeguarding open-ocean migratory pathways.
Protection Quality Gap
While 10.0% is officially designated, MPAtlas estimates ~3.3% is fully or highly protected from industrial fishing and extraction, emphasizing enforcement needs.
