The Ocean Protection Gap Report 2026

The Ocean Protection Gap Report 2026 takes a deep dive into progress towards 30×30 in the ocean, one of the target’s greatest implementation gaps. It accompanies the 30×30 Global Assessment, a comprehensive analysis of progress across land and ocean, which finds the target remains within reach but urgent government action is needed. Together, the reports set out what is needed to accelerate effective protection through 2030.

The global target to protect and conserve at least 30% of the world’s land and ocean by 2030 (30×30) was agreed by countries under the Kunming-Montreal Global Biodiversity Framework in 2022, and is to be delivered through protected areas and other effective area-based conservation measures.

Four years from the 2030 deadline, around 10% of the ocean has been designated as protected or conserved – one third of the target.

And just 3.5% of the global ocean is assessed as effectively protected.

Progress is being made on 30×30 in the ocean, but not at the speed required. Since 2022, marine and coastal coverage has increased by approximately 1.7%. If recent trends continue, global marine coverage would reach only around 12–15% by 2030.

Reaching 30×30 will therefore require increased ambition alongside much faster implementation – in both national waters and on the high seas.

More ocean must be protected. Designation must become effective protection. And finance must follow.

The Ocean Protection Gap Report identifies three connected challenges that must be addressed to deliver 30×30 in the ocean: the ambition gap, the implementation gap, and the finance gap. Together, these form the ocean protection gap.

Around half of coastal countries currently have a timebound and quantified national ocean protection target. Even if existing quantified national commitments are fully delivered, global marine and coastal protection would reach only around 12% by 2030 – far short of 30%.

Closing that gap will require governments to raise ambition both within and beyond national borders.

The High Seas make up around two-thirds of the global ocean but remain largely absent from existing protection commitments. The High Seas Treaty creates the first legally binding global framework for conserving biodiversity in these waters – opening a major new pathway to expand protection before 2030.

What needs to happen

Governments must increase national 2030 targets where ambition falls short, and use the High Seas Treaty to advance a first wave of effectively protected areas in priority high-seas ecosystems.

“With less than 2% of the High Seas protected, implementing the High Seas Treaty that entered into force earlier this year, represents the biggest opportunity to supersize progress towards 30×30.”

Rebecca Hubbard, Director of the High Seas Alliance

Pie charts comparing ocean protection in national waters and on the high seas. National waters make up 39% of the global ocean: 8% is effectively protected and 16% is reported but not effectively protected. The high seas make up 61% of the global ocean: under 1% is effectively protected and 1% is reported but not effectively protected.

Designation is not the same as protection.

Around 10% of the global ocean is designated for conservation, but just 3.5% is currently assessed as effectively protected, using fully and highly protected areas as a proxy. In many areas counted towards global conservation targets, destructive activities such as bottom trawling continue.

The gap is particularly striking in some of the ecosystems protection is intended to safeguard. Around 33% of mangroves are reported as protected, yet just 0.3% are fully or highly protected. For seagrass, the figures are 34% and 1.1%. And while 47% of warm-water corals fall within protected areas, less than 10% are fully or highly protected.

What needs to happen

Governments must strengthen existing protected and conserved areas through effective management, equitable governance, sufficient long-term finance, monitoring, and enforcement, while ensuring new protected areas in national waters are designed to deliver effective protection. As protection expands in the High Seas, these conditions must be built into the first generation of protected areas from the outset.

“Designation alone is not enough. The majority of existing marine protected areas are still not delivering effective conservation.”

Lance Morgan, President, Marine Conservation Institute

Bar chart of protection by coastal and marine ecosystem. Fully or highly protected: mangroves 0.26%, cold-water corals 6.22%, warm-water corals 9.57%, seagrass 1.08%, salt marsh 0.02%. Protected but not fully or highly protected: mangroves 33.13%, cold-water corals 28.90%, warm-water corals 47.20%, seagrass 33.52%, salt marsh 20.39%.

Protection cannot be implemented or sustained without finance.

Delivering marine 30×30 is estimated to require approximately USD $16 billion annually. Current spending is estimated at only around USD $1.8 billion, with 9-10 times more funding needed to match global ambition with the resources required to deliver it.

The solutions are not starting from zero. Domestic public budgets, conservation trust funds, Project Finance for Permanence, debt conversion, and blended finance all provide models that can support conservation. At the same time, new technology is helping to reduce the cost of protecting and managing ocean areas. The challenge is increasingly one of political will: deploying proven approaches at much greater speed and scale.

Previous analysis identified at least US $85 billion in potential annual economic benefits by 2050 from healthier fisheries, coastal protection, and conserved blue carbon ecosystems.

What needs to happen

Governments, donors, philanthropies, and private-sector actors must substantially increase long-term finance for marine conservation and connect funding more directly to credible implementation plans.

Ocean protection finance: USD 1.8 billion invested each year against USD 15.8 billion needed each year, leaving a USD 14 billion annual finance gap.

A line on a map is the beginning of ocean protection, not the end.

For 30×30 to deliver for biodiversity and people, protected and conserved areas need effective management, equitable governance, long-term finance, and safeguards against destructive activities. They also need to protect the places that matter most – from threatened-species habitats and migratory corridors to reefs, mangroves, seagrass, and deep-sea ecosystems.

Governments have agreed the destination. The priority now is turning 30×30 into effective protection on the water.

The pathway is clear: increase ambition where commitments fall short, implement the protection already promised, use the High Seas Treaty to accelerate action beyond national waters, and mobilize the finance required to make conservation last.

  • Make 30×30 a political priority through the remainder of the decade.
  • Translate national targets into mapped, costed, financed, and timebound implementation plans.
  • Increase ocean-protection ambition where current commitments fall short, prioritizing important and underrepresented ecosystems and areas of high biodiversity value.
  • Ratify and move rapidly to implement the High Seas Treaty, including advancing credible proposals for a first wave of high-seas marine protected areas.
  • Ensure new and existing protected and conserved areas are effectively managed, equitably governed, monitored, enforced, and financed for the long-term.
  • Recognize and support the rights, leadership, knowledge, and conservation contributions of Indigenous Peoples and local communities, including through direct access to finance.
  • Report transparently on protection, management effectiveness, governance, finance, and biodiversity outcomes.
  • Scale finance towards the approximately USD $16 billion required annually for marine 30×30, compared with around USD $1.8 billion in current annual spending.
  • Prioritize long-term funding that enables protected areas to move from designation to effective implementation.
  • Scale proven mechanisms including conservation trust funds, Project Finance for Permanence, debt conversion, and blended finance.
  • Connect funding to credible national implementation plans and conservation outcomes, rather than coverage alone.
  • Support the scientific cooperation, monitoring, enforcement, and implementation capacity required to turn the High Seas Treaty into effective protection.
  • Keep 30×30 implementation visible and accountable through the 2030 deadline.
  • Support governments and rights-holders to turn commitments into practical, spatially explicit, and financed conservation plans.
  • Champion protection that delivers measurable biodiversity outcomes rather than nominal gains in coverage.
  • Help build political and financial support for ambitious implementation of the High Seas Treaty.
  • Support and amplify Indigenous Peoples and local communities as rights-holders, governance partners, and conservation leaders.
  • Use transparent data and evidence to track progress and identify where action is falling behind.

It builds on the methodology and approach established in the previous Ocean Protection Gap Report.

The report uses the Marine Conservation Institute’s MPAtlas analysis of fully and highly protected zones as a proxy for the share of the ocean that is effectively protected. This distinction is important: areas designated for conservation are not necessarily managed or regulated at a level that delivers effective protection from destructive activities.
