New 'Ocean Protection Gap' Report Finds Just 3.5% of Ocean Effectively Protected

A report published September 23, 2026 by Systemiq in partnership with the Bloomberg Ocean Fund, Campaign for Nature, High Seas Alliance, Marine Conservation Institute, RISE UP, SkyTruth and WWF International found that while roughly 10% of the global ocean is now designated as protected or conserved (projected to reach 12% by 2030 on current trajectories), just 3.5% is assessed as 'effectively' protected — up only slightly from 2.8% in a 2024 assessment. The report found stark gaps by habitat: mangroves are 33% protected on paper but only 0.3% effectively so, and warm-water corals are 47% protected but less than 10% effectively. Authors identified three gaps holding back progress — ambition, implementation and finance — noting that only about $1.8 billion a year currently flows to ocean protection against an estimated $16 billion needed annually to meet the 30x30 target, even as effective protection could deliver an estimated $85 billion a year in economic benefits by 2050 through fisheries recovery and coastal ecosystem preservation.
