In the global totals oceans look nearly as protected as land — 14.0% to 16.4% — but country by country the median nation guards just 1.85% of its seas

Open the global scorecard and the two halves of the world's biggest conservation promise look like near-twins. As of 2024 the world has designated 16.4% of its land and 14.0% of its territorial waters as protected area, on the World Bank's area-weighted global figures. Read that pair and the natural conclusion is that the ocean, long the laggard, has nearly caught the land up. We pulled the same two indicators for every economy that reports them — terrestrial coverage for 213, marine coverage for 174, all at the 2024 vintage — and read them one economy at a time. The near-parity does not survive the descent from the global total to the individual country. The median economy has designated 16.9% of its land and 1.85% of its seas. The typical nation's ocean protection is about a ninth of its land protection, and the two figures are the story. The land half is broad. Of the 213 economies reporting terrestrial coverage, 106 — roughly half — already sit at or above 17%, the line the 2010 Aichi Target 11 set for 2020; 36 are at or above 30%; and 34 are under 5%. The sea half is thin and lopsided. Of the 174 reporting marine coverage, 114 are under 5%, 88 are under 2%, and 26 report zero. Set the two side by side for the 174 economies that report both, and 138 protect a larger share of their land than their sea; 32 protect more sea than land; four are level. The two numbers barely track each other across the set — the correlation between an economy's land and sea coverage is 0.28. So how does the global ocean figure reach 14.0% when the median economy is at 1.85%? Because the world total is area-weighted, and the average is dragged upward by size. The simple average across the 174 reporting economies is 9.6% — already far above the 1.85% median, meaning a long tail of high-coverage states. The area-weighted global figure (14.0%) sits higher still, which by construction means the economies with the most water tend to be the ones with the most of it protected. Which specific jurisdictions carry that weighted total cannot be read from coverage percentages alone — a state at 100% of tiny waters (Monaco, New Caledonia) adds far less to the global figure than a large-ocean state at a moderate share, and the marine-area weights needed to rank actual contributions are not in this coverage dataset. Regionally the pattern varies widely: the median economy in Europe and Central Asia protects 10.7% of its seas, against 1.85% in Latin America and the Caribbean, 1.0% across the Middle East and North Africa, 0.60% in East Asia and the Pacific, 0.60% in Sub-Saharan Africa, and 0.20% in South Asia. The pledge those numbers are read against is Target 3 of the Kunming-Montreal Global Biodiversity Framework, adopted by the parties to the UN Convention on Biological Diversity at COP15 in Montreal in December 2022. It asks the world to "ensure and enable that by 2030 at least 30 per cent of terrestrial, inland water, and of coastal and marine areas … are effectively conserved and managed". It is a single global figure — 30% of land and 30% of sea — and a collective one; it does not oblige each country to reach 30% on its own. Read as a yardstick against the country-level record, the land side has many economies near or past it and the sea side almost none: among the 174 that report both, 29 clear 30% on land, 16 clear it on sea, and just 5 clear it on both — Germany, New Caledonia, New Zealand, Palau and the Seychelles. Two boundaries belong at the top, not buried. First, these figures measure designated coverage — area a government has drawn a protected boundary around — not the "effectively conserved and managed" the pledge's own words require; a designation is not proof a place is managed, and the gap between paper and practice is not in this dataset. Second, the pattern is a strong majority, not a law: 32 of the 174 economies protect more of their seas than their land, and they include some large ocean states — the United States (19.0% sea against 12.9% land), Mexico (22.6% against 15.3%), Australia (45.4% against 22.0%), Chile (41.2% against 21.6%) and Colombia (41.1% against 17.0%). The land-heavy majority is the pattern; these are its real exceptions.

The following is analysis, not fact. Put on one screen, 16.4% of land and 14.0% of sea read as a story of convergence — the ocean nearly level with the land, the 30×30 pledge roughly half-met on both fronts. The country-by-country read says that is a composition effect, not a description of how the ocean is actually governed. A single area-weighted global percentage answers the question "what fraction of the planet's water sits inside a protected boundary," and for that question the economies with the largest marine areas weigh most heavily, and they tend to have higher-than-average coverage — which is why the weighted figure runs far above the typical country. The median economy — the ordinary case, the one that tells you what protection looks like in a typical country's seas — is at 1.85%. The distance between 14.0% and 1.85% is the distance between a global aggregate and a typical nation. What the whole-record read reveals is that land conservation has become a broad norm and ocean conservation the exception. Roughly half of all reporting economies have reached the old 17% land line; the median is a percentage point below it. At sea there is no comparable norm — the median is under 2%, most economies are under 5%, and the global figure that looks reassuring reflects area-weighting — the economies with the largest marine areas, which tend to have higher coverage, weigh most heavily in it — rather than a broad base of typical countries. That is consistent with the ocean being harder to enclose and later to the conservation effort than land ^sspeculative — an explanation the pattern fits, not a mechanism these coverage numbers isolate. It also reframes what "halfway to 30×30" means. On land, halfway is a real description of a broad base of countries. At sea, the same global halfway is an area-weighted figure that sits far above the typical country: the median is under 2%, so the aggregate does not describe a broad base of countries at or near 30×30. None of this speaks to whether any of the protected area, on land or at sea, is well managed — the indicator counts boundaries, and the pledge asks for management the boundaries do not guarantee. The most the data settles is the shape of the coverage: broad and near the old line on land, low for the typical economy and uneven across economies at sea.

The strongest objection is that we are reading a global target with the wrong unit. Target 3 is collective — 30% of the world's land and sea, not 30% in every country — so the fact that only 5 economies clear 30% on both is not a count of nations "in breach," and we do not present it as one. For the pledge as written, the area-weighted global figures (16.4% and 14.0%) are the honest scorecard, and by that measure the ocean is closer to the land than the country-level distribution suggests. The country read answers a different, legitimate question — what ocean protection looks like in a typical nation — and the two should not be confused. We report both and label which is which. Second, coverage is not conservation. The World Bank indicator counts designated area as a share of land or territorial waters; it says nothing about whether a park is funded, staffed or enforced. "Paper parks" are a real critique, and it cuts both ways: it can flatter a high-coverage state whose designations are nominal, and it means even the thin ocean figures may overstate what is actually managed. The robust claim here is about designated coverage and its distribution, not effectiveness, which this dataset cannot measure. Third, the marine denominator is not uniform. "Territorial waters" denominators are not perfectly uniform across the underlying records, and a few entries look like artifacts — a landlocked state carrying an inland-sea share, a tiny territory at near-100% ^sspeculative. These affect individual outliers, not the central finding, which rests on the median (1.85%) and the shares under 2% (88 of 174) and at zero (26), figures a handful of quirky denominators do not move. Fourth, the vintage is a baseline, not a verdict. The 2024 figures sit two years into an eight-year pledge; coverage has been rising, and the land and sea totals could converge further by 2030. The claim is about where the record stands now and how unevenly it is distributed, not about where it will end.

From a single seat the numbers look settled. A marine ministry reads its own two figures — say 16% of the land, under 2% of the water — and sees a familiar national fact, not a pattern. A global desk reads 16.4% and 14.0% and sees an ocean nearly caught up. Each view is accurate to its vantage, and each is blind to the other's. The ministry cannot see that its thin ocean number is the ordinary case, shared by most of the world; the global desk cannot see that its reassuring 14.0% is an area-weighted aggregate that runs far above the typical country the moment you read the countries one at a time. Stack all 174 marine records and all 213 land records at once and the two vantages resolve into one shape: a land total that a broad base of economies actually stands on, and an ocean total that area-weighting lifts far above a median of 1.85%.
