This article relates to Goal 14: Life below water, one of the 17 UN Sustainable Development Goals. Goal icon by the United Nations. Emberoot is not affiliated with, or endorsed by, the UN.
SDG 14, life below water, is the UN Global Goal for the ocean. Its official wording is “Conserve and sustainably use the oceans, seas and marine resources for sustainable development”. In practice that means cleaner seas, fewer overfished stocks, more protected areas and fairer access for small fishers. This guide explains the targets, where the world stands in 2026, and what is off track.
What SDG 14 life below water covers
Goal 14 has ten targets, listed on the UN’s Goal 14 page. Seven are outcome targets and three are about the means to reach them. In plain English:
- 14.1: by 2025, sharply reduce marine pollution, especially from land, including litter and nutrients.
- 14.2: manage, protect and restore marine and coastal ecosystems.
- 14.3: reduce and tackle ocean acidification.
- 14.4: end overfishing, illegal fishing and destructive practices, and rebuild fish stocks.
- 14.5: conserve at least 10% of coastal and marine areas.
- 14.6: ban fisheries subsidies that drive overfishing and illegal fishing.
- 14.7: raise the economic benefits small island states and least developed countries get from the sea.
- 14.a, 14.b and 14.c: share marine science and technology, give small-scale fishers access to resources and markets, and apply the law of the sea.
Several of these targets carried deadlines of 2020, and target 14.1 carried a 2025 deadline. Those dates have passed without the targets being met in full.
Why the ocean matters
The UN oceans page sets out the basics. The ocean covers about three-quarters of the planet, holds 97% of its water and absorbs about 29% of human CO2 emissions and more than 90% of the excess heat in the climate system. Fisheries are the main source of protein for more than half the people in the least developed countries. Coastal areas host around 80% of global tourism.
Where the world stands in 2026
The Sustainable Development Goals Report 2026 gives the latest picture. On fishing, 35.5% of assessed marine stocks were overfished in 2021, the latest year with data, and 64.5% were within biologically sustainable levels. Measured by volume, 77.2% of the catch came from sustainable stocks. The share of sustainable stocks has slipped about two percentage points over six years.
On acidification, average surface ocean pH has fallen from 8.11 to 8.04 over the past 40 years, according to the World Meteorological Organization. Monitoring is growing: pH stations rose from 178 in 2021 to 906 in 2026 across 45 reporting countries, though only 13 countries submit data covering more than a decade.
On protection, 10.01% of the ocean was officially protected or conserved in April 2026. That finally crosses the 10% level in target 14.5, six years after its 2020 deadline. The newer global goal, agreed under the Kunming-Montreal Global Biodiversity Framework, is 30% by 2030. On the high seas, beyond national waters, coverage is only 1.66%.
The good news: two treaties in force
Two long-negotiated agreements came into force recently. The WTO Agreement on Fisheries Subsidies took effect on 15 September 2025 and has been accepted by 120 members, according to the 2026 report, which puts harmful fisheries subsidies at about $22 billion a year. The Agreement on Marine Biological Diversity of Areas beyond National Jurisdiction, known as the BBNJ Agreement or High Seas Treaty, entered into force on 17 January 2026. It covers the two-thirds of the ocean outside national limits, and 89 countries were parties by 1 June 2026. According to the UN BBNJ Agreement site, it deals with sharing the benefits of marine genetic resources, protected areas and other area-based tools, environmental impact assessments, and capacity building and technology transfer.
What is off track
Pollution is the clearest miss. The UN estimates that between 5 and 12 million tonnes of plastic enter the ocean every year, and about 89% of plastic litter on the ocean floor is single-use items. Warming adds pressure: the fourth global coral bleaching event affected 84% of reefs across 83 countries and territories, according to NOAA data cited by the UN. And while the sustainable share of fish stocks keeps edging down, the benefits of fishing for small island states have also fallen, from 0.57% to 0.52% of their GDP between 2021 and 2023.
Goal 14 links closely to climate action, since the ocean absorbs so much heat and carbon. Our Global Goals hub collects all 17 goals, and the Goal 14 page keeps targets and data in one place. Organisations planning their response can start with our strategy work.
Frequently asked questions
What is SDG 14 in simple words?
SDG 14 is the UN Global Goal for the ocean, called life below water. It aims to cut marine pollution, end overfishing and illegal fishing, reduce ocean acidification, protect more of the sea, remove harmful fishing subsidies and help small island states and small-scale fishers benefit fairly from marine resources.
Is the world on track for SDG 14?
Mostly not. Several targets had 2020 or 2025 deadlines that passed without being met, more than a third of assessed fish stocks were overfished in 2021, and ocean pH keeps falling. There is progress: protected areas passed 10% of the ocean in 2026, and two major treaties on fishing subsidies and the high seas are now in force.
What is the High Seas Treaty?
It is the BBNJ Agreement on marine biodiversity in areas beyond national jurisdiction. It entered into force on 17 January 2026 and covers about two-thirds of the ocean. It creates a way to set up protected areas on the high seas, requires impact assessments for new activities and sets rules for sharing marine genetic resources.
