Agenda 2030

14

Life Below Water

Conserve and sustainably use the oceans, seas and marine resources for sustainable development

Key Targets
  • 1 By 2025, prevent and significantly reduce marine pollution of all kinds.
  • 2 By 2020, sustainably manage and protect marine and coastal ecosystems.
  • 3 Minimize and address the impacts of ocean acidification.
  • 4 By 2020, effectively regulate harvesting and end overfishing.
  • 5 By 2020, conserve at least 10 per cent of coastal and marine areas.
Key Facts
Oceans cover 70% of the planet and absorb 90% of excess heat from global warming.
Over 3 billion people depend on marine and coastal biodiversity for their livelihoods.
Around 80% of marine pollution originates from land-based activities.
By 2050, there could be more plastic in the ocean than fish by weight.
Global Progress

Oceans cover 70% of our planet and are the lifeblood of Earth's climate, food systems, and biodiversity. While marine protection has expanded and international governance frameworks have improved, ocean warming, acidification, and plastic pollution are accelerating and many key 2020 targets were missed entirely.

What We've Accomplished

  • Marine protected areas grew from under 1% of ocean in 2000 to 8.3% by 2023.
  • The UN High Seas Treaty (2023) established a framework to protect international waters for the first time.
  • WTO agreement to end harmful fishing subsidies adopted in 2022 — first trade agreement focused on sustainability.
  • Several countries eliminated single-use plastics through national legislation.
  • Coral reef restoration programs successfully expanded in Australia, the US, and the Maldives.

2030 Outlook

Off Track

Ocean surface temperatures hit record highs in 2023, causing mass coral bleaching events on a global scale. Overfishing persists in 35% of monitored fish stocks. Plastic pollution is projected to triple by 2040 without intervention. Ocean acidification has increased 26% since the Industrial Revolution. The 2020 target to protect 10% of coastal and marine areas was missed; the revised 30% by 2030 target will require an unprecedented expansion of protection regimes.

Leading Nations

Palau Created one of the world's largest marine sanctuaries — protecting 80% of its waters from fishing and extraction.
New Zealand Motu Moana marine reserve expansion and world-leading Kaitiakitanga (ocean guardianship) policies.
Norway Leads in sustainable fisheries management; strict quotas help maintain healthy North Sea fish populations.
Seychelles Protected 30% of its ocean — exceeding the global 2030 target already — through a debt-for-nature swap.
European Union Common Fisheries Policy and marine spatial planning among the most comprehensive ocean governance systems.
