Ocean economy vs sustainable blue economy

The scale of ocean-linked activity is not the same as a sustainable blue economy. Compare figures only after checking sector scope, value-added measures and base years.

Ocean, coastal ecosystems and climate risk

Warming, sea-level rise, deoxygenation and acidification interact across ecosystems and coastal livelihoods. Local action must sit alongside global emissions cuts.

Checked: 2026-09-18

Established coastal blue carbon ecosystems

Mangroves, tidal and salt marshes, and seagrass meadows form the core internationally recognised blue carbon ecosystems. Much of their carbon is held in soils and sediments.
