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.

Geprüft: 2026-09-18

Worauf zu achten ist

Separate economic scale from sustainability.

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.

Geprüft: 2026-09-18

Worauf zu achten ist

Look for interacting pressures and adaptation limits, not a single fix.

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.

Geprüft: 2026-09-18

Worauf zu achten ist

Do not confuse seagrass with seaweed.

Stocks, removals and avoided emissions

Existing stocks, annual net removals and avoided emissions are different measures. National greenhouse-gas inventory guidance is not the same as project credit certification.

Protect first; restoration is not instant recovery

Carbon lost from coastal wetlands may not fully recover within project timescales. Conservation, restoration and space for landward migration all matter.

High-quality blue carbon and community benefit

Practical principles connect additionality, permanence, leakage and verification with rights, participation, benefit sharing and biodiversity. They are not a certification scheme.

Ocean acidification and multiple stressors

Absorption of atmospheric CO₂ changes seawater chemistry. Its effects combine with warming, deoxygenation and local pollution, with different regional consequences.
