BLUE CARBON
Coastal wetlands (e.g. supratidal forests, mangroves, saltmarshes, seagrasses) are collectively known as Blue Carbon ecosystems.
Through the natural process of biosequestration, coastal wetlands capture carbon dioxide 30-50 times faster than terrestrial forests, which they lock away in the ground for millennial time-scales. Given their ability to trap atmospheric CO2, they act as natural carbon sinks, help offset our emissions and contribute to fight climate change.
Their importance:
Speedy capture
can trap carbon 30-50 times faster than typical terrestrial forests
Long-term storage
store 80% of the carbon in belowground sediments, it is locked away for centuries to millenial timescales
Additional services
enhance biodiversity, support fisheries, provide ecotourism revenues, and protect our coasts against erosion and extreme weather events
