Blue Carbon

Blue carbon is the organic carbon captured and stored by coastal vegetated ecosystems, mangroves, tidal saltmarshes, and seagrass meadows, which bury carbon in waterlogged soils at rates per hectare far above most terrestrial forests and lock it away for centuries to millennia. Their loss releases that stored carbon, so conserving and restoring them is counted toward climate mitigation under several national greenhouse-gas inventories and carbon-market methods.
