Abstract

Blue carbon ecosystem restoration (and avoided conversion) are important natural climate solutions. Blue carbon ecosystems accumulate carbon through in situ photosynthesising vegetation (autochthonous) and deposition of sediments during tidal inundation (allochthonous). We debate the treatment of allochthonous carbon (which was not taken out of the atmosphere by the blue carbon ecosystem) in blue carbon projects.
