The relevance of autochthonous vs. allochthonous carbon in Blue Carbon ecosystems for climate change mitigation

As part of the research project FKZ 3722 42 510 0 ‘Climate protection measures in coastal regions and waters’


Blue Carbon ecosystems, such as mangroves, salt marshes, and seagrass meadows, play a vital role in climate mitigation by storing atmospheric CO₂ in their soils.

This paper highlights the critical need to distinguish between autochthonous (locally fixed) and allochthonous (externally sourced) carbon to ensure accurate carbon accounting. It states, that the inclusion of allochthonous carbon may overstate climate benefits and lead to over-crediting in carbon markets. To preserve environmental integrity, a conservative accounting approach is recommended, alongside stronger collaboration between scientific research and project developers.
