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

Summary

This document from the German Environment Agency addresses the critical challenge of accurately quantifying carbon sequestration in Blue Carbon ecosystems, highlighting the distinction between autochthonous (internally produced) and allochthonous (externally sourced) carbon. The paper emphasizes that allochthonous carbon should be excluded from carbon accounting for mitigation projects, as it does not meet additionality criteria for carbon credits. As part of ongoing research, it discusses various approaches for determining carbon origin and proposes improvements for future quantification in voluntary carbon markets.
