Forest blue carbon sink accounting: methodological advancements and uncertainty analysis

Key Points

• Blue carbon accounting methods show significant variability in estimates, highlighting uncertainty in coastal ecosystems' storage capacity.
• Key findings indicate that mangrove forests can sequester considerable carbon, with potential estimates differing by up to 40%.
• Analysis of existing methodologies reveals challenges in standardizing carbon sink measurements across different environments.
• These insights call for improved frameworks in carbon accounting to better understand the role of coastal ecosystems in climate mitigation.
