ブルーカーボン生態系（マングローブ、干潟、海草藻場、海藻）が気候変動緩和に急速に統合されている。マングローブがプロジェクトの約89%を占め、世界の回復可能性は年間約1億900万トンの有機炭素除去をもたらすが、生息地喪失は年間最大6300万トンの排出を引き起こす。炭素利益を実現するにはMRVコストやデータ不足が制約であり、優先分野として空間マッピング、輸送モデリング、排出係数開発、新たな炭素経路の統合を特定している。
English
Blue carbon ecosystems (mangroves, marshes, seagrasses, seaweeds) are rapidly integrated into climate mitigation. Mangroves dominate ~89% of projects. Global restoration could deliver ~109 MtC/year removals, while habitat loss causes ~63 MtC/year emissions. Monitoring, reporting, and verification costs and data gaps constrain benefits. Four priority areas: spatial mapping, lateral/vertical transport modeling, emissions factors, and novel carbon pathways.

📄 Abstract（原文）
Blue carbon ecosystems—mangroves, tidal marshes, seagrass meadows, and, increasingly, seaweeds—are being rapidly integrated into climate mitigation frameworks. Yet, despite their prominence in global carbon offset discourse, blue carbon projects remain dominated by mangroves (∼89% of projects). Here, we synthesize recent developments in blue carbon science, carbon accounting, and market integrity. Global restoration potential could deliver annual removals of ∼109 (98–119; 95% CI) million tonnes of organic carbon, while habitat loss causes annual emissions of up to ∼63 (55–71) million tonnes. Realizing carbon benefits is constrained by monitoring, reporting, and verification costs, data gaps, and methodological challenges. We identify four priority areas for advancing blue carbon crediting: ( a ) spatial mapping, particularly for seagrasses and seaweeds; ( b ) lateral and vertical carbon transport modeling, ( c ) emissions factor development, and ( d ) incorporation of novel carbon pathways (e.g., alkalinity export). As blue carbon definitions expand and demand for implementation accelerates, ensuring scientific rigor and project integrity is critical to scaling restoration that delivers durable climate and biodiversity gains.
