地中海の主要ブルーカーボン生態系であるPosidonia oceanica藻場を対象に、レクリエーション用アンカリングによる炭素蓄積損失を回避する取り組みを評価した。LIFE SeaForestプロジェクトは3つの保護海域で環境配慮型係留・持続可能なアンカリング管理・デジタルプラットフォームを導入し、10年間で累積5,000tCO2eq超の純排出削減（NER）を試算した。これは大気中CO2の直接削減量ではなく回避された潜在的炭素損失であり、認証可能なクレジット量の候補として位置づけられる。ブルーカーボンクレジット算定の再現可能な枠組みを提示する。
English
The LIFE SeaForest project developed an ex-ante accounting framework to estimate avoided carbon-stock losses from recreational anchoring damage to Posidonia oceanica meadows across three Mediterranean protected areas. Combining eco-friendly moorings, anchoring management plans, and a digital boating platform, it estimated cumulative net emission reductions exceeding 5,000 tCO2eq over ten years. This represents avoided potential carbon loss rather than directly measured atmospheric CO2 reductions, offering a replicable framework for blue carbon credit generation.

日本のGX文脈において
日本でも藻場・干潟のブルーカーボンクレジット（Jブルークレジット）制度が拡大しており、保全活動を炭素クレジット化する算定・検証手法の設計は国内制度の精緻化に示唆を与える。
In the global GX context
Blue carbon is an emerging frontier in global carbon markets and nature-based disclosure; this ex-ante accounting approach speaks to the methodological challenges of quantifying and verifying conservation-based credits under voluntary and compliance market standards.

📄 Abstract（原文）
Introduction Posidonia oceanica meadows are key blue carbon ecosystems in the Mediterranean Sea, storing substantial carbon within biomass and underlying sediments. Unregulated recreational anchoring contributes to meadow degradation and may compromise the retention of previously stored carbon. The LIFE SeaForest project (LIFE17 CCM/IT/000121) aimed to reduce carbon losses associated with P. oceanica degradation through integrated management, monitoring, conservation, and restoration actions across three Mediterranean protected coastal areas. Methods A comprehensive ex-ante accounting framework was developed to estimate anchoring-related potential carbon-stock losses, expressed in CO 2 -equivalent units, under baseline (business-as-usual) and project scenarios. The methodology considered vessel-size classes and substrate categories associated with P. oceanica (rocky, sandy, and degraded dead matte substrates). Project actions included environmentally friendly mooring systems, sustainable anchoring management plans, and regulation of recreational boating through a dedicated digital user platform. Results Over the ten-year accounting period, cumulative Net Emission Reductions (NERs) exceeded 5,000 tCO 2 eq across the three project areas. This value represents net avoided potential carbon-stock loss, rather than directly quantified atmospheric CO 2 emissions, and identifies a potential SeaForest credit volume subject to monitoring, verification, and certification. Discussion The proposed framework represents one of the first structured ex-ante approaches for estimating potential blue carbon credits from conservation measures that reduce anchoring impacts in Mediterranean P. oceanica meadows. Although further validation and long-term monitoring are needed, the SeaForest approach provides a potentially replicable framework for blue carbon initiatives, sustainable coastal management, and climate-mitigation policies in the Mediterranean region.
