日本語
本レビューは、生物的・バイオ炭・地球化学的・海洋・工学的CDR経路におけるMRV・会計の枠組みを2015〜2026年の文献で評価。カウンターファクチュアル基準、追加性、ライフサイクル排出、漏れ、タイミング、不確実性、貯留期間、反転リスクの明示が信頼性に不可欠と指摘。AIやリモートセンシングは各段階を強化し得るが検証要件は経路ごとに異なり、登録簿は測定・会計規則の弱さを補えないと結論。
English
This review evaluates MRV and accounting frameworks for biological, biochar, geochemical, oceanic, and engineered CDR pathways (2015-2026). Credible accounting requires explicit treatment of baselines, additionality, lifecycle emissions, leakage, timing, uncertainty, storage duration, and reversal risk. AI, remote sensing, and models can strengthen MRV stages but need pathway-specific validation; registries cannot fix weak measurement or accounting rules.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
CDRクレジットの品質・永続性・二重計上リスクは、SSBJ基準や有報での気候関連開示、Scope3削減目標の達成手段として日本企業が直面する論点。J-クレジットやGXリーグのCDR取引設計にも直接示唆を与える。
In the global GX context
As ISSB, CSRD, and voluntary carbon markets formalize CDR claims, this synthesis clarifies durability, liability, and uncertainty treatment needed for credible corporate and national accounting—directly relevant to TCFD/ISSB disclosure and transition finance integrity.

📄 Abstract（原文）
Carbon dioxide removal (CDR) is becoming an important component of long-term climate mitigation. However, its climate value depends on whether removal claims reflect measurable, durable changes in atmospheric CO₂ rather than gross carbon capture or storage alone. This review evaluates monitoring, reporting, verification, and accounting (MRV/A) across biological, biochar-based, geochemical, oceanic, and engineered CDR pathways using evidence published between 2015 and 2026. The synthesis is organized around four linked functions: measuring the physical intervention, validating the net atmospheric effect, recording the resulting carbon-accounting unit, and using it in markets, corporate claims, or national inventories. The evidence shows that credible accounting requires explicit treatment of counterfactual baselines, additionality, lifecycle emissions, leakage, timing, uncertainty, storage duration, and reversal risk. Remote sensing, field sensors, geochemical measurements, lifecycle assessment, computational models, and artificial intelligence (AI) can strengthen individual stages of MRV/A, but their roles and validation requirements differ. Registries improve traceability but cannot compensate for weak measurement or accounting rules. Current policy and market frameworks also remain heterogeneous in how they treat durability, liability, uncertainty, and ownership. Future MRV/A systems should therefore link pathway-specific measurements with transparent validation rules, time-dependent accounting, interoperable records, environmental performance, social legitimacy, and clearly assigned long-term responsibility.
