現在の炭素会計はCO2注入を永久除去とみなすが、破砕性貯留層では51.7%が10年後も移動性を持つ。本論文は二値会計に代わり、滞留時間と相安定性に基づく4つの封じ込め区分、時間加重正味炭素貯留指標、3層の世代間責任メカニズムを提案。中国の大規模展開を前に、時間認識型ガバナンスの確立を訴える。
English
Current carbon accounting equates CO2 injection with permanent removal, but data from fractured reservoirs show 51.7% remains mobile after 10 years. This paper proposes replacing binary accounting with four containment regimes based on residence time and phase stability, a Time-Weighted Net Carbon Storage metric, and a three-tiered intergenerational liability mechanism. It highlights China's gigatonne-scale deployment as a critical window for establishing time-aware governance.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本もGX政策でCCUSを推進中。本論文の指摘は、永久貯留の前提を再考し、長期隔離を保証するガバナンス設計が必要であることを示唆。日本のCCSプロジェクト（苫小牧など）の評価や規制に直接的な示唆を与える。
In the global GX context
Globally, CCUS deployment is accelerating under net-zero targets, but carbon accounting standards (IPCC, voluntary markets) assume permanent storage. This paper exposes a critical temporal gap and proposes novel metrics and liability mechanisms, with implications for climate disclosure (TCFD/ISSB) and transition finance.
👥 読者別の含意
🔬研究者:GX researchers should note the empirical evidence on CO2 mobility and the proposed Time-Weighted Net Carbon Storage metric as a step toward accurate carbon removal accounting.
🏢実務担当者:Corporate sustainability teams involved in CCUS should consider the risk of carbon leakage over decades and the potential liability implications of the proposed three-tiered mechanism.
🏛政策担当者:Policymakers designing CCUS regulatory frameworks should incorporate time-based containment regimes and intergenerational liability to avoid locking in suboptimal infrastructure.
📄 Abstract（原文）
Current carbon accounting equates CO 2 injection with permanent removal, an assumption that analysis of fractured unconventional reservoirs contradicts: 51.7% of injected carbon remains mobile after 10 years. This temporal misalignment rewards decade-scale performance while century-scale isolation is required, risking the institutionalization of carbon leakage within climate infrastructure. Binary accounting should be replaced by four containment regimes distinguished by residence time and phase stability, operationalized through a Time-Weighted Net Carbon Storage metric and a three-tiered intergenerational liability mechanism. China’s ongoing gigatonne-scale deployment provides a critical window to establish these time-aware governance precedents before suboptimal infrastructure becomes locked in.
