CCUS拡大に伴い、貯留監視・保証・許認可・閉鎖後管理を支える公開環境エビデンスの必要性が高まっている。本研究は23のエビデンスモジュールと1110件のプロジェクト記録を収集し、18×99の寄与マトリクスを構築した。文書化された正例は6.23%に留まり、多くの次元が単一モジュールのみで支持されるなど、公開エビデンス基盤の薄さと偏在を定量的に示した。
English
As CCUS expands, publicly accessible environmental evidence is needed for storage monitoring, assurance, permitting, and post-closure oversight. The authors assembled 23 evidence modules and 1,110 project records into an 18×99 contribution matrix, finding only 6.23% documented-positive cells and many dimensions supported by a single module. The study quantifies gaps and geographic disparities in the public evidence base for CO2 storage.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本はCCS事業化を加速しており、貯留監視・保証・許認可のエビデンス整備は経済産業省やJOGMECの実務に直結する。公開エビデンスの偏在は国内CCSの社会的受容や規制設計にも示唆を与える。
In the global GX context
This work maps the public evidence base for CO2 storage monitoring and assurance, directly relevant to global CCUS deployment, permitting, and post-closure oversight. It highlights gaps that affect regulatory frameworks and disclosure expectations for storage projects under emerging climate regimes.

📄 Abstract（原文）
Rapid expansion of carbon capture, utilization, and storage (CCUS) is increasing the need for publicly accessible environmental evidence that can support monitoring design, storage assurance, permitting, and post-closure oversight across diverse storage settings. Public records remain dispersed across controlled-release experiments, operating projects, natural analogues, incident datasets, project databases, and regulatory documents. We assembled a purposively curated corpus of 23 evidence modules and 1110 project records. Of these, 18 modules contained harmonized contribution coding for the canonical matrix, while five served defined non-matrix roles. The 18 × 99 matrix contained 111 documented-positive cells (6.23%); 95 of 99 raw dimensions were represented, but 80 occurred in only one module. The 86 retained dimensions were grouped into 42 parent concepts, of which 13 were supported by one substantive module, 29 by at least two, and 15 by at least three. The single-module count ranged from 11 to 17 across threshold and QICS checks, and external inclusion of Aquistore reduced it to 10. Seven jurisdictions were above the country-screen medians for both deployment pressure and documented deficit intensity, while only Qatar, Saudi Arabia, and the United Arab Emirates remained in that archetype throughout the full evidence-regulatory weight scan. The screen represents monitoring and disclosure workload, not leakage risk. Transferability was constrained by geological setting, duration, wellbore and pathway context, baseline design, analytical QA/QC, and data accessibility. Priority actions are comparable measurements across contrasting settings, longer public time series, and reporting systems that preserve contextual and methodological information for reuse.
