LNGは低排出の移行燃料と位置づけられるが、施設での実測では事業者報告インベントリが実排出の59〜83%しか捕捉できていない。本レビューはコンポーネントレベルの漏洩検知から衛星監視まで、感度・時空間解像度・環境依存性・規制対応度の観点で各技術を評価する。技術は成熟しつつあるがLNG環境に特化した検証データが全スケールで不足し、標準化された検証プロトコルと規制調和の欠如が最大の課題だと指摘する。
English
LNG is promoted as a lower-emission transition fuel, yet direct measurement campaigns show operator inventories capture only 59–83% of actual fugitive methane emissions. This review assesses methane-sensing technologies from component-level leak detection to satellite surveillance against LNG facility realities, weighing sensitivity, resolution, environmental dependence, and regulatory readiness. It finds technology mature at component level but validation data LNG-specific and standardised protocols lacking, and proposes six recommendations including field validation standards, hybrid monitoring, and top-down/bottom-up reconciliation.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
LNGを移行燃料として位置づける日本のエネルギー戦略・トランジション金融にとって、メタン実測と報告の信頼性は投融資判断の前提となる。SSBJや有報でのGHG開示高度化、Scope 3算定の精緻化を進める日本企業に対し、測定ベースの検証手法と規制調和の方向性を示す。
In the global GX context
As measurement-based accountability replaces emission factors in voluntary frameworks and emerging regulation (OGMP 2.0, EU methane rules, ISSB/CSRD disclosure), this review maps which detection technologies are regulatory-ready and where validation gaps persist. It adds a cross-scale, LNG-specific lens to global methane disclosure scholarship, where upstream oil and gas dominates the evidence base.

📄 Abstract（原文）
Liquefied natural gas (LNG) is increasingly central to global energy strategy, positioned as a lower-emission transition fuel. That positioning assumes fugitive methane emissions across the LNG supply chain are well-characterised, yet direct measurement campaigns at LNG facilities have found operator-reported inventories capturing only 59–83% of actual emissions—a gap that legacy emission factors derived from upstream U.S. oil and gas facilities are poorly equipped to resolve. As measurement-based accountability replaces estimation factors in voluntary frameworks and emerging regulation, the question is which technologies are fit for purpose. This review provides a comprehensive, cross-scale assessment of methane-sensing technologies—from component-level leak detection through to satellite surveillance—evaluated against the physical and operational realities of LNG facilities. Trade-offs in sensitivity, spatial and temporal resolution, environmental dependence, and regulatory readiness are assessed to determine where each performs reliably and where it falls short. While technology is mature at the component level, validation data specific to LNG environments is scarce across all scales, and no single platform provides a complete solution. The most consequential gaps are methodological: the absence of standardised validation protocols, inadequate regulatory harmonisation, and a persistent lag between instrument capability and accepted practice. Six recommendations are proposed: standardised field validation protocols, hybrid monitoring frameworks, regulatory pathways that accommodate emerging technologies, measurement infrastructure in LNG-intensive regions, data transparency with top-down/bottom-up reconciliation, and improved monitoring coverage for intermittent and difficult-to-access fugitive emissions. Together, these define a roadmap for closing the gap between current practice and the accountability that credible LNG reporting demands.
