本論文は、IMO CII、FuelEU Maritime、EU ETSの規制会計フレームワークを用いて、海運におけるメタノールの脱炭素効果を評価する。2024年のTHETIS-MRVデータを分析し、化石メタノールはVLSFOやLNGより高コストで高炭素強度である一方、低GHGメタノールはFuelEUバランスを大幅に改善できることを示す。また、e-メタノールの競争力はコンプライアンス戦略に依存し、2025年のEU ETS曝露は49億ユーロに上る。
English
This paper evaluates methanol's decarbonization value under IMO CII, FuelEU Maritime, and EU ETS regulatory accounting frameworks. Analyzing 2024 THETIS-MRV data, it finds fossil methanol is costlier and more carbon-intensive than VLSFO and LNG, while low-GHG methanol can significantly improve FuelEU balance. E-methanol competitiveness depends on compliance strategy, with illustrative 2025 EU ETS exposure of EUR 4.90 billion.

📄 Abstract（原文）
<title>Abstract</title> <p>Marine methanol is often discussed as a decarbonisation option, but its value depends on the regulatory account in which it is measured. This paper develops a regulatory-accounting screen for methanol under the IMO Carbon Intensity Indicator, FuelEU Maritime and the EU Emissions Trading System, and applies it to public 2024 THETIS-MRV data. The framework separates physical combustion factors, assigned CII factors, FuelEU well-to-wake intensity and EU ETS surrender factors rather than collapsing them into one emissions number. Under the declared central scenario, fossil grey methanol fails as a decarbonisation pathway because it has both higher delivered fuel cost and higher lifecycle intensity than VLSFO and low-slip diesel-cycle LNG. Illustrative qualifying-pathway low-GHG methanol can nevertheless create large FuelEU balance improvements. A reproducible annual e-methanol screen shows that parity remains highly sensitive to compliance strategy, certificate treatment and route scope: restrictive full-substitution thresholds are far lower than exact-compliance minimum-blend thresholds in 2033, but the two converge as FuelEU tightens toward 2050. The MRV application retains 12,958 ship-years, with 147.14 MtCO2 verified emissions and EUR 4.90 billion illustrative 2025 EU ETS exposure. Public MRV data support exposure targeting, not ship-level FuelEU or CII reconstruction.</p>
