本論文は、冶金産業の脱炭素モデルをマクロ地域別に類型化し、その選択要因を分析する。北欧の水素電力モデル、グローバル多角化モデル、東アジア進化モデル、ロシア移行モデルの4つを特定し、エネルギーコスト、スクラップ・高品位鉄鉱石の入手可能性、資本コスト、炭素規制、販売市場構造が経路選択を左右すると結論付ける。普遍的で経済的に最適な脱炭素経路は存在せず、ロシアには天然ガス・原子力・水力に基づく段階的移行モデルを提唱する。
English
This paper identifies and systematizes macro-regional differences in decarbonization models for the metallurgical industry, analyzing factors shaping technological and investment pathways. Four models are distinguished: Northern European hydrogen-electric, globally diversified, East Asian evolutionary, and Russian transitional. The study concludes there is no universal optimal pathway, and for Russia, a phased transitional model based on natural gas, nuclear, and hydropower is proposed.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の鉄鋼業界は水素還元やCCUSなど複数の経路を検討しており、本論文の地域別比較は日本企業の戦略選択に示唆を与える。特に、資源制約や炭素規制の違いが経路選択に与える影響は、日本の政策立案や国際競争力の観点で参考になる。
In the global GX context
This paper contributes to global decarbonization scholarship by comparing regional models in the steel sector, highlighting that no single pathway is universally optimal. It offers insights for international investors and policymakers assessing the feasibility of hydrogen-based steelmaking versus other transitional approaches, particularly in emerging economies.
👥 読者別の含意
🔬研究者:Provides a comparative framework for analyzing regional decarbonization pathways in heavy industry, useful for further empirical studies.
🏢実務担当者:Offers insights into how regional factors like energy costs and carbon regulation shape technology choices, informing corporate strategy.
🏛政策担当者:Highlights the need for region-specific policies rather than one-size-fits-all approaches to industrial decarbonization.
📄 Abstract（原文）
The purpose of the article is to identify and systematize macro-regional differences in decarbonization models of the metallurgical industry and to determine the factors shaping the choice of technological and investment pathways for the green transition. The research methodology combines comparative sectoral analysis, benchmarking of corporate climate strategies, elements of PESTEL analysis, comparison of resource endowments, and analysis of financial and economic parameters of low-carbon projects. The empirical base includes materials of the World Steel Association and international organizations, regulatory documents, as well as public reports of SSAB, ArcelorMittal, China Baowu Group and PJSC Severstal. Four conditional macro-regional decarbonization models are identified: the Northern European hydrogen-electric model, the globally diversified model, the East Asian evolutionary model and the Russian transitional model. The differences between them are shown to be determined by territorially localized factors: the cost and structure of the energy balance, availability of ferrous scrap and high-grade iron ore, cost of capital, carbon regulation regimes and the structure of sales markets. The study concludes that there is no universal economically optimal decarbonization pathway for the metallurgical industry. For the Russian metallurgical sector, a phased transitional model based on natural gas, nuclear and hydropower, higher resource efficiency and a national carbon-footprint verification system is substantiated.
