鉄鋼業は世界のCO2排出量の7-9%を占め、本論文はEUのETSとCBAM、米国の補助金モデル、中国の国家主導戦略を比較し、強力な気候政策が低炭素技術への投資を促進することを示す。EUの炭素価格と国境調整の組み合わせが最も一貫したインセンティブを提供するが、中国の計画的な投資も技術変化を加速できる。米国では炭素会計と投資インセンティブを組み合わせたハイブリッドモデルが提案される。
English
Steel accounts for 7-9% of global CO2 emissions. This paper compares the EU's ETS and CBAM, the US subsidy model, and China's state-led strategy, showing that stronger climate policies drive consistent investment in low-carbon technologies. The EU's carbon pricing plus border adjustments offer the most coherent incentives, while China's coordinated planning can also accelerate change. A hybrid model for the US combining carbon accountability with investment incentives is proposed.

📄 Abstract（原文）
Steel manufacturing is an important pillar of the world economy, accounting for about 7-9% of annual carbon dioxide emissions. This paper discusses the role of climate policy in providing emission reductions in the steel sector without compromising industrial competitiveness and carbon leakage. It discusses the EU’s Emissions Trading System (ETS) and the Carbon Border Adjustment Mechanism (CBAM) within the framework of the USA’s subsidy-based model and China’s state-led industrial strategy. This paper uses comparative policy analysis and case studies of ArcelorMittal, Nucor, U.S. Steel, and China Baowu Steel Group to show that companies operating in environments with stronger climate policies are more likely to invest consistently in low-carbon technologies. The EU’s combination of carbon pricing and border adjustments provides the strongest and most coherent incentives, but China’s coordinated industrial planning shows that state-led investment can also accelerate technological change. In the United States, a hybrid model that combines carbon accountability with continuous investment incentives could be applied to accelerate steel decarbonization. Rising carbon dioxide (CO2) emissions present a significant global challenge, increasing pressure on countries to decarbonize carbon-intensive industries.
