本研究聚焦於鞍鋼、中國中鋼和英國鋼鐵在鋼鐵冶煉過程中的可持續發展實踐。選取來自發達國家和發展中國家不同規模的鋼鐵企業，通過案例研究，探究它們在綠色技術應用、能源效率提升和碳排放控制方面的具體舉措。同時評估它們在環境、社會責任和公司治理方面的表現。研究發現，這三家公司在應用綠色技術方面採取了不同的方式。鞍鋼引進了電弧爐和節能燒結技術；中國中鋼研發了電弧爐冶煉和氫冶金技術；英國鋼鐵也計劃引進電弧爐技術。在公司治理方面，鞍鋼和中國中鋼建立了健全的治理結構，以確保可持續發展目標的有效實施。它們設立了專門的可持續發展和環境委員會，加強對環境項目和社會責任的監督。然而，英國鋼鐵在這方面有所欠缺。儘管其官網確實披露了可持續發展報告，但與另外兩家公司相比，所提供的信息略顯不足，質量和數量都稍有欠缺。最後，本文提出政策建議，以幫助鋼鐵企業在實現綠色轉型過程中降低能耗和碳排放。

This study focuses on the sustainable development practices of Ansteel, Sinosteel and British Steel in the steel smelting process. Selecting steel companies from both developed and developing countries with different scales, through case studies, this study explores their specific measures in green technology application, energy efficiency improvement and carbon emission control. It also evaluates their performance in environmental, social responsibility and corporate governance. Research has found that the three companies have taken different approaches in applying green technology. Ansteel has introduced electric arc furnace and energy-saving sintering technology; Sinosteel developed electric arc furnace smelting and hydrogen metallurgy technology; British Steel is also planning to introduce electric arc furnace technology. In terms of corporate governance, Ansteel and Sinosteel have established robust governance structures to ensure the effective implementation of sustainability goals. They have set up dedicated sustainability and environmental committees to strengthen oversight of environmental projects and social responsibilities. However, British Steel is somewhat lacking in this regard. Although its official website does disclose sustainability reports, the information provided is somewhat insufficient compared to the other two companies, and both its quality and quantity are slightly deficient. Finally, this paper puts forward policy suggestions to help steel enterprises reduce energy consumption and carbon emissions in the process of realizing green transformation.
