本論文は、鉄鋼産業団地の炭素排出量算定のためのプロセスエネルギーフローに基づく計算システムを構築。排出源を燃料燃焼、工業プロセス、購入電力、購入熱、炭素固定製品の5種類に分類し、中国東北部の年産800万トン一貫製鉄所を事例に2022～2025年の排出構造を分析した。コークス製造と製鉄工程が全体の約70%を占め、購入電力の排出が増加傾向にあることを明らかにした。エネルギーシステム再編、プロセス改革、デジタル駆動型ガバナンス、生態炭素吸収源強化の4次元の移行経路を提案している。
English
This paper develops a process-energy-flow-based carbon emission accounting system for steel industrial parks, categorizing sources into fuel combustion, industrial processes, purchased electricity and heat, and carbon-sequestering products. Using an 8-million-ton integrated steel complex in Northeast China as a case study (2022-2025), it finds coking and ironmaking contribute ~70% of emissions, while purchased electricity emissions rise annually. A four-dimensional transformation pathway (energy restructuring, process reengineering, digital governance, ecological sinks) is proposed for near-zero carbon transition.

日本のGX文脈において
日本の鉄鋼業界（日本製鉄など）も同様の炭素会計・削減課題に直面しており、本論文のプロセスエネルギーフロー法は国内産業団地に応用可能。特にSSBJ基準や有報での排出量開示が進む中、算出手法の標準化に示唆を与える。
In the global GX context
This paper contributes to global industrial decarbonization literature by providing a detailed carbon accounting methodology for steel industrial parks, a hard-to-abate sector. The findings on emission structure (coking/ironmaking dominance) and the proposed four-dimensional pathway are relevant for countries pursuing near-zero carbon strategies, aligning with TCFD/ISSB disclosure frameworks for transition planning.

📄 Abstract（原文）
Abstract Industrial parks serve as the primary vehicle for the clustered development of the steel industry, and the scientific calculation of carbon emissions forms the foundation for formulating precise reduction strategies. Addressing the issues of inconsistent carbon emission calculation methods and unclear reduction pathways in steel industrial parks, this paper first establishes a carbon emission calculation system for steel industrial parks based on process-energy flows. Emission sources are categorized into five major types: fuel combustion, industrial processes, purchased electricity, purchased heat, and carbon-sequestering products. Using an 8-million-ton-per-year integrated steel complex in Northeast China as a case study, the carbon emission structure characteristics and intensity indicators for the period 2022–2025 are calculated and analyzed. The study reveals that the park’s total carbon emissions show a gradual downward trend, with coking and ironmaking processes contributing approximately 70% of emissions, while emissions from purchased electricity have increased annually. Based on these findings, a four-dimensional transformation implementation pathway is proposed, encompassing energy system restructuring, process reengineering, digital intelligence-driven governance, and ecological carbon sink enhancement. This framework provides a systematic reference for achieving near-zero carbon transformation in steel industrial parks.
