本研究は変圧器のライフサイクルアセスメントに基づく炭素フットプリント（CF）モデルを構築し、異なる定格電圧の変圧器のCFを定量化。操業段階がCFの主要因であり、原材料段階では鋼材と銅が主な排出源であることを示した。8つの主要影響因子を特定し、総損失を10%削減するとCFが約10%低下することを発見。さらに、多因子削減経路の有効性を検証し、全定格電圧で平均9.75%の削減が可能であることを示した。
English
This study constructs a life cycle assessment (LCA)-based carbon footprint (CF) model for transformers, quantifying CF at different rated voltages. The operation stage dominates CF, with electricity as the main source; steel and copper dominate raw-material stage. Eight key factors are identified, and a 10% reduction in total losses reduces CF by ~10%. A multi-factor reduction pathway achieves 9.75% CF reduction across all voltages, supporting low-carbon transition of power systems.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でも変圧器は電力系統に広く利用されており、LCAに基づく炭素排出評価は機器製造業者のカーボンフットプリント開示やSSBJ対応に役立つ可能性がある。ただし本研究は中国のデータに基づくため、日本への適用には系統電源構成の違いを考慮する必要がある。
In the global GX context
Globally, transformers are critical for electricity infrastructure, and this LCA-based carbon footprint analysis provides a replicable methodology for equipment-level decarbonization. The findings highlight energy efficiency and clean grid integration as key levers, relevant for TCFD/ISSB reporting on supply chain emissions and for policy frameworks like EU Ecodesign.

📄 Abstract（原文）
Transformers are key devices in the new electricity system, and the entire life cycle is associated with a considerable resource consumption and carbon footprint (CF). Understanding CF is essential for accelerating the low-carbon transition of the industry. Therefore, a systematic CF model for transformers is constructed in this study based on life cycle assessment (LCA). The results indicate that the operation stage is the overwhelmingly dominant phase for CF of transformer, with electricity acting as the main carbon source. The CF at the raw-material stage mainly originates from steel and copper. Through analysis, eight key impact factors were identified, leading to the formulation of three-dimensional carbon reduction pathways. It was observed that a 10% reduction in total losses of a transformer results in an approximate 10% decline in CF. At the same time, the transition of the electricity grid to clean energy helps reduce CF during operation. In addition, the effectiveness of a multi-factor carbon reduction pathway was examined. The results showed that, under this integrated pathway, the CF across all transformer rated voltages could be reduced by 9.75%. Based on this, a system pathway centered on enhancing operational energy efficiency is proposed, supported by green materials and processes, and coordinated through smart operation and maintenance, and circular recycling. This provides quantitative evidence and decision support for the green transition of transformers, contributing to the broader goals of sustainability development in electricity system.
