本研究は台湾の37の集合住宅を対象に、ライフサイクル全体のエンボディドカーボン強度（ECI）を評価した。ECIは420.60〜624.72 kg CO2e/m2-60yrの範囲で、平均502.45 kg CO2e/m2-60yrであった。製造・輸送段階（A1-A4）が全体の約82.9%を占め、特に主要構造が約58.6%を占めることが判明した。この結果は、建設部門の炭素排出削減政策に資するベンチマークを提供する。

This study benchmarks Embodied Carbon Intensity (ECI) for residential buildings using data from 37 multi-family buildings in Taiwan. The lifecycle ECI ranges from 420.60 to 624.72 kg CO2e/m2-60yr, with an average of 502.45. Manufacturing and transport stages (A1-A4) account for 82.9% of emissions, and the main structure contributes 58.6%. These localized benchmarks support evidence-based building carbon policies.

日本のGX文脈において
台湾の集合住宅のエンボディドカーボンベンチマークを提供する本論文は、日本でも同様のベンチマーク設定が求められる中で参考となる。特に、建設段階（A1-A4）が全体の約82.9%を占める点は、日本の建設業界におけるサプライチェーン排出量削減にも示唆を与える。
In the global GX context
This paper provides empirical benchmarks for embodied carbon in residential buildings in Taiwan, which can inform similar efforts in other Asian countries, including Japan. The finding that manufacturing and transport stages (A1-A4) account for 82.9% of lifecycle emissions highlights the need for supply chain decarbonization in the construction sector.

📄 Abstract（原文）
While embodied carbon (EC) research in buildings has been extensively conducted over the past decades, practical benchmarking of Embodied Carbon Intensity (ECI) remains relatively limited compared to the well-established Energy Use Intensity (EUI) standards in building policies. This gap between academic research and practical implementation underscores the need for more comprehensive ECI benchmarking studies to support evidence-based policymaking. Despite global advancements in empirical case studies and benchmarking for embodied carbon, there remains a significant absence of localized benchmarks that accurately reflect construction practices specific to various regions. In this study, we conducted a benchmarking project to assess the Embodied Carbon Intensity (ECI) of residential buildings by analyzing data from 37 multi-family residential buildings in Taiwan. The results show that ECI over the entire life cycle ranges approximately from 420.60 to 624.72 (kg CO2e/m2-60yr), with an average of 502.45 (kg CO2e/m2-60yr) and a standard deviation of 55.71 (kg CO2e/m2•60yr). Furthermore, among all life cycle stages, the manufacturing and transportation stages (A1-A4) account for the highest proportion at approximately 82.90%. Among sub-projects, the main structure accounts for the highest proportion at approximately 58.56%.
