本研究は、タイの住宅地開発におけるアスファルトコンクリート道路と統合排水システムの建設に伴う体化炭素を定量化した。ケーススタディの結果、全排出量の70%以上がアスファルト舗装に起因し、資源生産と輸送が排出の95%以上を占めた。この結果は、タイの建設業界における排出削減の優先順位付けに役立つベンチマークを提供する。
English
This study quantifies embodied carbon from constructing asphalt concrete roads and integrated drainage systems in Thai housing estates. The case study finds asphalt pavement contributes over 70% of total emissions, and resource production and transportation account for 95.48% of emissions. The results provide benchmarks for prioritizing emission reduction strategies in Thai construction.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
本論文はタイの事例だが、体化炭素評価の手法は日本の建設業界でも応用可能。特に、資材選定や施工方法の見直しによる排出削減の優先順位付けに示唆を与える。日本の建設業界では、2025年度以降のカーボンニュートラルに向けた取り組みが加速しており、本研究成果は参考となる。
In the global GX context
While set in Thailand, the embodied carbon assessment methodology is transferable to other contexts. The study provides a detailed work-package level breakdown that can help identify emission hotspots. For global scholars and practitioners, it offers benchmarks from a developing country context, which are often lacking in the literature.

📄 Abstract（原文）
This study quantifies the embodied carbon associated with the construction of asphalt concrete roads and integrated drainage systems commonly used in Thai housing estate developments. Using a case study approach, the research involved detailed data collection and analysis of work quantities, construction activities, and resource use, with emission factors primarily derived from Thai databases to ensure contextual relevance. The assessment applied a life cycle assessment (LCA) framework in accordance with BS EN 15978:2011, covering Modules A1–A5 (from raw material supply to on-site construction). The case study project—a 307 m asphalt concrete road with a 6.70 m carriageway and an integrated drainage system of equal length—generated total embodied carbon emissions of 198,466.532 kgCO2e, equivalent to 646.471 kgCO2e per meter of road. These values can serve as benchmarks for the Thai construction industry to support design decisions and construction control aimed at reducing environmental impacts. Work package-level analysis identified asphalt pavement laying as the dominant emission source, accounting for over 70% of total emissions, while concrete-related work packages—including gutter concrete, lean concrete for reinforced concrete (RC) pipes, manhole concrete, and RC pipe installation—collectively contributed nearly 21%. Overall, emissions were dominated by resource production and transportation (95.48%), whereas on-site construction activities accounted for a comparatively small share. Asphalt and ready-mixed concrete were the most influential materials due to their high emission factors and large quantities used. The findings provide practical insights to help stakeholders prioritize and implement effective embodied carbon reduction strategies in future housing estate infrastructure projects.
