ジオテキスタイルを用いたラップフェイス補強土壁のライフサイクル炭素排出量をバングラデシュの事例で評価した研究。材料選択がGWPを大きく左右し、ラップフェイス壁は鉄筋コンクリート壁の約9分の1、MSE壁の約3分の1の炭素フットプリントであることを示す。土と水のバイオエンジニアリングが従来工法より環境優位であることを定量的に裏付ける。
English
A life-cycle assessment of a geotextile wrap-faced retaining wall in Bangladesh, quantifying CO2 emissions and global warming potential. Material choice drives the benefit: the wrap-faced wall shows roughly 9x lower carbon footprint than reinforced concrete walls and 3x lower than MSE walls. It offers quantitative evidence that soil-and-water bioengineering outperforms conventional geotechnical approaches environmentally.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
建設・インフラのScope 3排出量や embodied carbon 評価に関心を持つ日本企業・建設業にとって、LCA手法と材料選択の影響を比較できる参考事例となる。ただし日本の制度・政策との直接の接続は薄い。
In the global GX context
Adds a geotechnical-engineering case to the growing embodied-carbon and infrastructure LCA literature relevant to Scope 3 and CSRD/ISSB disclosure of construction materials. It illustrates how material substitution can be quantified for climate disclosure, though it is a single-site study.

📄 Abstract（原文）
In the field of geotechnical engineering, there's a growing emphasis on climate-friendly and sustainable approaches, leading to a heightened demand for solutions that integrate technical, ecological, and aesthetic considerations. In response, life cycle assessment (LCA) has become increasingly important as a method for assessing the environmental effects of geotechnical engineering projects. This paper focuses on a soil and water soil and water bioengineering construction project that utilizes geotextile to construct a wrap-faced retaining wall. The objective is to evaluate the wall's contribution to global warming potential (GWP) by evaluating its CO2 emissions. The results highlight the significant environmental advantages of soil and water soil and water bioengineering compared to conventional approaches, especially in terms of global warming potential (GWP). The selection of materials is crucial in determining this benefit, as wrap-faced walls exhibit significantly reduced carbon footprints in comparison to conventional alternatives such as reinforced concrete (RC) walls and mechanically stabilized earth (MSE) walls. The carbon footprint of soil and water soil and water bioengineering constructions is estimated to be nine times lower than RC walls and three times lower than MSE walls, indicating a notable reduction in emissions associated with their construction and utilization. This comprehensive approach ensures a thorough examination of the environmental impact throughout the entire lifecycle of soil and water soil and water bioengineering projects, facilitating informed decision-making and sustainable practices in construction and bioengineering.
