インド・ハイデラバードのコンクリート橋の建設段階を対象に、Open LCAとEcoinventデータベースを用いてLCAを実施。セメントが最大の環境負荷（炭素フットプリント約10,105,721 m²a）で、基礎部材が最も高い負荷を示した。低環境負荷材料への代替やリサイクル骨材の活用を提案している。
English
This study conducts a life cycle assessment of a concrete bridge construction in Hyderabad using Open LCA and Ecoinvent. Cement is the most environmentally burdensome material, contributing a carbon footprint of about 10,105,721 m²a, and the foundation has the highest impact among components. Recommendations include using supplementary cementitious materials and recycled aggregates to reduce environmental footprints.

📄 Abstract（原文）
This study evaluates the environmental impacts associated with the construction phase of a concrete bridge in Hyderabad using Open LCA software and the Ecoinvent v3.9.1 database. The analysis covers major structural components like foundation, piers, abutments, deck slab, crash barrier, wearing coat, return wall, and approach slab and key construction materials such as cement, sand, aggregates, and reinforced steel. Life Cycle Impact Assessment was conducted using ReCiPe Midpoint v1.03 (H), Eco-Indicator 99, and Ecological Footprint methods to quantify impacts across categories such as global warming potential, acidification, and ozone depletion. Results indicate that cement is the most environmentally burdensome material, contributing approximately 10,105,721 m²a of carbon footprint, due to its energy-intensive manufacturing process. Aggregates recorded the lowest impact (0.0015 kg CFC eq) due to its minimal processing requirements. Among structure components, the foundation exhibited the highest environmental load, with carbon footprint of 4,846,171 m²a, primarily from its large concrete and steel volumes, while the approach slab had the lowest impact. The findings highlight the need for sustainable material selection and design strategies during construction to reduce environmental footprints. Recommendations include substituting high impact materials with supplementary cementitious materials and exploring recycled aggregates for future projects.
