本研究は、ネパールの急速な都市化に伴う建設活動の増加と炭素排出問題に対処するため、低炭素建設材料の可能性を検討。セメントや鉄鋼の代替として、ジオポリマーや再生骨材、エンジニアリングウッドなどの材料を評価し、ライフサイクルベースの炭素排出量を比較。戦略的な材料代替により、構造性能を維持しつつ排出量を大幅削減できるが、コストや技術、政策面での課題が残る。
English
This thesis examines low-carbon construction materials as alternatives to conventional cement and steel in Nepal's rapid urbanization context. It evaluates materials like geopolymer binders, recycled aggregates, and engineered timber using life-cycle carbon estimation. Strategic substitution can substantially reduce embodied carbon while maintaining performance, but barriers in cost, expertise, and policy hinder adoption.

📄 Abstract（原文）
Rapid urbanization in Nepal has led to a significant increase in construction activities, resulting in rising energy consumption and carbon emissions associated with conventional construction materials such as cement, steel, and fired clay products. In the context of global climate change commitments and Nepal’s vulnerability to environmental and seismic risks, the adoption of low-carbon construction materials has become increasingly important for achieving sustainable urban development. This thesis investigates the potential role of low-carbon construction materials in reducing the environmental impact of urban development in Nepal. The study examines a range of low-carbon material alternatives, including supplementary cementitious materials, geopolymer-based binders, recycled aggregates, engineered timber, and bio-based construction materials. A comprehensive review of existing literature is conducted to evaluate their mechanical performance, durability, environmental benefits, and applicability within the Nepalese construction context. Life-cycle-based carbon emission estimation methods are employed to compare conventional materials with low-carbon alternatives, supported by mathematical formulations and scenario-based calculations relevant to urban buildings. The findings indicate that the strategic substitution of conventional materials with low-carbon alternatives can substantially reduce embodied carbon emissions while maintaining structural performance and economic feasibility. However, challenges related to material availability, cost, technical expertise, standards, and policy implementation remain significant barriers to large-scale adoption in Nepal. The study concludes by proposing practical recommendations for material selection, policy support, and future research directions to facilitate the transition toward sustainable and low-carbon urban development in Nepal.
