本研究は、建築材料（特にカリフォルニア州のセメント・コンクリート）の具体化炭素を迅速に評価するツールREDuCEを開発した。ユーザーは生産技術、輸送手段、燃料源、地域電力構成をカスタマイズでき、低炭素生産経路や材料効率向上により最大80%の排出削減が可能である。事例研究では、材料使用強度の低減が主要な削減要因であることが示された。
English
This paper presents the REDuCE tool for rapid embodied carbon assessment of building materials, focusing on cement and concrete in California. It allows users to customize supply chains (production technology, transport, fuel, electricity mix) and explore mitigation options (low-carbon production, material efficiency, transport modes). A case study shows up to 80% emission savings, primarily from reduced material use intensity. The tool expands LCA capabilities for stakeholders to assess customized supply chains.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では、建設分野のカーボンニュートラルに向けて、建材の具体化炭素評価が重要視されている。本ツールはサプライチェーンカスタマイズが可能であり、日本のサプライヤー評価やSSBJ対応に応用可能。ただし、カリフォルニア向けのため、日本の電力構成や輸送距離に調整が必要。
In the global GX context
Globally, embodied carbon assessment is increasingly mandated (e.g., ISO 14067, EN 15804). This tool offers a customizable LCA approach that could inform similar tools for other regions, including compliance with ISSB and CSRD. The focus on material efficiency and low-carbon pathways is widely applicable.

📄 Abstract（原文）
Embodied carbon limits within building materials are a driving factor in global trade, generating new research and analysis tools in industry. These product assessments, which require utilizing life-cycle assessment (LCA) across broad supply chains, can be expensive, time and data-intensive, and subject to significant variations. Existing methods and tools, such as specific environmental product declarations, typically do not capture these variations and dynamics in supply and manufacturing. Moreover, models and tools must enable stakeholders to assess customized supply chains and future scenarios. In this study, we present the Rapid Embodied Carbon Assessment and Target-setting for Emissions-intensive Materials (REDuCE) tool for building materials. We developed a tool that allows users to select production technologies, transportation mode and distances, concrete carbonation, fuel sources, and regional electricity mixes to supply customization for cement and concrete produced and consumed in California. We generated and integrated a material demand model using residential building stock projections. We provide the user with a wide range of mitigation alternatives through low-carbon production pathways, material use efficiency, transportation modes, and projected electricity grid mixes. In a case study application through four mitigation scenarios, we find emission savings up to 80% by maximizing user mitigation alternatives, primarily driven by reductions in material use intensities. This work represents a foundation for expanding LCA and embodied carbon tools to better enable stakeholders to rapidly and accurately assess customized supply chains while meeting trade requirements.
