本論文は、構造用コンクリートの需要側（設計者、施工者、構造物所有者）のCO2削減貢献を定量化することを目的とする。GCCAのネットゼロロードマップと日本の国立環境研究所のデータを分析し、供給側と需要側の削減分担を明確化した。さらに、コンクリートと鉄筋のCO2削減量を推定し、fibメンバーが目指すべき指標を提案する。これにより、各組織がステークホルダーに示す削減効果を可視化し、低炭素技術の開発と実装を促進する。
English
This paper quantifies the contribution of the demand side (designers, contractors, owners) to CO2 reduction in structural concrete. Analyzing GCCA's net-zero roadmap and Japanese NIES data, it clarifies the reduction sharing between supply and demand sides. It estimates CO2 reductions for concrete and reinforcing steel and proposes indicators for fib members, enabling visualization of reduction effects to stakeholders and motivating low-carbon technology development.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではSSBJ開示やサプライチェーン排出量算定が進む中、建設分野の需要側の削減貢献を可視化する本提案は、ゼネコンや設計事務所のScope 3対応や投資家向け開示に有用である。また、GCCAロードマップとの整合は国際的な整合性確保にも寄与する。
In the global GX context
Globally, as ISSB and CSRD push for supply-chain emissions disclosure, this paper offers a framework for demand-side actors in construction to quantify and communicate their CO2 reduction contributions. It aligns with GCCA's net-zero roadmap, providing a basis for harmonized indicators across the concrete value chain.

📄 Abstract（原文）
Abstract The CO 2 emitted by concrete, the main material used in structural concrete, is emitted in various processes in its supply chain. Therefore, reducing CO 2 emissions is not just a matter for the supply side, namely cement and concrete manufacturers, but also concerns the demand side including designers, contractors, and the structure owners. However, how much of the reduction in CO 2 emissions should be shared between the supply and demand sides? In this article, the net zero roadmap for concrete by 2050 published by the GCCA, a Global Cement and Concrete Association, and the National Institute for Environmental Studies in Japan, is analyzed to clarify the contribution of supply and demand sides to the reduction of CO 2 emissions. Furthermore, estimates have been made of the reduction in CO 2 emissions for concrete, which is the main material used in structural concrete, and for reinforcing steel, although data is insufficient. And a proposal is made for the indicators that each member of fib should aim for. This will make it possible to visualize the CO 2 emissions reduction effects that each member organization can show to stakeholders and motivate the development and implementation of new technologies that contribute to low‐carbon and decarbonization.
