日本語
2011〜2025年のScopus論文285件を対象に、建設資材のエンボディドカーボン（EC）と脱炭素化研究を計量書誌分析した研究。2016年以降に出版が急増し、LCA・EC定量化・脱炭素プロセスが主要テーマである一方、手法の不一致や最適化研究・途上国研究の不足が顕著なギャップとして示された。低炭素資材の普及と標準的な炭素評価の統合に向けた提言を行う。
English
A bibliometric analysis of 285 Scopus papers (2011–2025) on embodied carbon (EC) and decarbonization in building materials. Publications surged after 2016, with LCA, EC quantification, and decarbonization dominating, while circular economy and data-driven decision-making are emerging. Key gaps include methodological inconsistency, scarce optimization-focused work, and underrepresentation of developing countries.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
建設セクターのScope 3（カテゴリ1・2）排出はSSBJ基準や有報のサステナビリティ開示で重要性が増しており、資材のエンボディドカーボン評価手法の標準化は日本企業の開示対応に直結する。LCA手法の不一致はサプライチェーン排出量算定の実務課題とも符合する。
In the global GX context
Embodied carbon in construction is central to Scope 3 Category 1/2 accounting under ISSB/CSRD and the growing focus on whole-life carbon in building codes (EU EPBD, etc.). This review maps methodological fragmentation and gaps that global disclosure frameworks must resolve to make material-level carbon data comparable and auditable.
👥 読者別の含意
🔬研究者:建設資材EC研究の全体像と未開拓領域（最適化・途上国事例）を把握できる。
🏢実務担当者:サプライチェーン排出量算定や低炭素資材調達の際、LCA手法のばらつきと標準化の必要性を理解する材料になる。
🏛政策担当者:建設分野の炭素評価標準化と途上国支援の政策設計に示唆を与える。
📄 Abstract（原文）
Building materials account for a significant percentage of embodied carbon (EC) across construction life cycles, making the industry a significant contributor to global greenhouse gas emissions. Studies on EC and decarbonization continue to be dispersed among disciplines, techniques, and regional settings despite increased academic interest, which limits their policy and practical usefulness, especially in developing countries. Using Scopus peer-reviewed publications from 2011 to 2025, this study provides a bibliometric analysis of EC and decarbonization in building materials using 285 studies to identify publication trends, subject areas, and top journals while keyword co-occurrence networks generated using VOSviewer software version 1.6.20 identified theme advancement and thematic evolution following PRISMA procedures. The qualitative synthesis of the assessing methodological landscape of embodied carbon analysis was conducted on nine (9) evaluated studies. Results show a sharp increase in publications after 2016, with engineering, environmental science, and energy disciplines dominating. While the growing fields include circular economy practices and data-driven decision-making, life cycle assessment, EC quantification, and decarbonization procedures are important topics. However, there are significant inconsistencies in methods and a lack of optimization-focused studies and investigations from developing countries and regions, signifying important gaps in low-carbon construction practices. Key research gaps were identified, and recommendations were provided to enhance the adoption of low-carbon materials and integrate standard carbon assessment.
