中国のセメント産業における6つの脱炭素技術を、ライフサイクルアセスメントと多属性意思決定モデル（AHP-エントロピー-TOPSIS）で比較評価。バイオマス燃料代替と高粉砕効率が環境・経済面で最も優れたパフォーマンスを示し、代替原料や炭素回収技術はトレードオフを伴うことを定量的に明らかにした。
English
This study evaluates six decarbonization technologies for Chinese cement production using LCA and a multi-attribute decision-making model. Biomass fuel substitution and high grinding efficiency achieve the best synergistic reduction of pollution and carbon emissions with favorable economic performance, while alternative raw materials and carbon capture show significant trade-offs. The findings provide quantitative guidance for prioritizing and combining strategies in the cement industry.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でもセメント産業はGX（グリーントランスフォーメーション）の重要分野であり、SSBJ開示やトランジション・ファイナンスの文脈で脱炭素技術の比較評価が求められている。本研究のフレームワークは日本企業の技術選定や投資判断に応用可能だが、中国固有のデータに基づくため直接的な適用には注意が必要。
In the global GX context
This paper contributes to the global literature on industrial decarbonization pathways, particularly for hard-to-abate sectors like cement. The life cycle assessment and multi-criteria decision analysis approach is directly relevant to disclosure frameworks such as TCFD and ISSB, which require evidence-based climate transition planning. The empirical evidence from China, the world's largest cement producer, offers valuable benchmarks for global decarbonization efforts.

📄 Abstract（原文）
Rapid urbanization and escalating demands for pollution and carbon reduction pose significant challenges to the cement industry in China, characterized by high energy consumption and emissions. However, a multidimensional framework to assess the synergies and trade-offs between environmental, carbon, and economic effects for various decarbonization technologies in cement production is still lacking. Here, six application scenarios of new suspension preheater dry process cement production were developed and evaluated using a life cycle assessment (LCA) framework to quantify environmental impacts, synergistic reduction of pollution and carbon emissions (SRPC), and economic performance. A multi-attribute decision-making model, Analytic Hierarchy Process–entropy–TOPSIS (AHP–entropy–TOPSIS), was applied to assess environmental–economic trade-offs. The results indicate that biomass fuel substitution and high grinding efficiency achieved the best SRPC and environmental–economic trade-off scores (Snorm: 0.17–0.22). Alternative raw materials moderately reduced carbon but increased pollutant emissions and economic uncertainty (Snorm: 0.14–0.20). Mono-ethanolamine absorption and calcium looping provided substantial carbon reduction but weaker overall performance due to environmental trade-offs and higher costs (Snorm: 0.12–0.16). These findings provide quantitative guidance for prioritizing and combining decarbonization strategies to support the green transition and sustainable development of the cement industry.
