本研究は、企業が脱炭素化の費用を評価するための炭素削減費用曲線の汎用モデルを開発した。欧州セメント生産者を対象にEU排出量取引制度（EU ETS）のデータで較正した結果、2023年平均のCO2価格85ユーロ/トンでは年間直接排出量を現状比約3分の1削減するインセンティブが生じる一方、100ユーロ/トンを超えると急激に削減効果が高まることが示された。
English
This paper develops a generic model for constructing carbon abatement cost curves, calibrated on European cement producers under the EU Emissions Trading System. The results show that a carbon price of €85/ton (2023 average) incentivizes about one-third reduction in annual direct emissions, with sharply increased incentives above €100/ton.

日本のGX文脈において
日本でもGXリーグや排出量取引の本格化に伴い、企業の削減費用曲線が重要になる。本モデルは日本の政策設計や企業のトランジション計画策定に応用可能である。
In the global GX context
This paper provides a practical modeling tool for corporate transition planning under carbon pricing, directly relevant to TCFD/ISSB disclosure requirements and global carbon pricing discussions.
👥 読者別の含意
🔬研究者:Abatement cost curve methodology and empirical calibration with EU ETS data offer a robust framework for further academic work on decarbonization costs.
🏢実務担当者:Corporates can use this generic model to build their own abatement cost curves for transition planning and investor communication.
🏛政策担当者:Insights on price thresholds (€85 vs €100) inform optimal carbon price levels to drive meaningful emission reductions.
📄 Abstract（原文）
Companies across industries face increasing pressure to assess the costs of decarbonizing their operations. This paper develops a generic model for constructing abatement cost curves in connection with carbon dioxide emissions. The resulting abatement cost curves provide a planning tool for companies seeking to project their decarbonization pathways and to determine optimal abatement levels in response to environmental regulations such as carbon pricing. We calibrate our model in the context of European cement producers that are required to obtain emission permits under the European Emissions Trading System. We find that a price of €85 per ton of carbon dioxide, as observed on average in 2023, incentivizes firms to reduce their annual direct emissions by about one-third relative to the status quo. Yet, this incentive increases sharply when prices rise above the benchmark of €100 per ton of carbon dioxide. Data Availability: Data used in this study are referenced in the paper and the Appendix. Data underlying the plots are provided in a supplemental material file Constructing Abatement Cost Curves - Supplementary Data.xlsx.
