本論文は、5つの統合評価モデルを用いて、多様な二酸化炭素除去（CDR）オプションのコスト依存ポテンシャルを供給曲線として提示。炭素価格400$/tCO2で2050年に2.6-9.7 GtCO2/年、2100年に10.3-20.9 GtCO2/年のグローバルCDRポテンシャルを示し、地中貯留を伴うオプションが支配的。長期戦略目標達成には十分な技術的ポテンシャルがあるが、政策的・財政的支援が必要。
English
Using five Integrated Assessment Models, this paper presents supply curves for various carbon dioxide removal (CDR) options at different carbon prices. At 400 $/tCO2, global CDR potential reaches 2.6-9.7 GtCO2/yr in 2050 and 10.3-20.9 GtCO2/yr in 2100, with geological storage options dominating. The results indicate sufficient technical potential to meet long-term strategy targets, but substantial policy and financial support is required.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本はCDR技術（DACCS、BECCS等）の研究開発を推進中。本論文の供給曲線は、日本のカーボンプライシングや長期脱炭素戦略の策定に有用なベンチマークを提供。特に、コストとポテンシャルのモデル間比較は、日本が国際的なCDR展開を検討する際の参考となる。
In the global GX context
This multi-model assessment provides critical benchmarks for global CDR potential across price levels, informing policy on carbon pricing and technology deployment. The comparison of DACCS vs BECCS variability is especially relevant for countries designing CDR portfolios under TCFD/ISSB-aligned climate strategies.
👥 読者別の含意
🔬研究者:Provides model intercomparison of CDR supply curves, useful for IAM validation and scenario development.
🏢実務担当者:Offers cost benchmarks for CDR technologies that inform procurement and investment decisions.
🏛政策担当者:Demonstrates that global CDR potential is sufficient for LTS targets but requires strong policy support, highlighting the need for carbon pricing and R&D incentives.
📄 Abstract（原文）
Carbon dioxide removal (CDR) is widely recognised as essential for pathways consistent with the Paris Climate Agreement. Yet the cost-dependent potential of CDR options, given resource competition, remains uncertain. Here we present CDR-supply curves assessing a range of CDR options across carbon price levels using five Integrated Assessment Models (IAMs) for 2035, 2050 and 2100. At 400 (200) $ tCO₂⁻¹, global CDR potential reaches 2.6-9.7 (2.1-6.0) GtCO₂ yr⁻¹ in 2050 and 10.3-20.9 (5.9-12.4) GtCO₂ yr⁻¹ in 2100, with higher prices enabling more diverse portfolios. Cross-model comparison shows that DACCS has the largest variability, while BECCS is consistently deployed; overall, options with geological storage dominate. CDR deployment drives resource demand, but with diversified portfolios these impacts are small compared to total energy and land use. These results indicate sufficient global technical CDR potential to meet long-term strategy (LTS) targets, though achieving this requires substantial policy and financial support.
