本論文は、気候中立達成のためにはすべての化石炭素の使用を段階的に廃止する必要があるが、化学、素材、航空、海上輸送などのセクターは依然として炭素を必要とすることを指摘する。CO2を燃料や化学品、素材に変換する炭素回収・有効利用（CCU）技術が、これらのセクターでの化石炭素代替に貢献できる。最新のIPCC報告書によれば、コストやモデルの不確実性はあるものの、CCUは気候変動緩和に重要な役割を果たす可能性がある。
English
This paper argues that phasing out virgin fossil carbon is essential for climate neutrality, but sectors like chemicals, materials, aviation, and maritime will still need carbon. Carbon Capture and Utilisation (CCU) can replace fossil carbon by converting captured CO2 into fuels, chemicals, and materials. The paper emphasizes CCU's mitigation potential as highlighted in the latest IPCC WG3 report, despite uncertainties in renewable electricity costs and model granularity.

日本のGX文脈において
本論文は、日本が2050年カーボンニュートラル達成に向けて、特に鉄鋼や化学などの排出削減が困難なセクターでCCUS技術の重要性を認識していることと関連する。循環型炭素経済の概念は、日本の資源効率化目標とも合致し、GXリーグの取り組みに示唆を与える。
In the global GX context
Globally, this paper contributes to the discussion on CCU's role in climate mitigation, particularly for hard-to-abate sectors. It aligns with global frameworks like the IPCC reports and the growing interest in circular economy approaches to decarbonization. The paper emphasizes the need for policy support and cost reductions for CCU technologies.

📄 Abstract（原文）
For several decades, exponential growth in the use of fossil carbon has created drastic climate disturbances. To mitigate climate change, all uses of virgin fossil carbon must, urgently, be phased out. Many transport sources and industrial processes can easily be electrified and should be where possible. But some sectors like chemical, materials (e.g. lime and steel), aviation and maritime transport will continue to use carbon and the virgin fossil used today will need to be substituted to meet climate neutrality targets. Using CO2 to replace fossil carbon in sectors that will still need hydrocarbons is a key solution to “defossilise” our economy. The concept of Carbon Capture and Utilisation (CCU) is a broad term that covers processes that capture CO2 from flue and process gases or directly from the air and convert it into a variety of products such as fuels, chemicals, and materials. No precise global estimate of the potential mitigation role of CCU technologies exists to date, because of uncertainties in renewable electricity cost scenarios and the low granularity of models that simulate different CCU options. However, CCU technologies have the potential to play a significant role in the mitigation of climate change as described in the latest report from Working Group 3 of the Intergovernmental Panel on Climate Change (IPCC).
