パリ協定後の2016〜2025年におけるCDR研究を、Web of Scienceの4281件の文献を用いて計量書誌学的に分析。2019年以降に研究が急増し、工学的手法と自然を基盤とした手法の2つの流れが存在するが、両者の直接的な連携が弱いことを示した。テーマ進化は政策枠組みからBECCS・中立性、そしてバイオ炭・自然を基盤とした除去へと移行している。
English
This bibliometric study maps carbon dioxide removal (CDR) research from 2016 to 2025 using 4,281 Web of Science records. Output surged after 2019, aligning with net-zero targets. Four thematic clusters emerged, but the direct link between engineered and nature-based removal is weak, indicating an integration deficit at the engineered-ecological interface. Thematic evolution shifted from policy framing to BECCS and neutrality, then to biochar and nature-based removal.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では、ネットゼロ目標達成に向けてCDRの位置づけが重要であり、特にDACCSやBECCSなどの技術開発が進む。本分析は、日本におけるCDR研究の現状と国際的な連携の不足を示唆し、今後の研究戦略や国際共同研究の促進に示唆を与える。
In the global GX context
Globally, CDR is critical for net-zero pathways, yet the field is fragmented between engineered and nature-based approaches. This study highlights the need for cross-disciplinary integration, which is relevant for international research policy and for informing IPCC and national climate strategies.

📄 Abstract（原文）
The Paris Agreement (2015) shifted global climate policy toward net-zero emissions, requiring both deep decarbonization and large-scale carbon dioxide removal (CDR) to neutralise residual emissions from hard-to-abate sectors. Research has developed along two largely separate streams: engineered removal (BECCS, DACCS, biochar, enhanced weathering) and nature-based solutions (afforestation, soil carbon sequestration). This study maps CDR research, as framed within climate-policy discourse, between 2016 and 2025, using 4281 records from the Web of Science Core Collection analysed with VOSviewer and Bibliometrix and screened following PRISMA 2020 guidelines. Output accelerated sharply after 2019, coinciding with the consolidation of net-zero targets. Network analysis identifies four thematic clusters (modularity Q = 0.19, exceeding a degree-preserving null model by 65 standard deviations): engineered removal, nature-based removal, soil-carbon science, and a CDR-policy core. The field is thematically structured but not globally siloed: most keyword co-occurrence links (54%) are cross-cluster and every cluster’s external-internal index is positive. Fragmentation is instead localised—the direct link between the engineered and nature-based clusters is the weakest coupling (10.3% of link weight), the two pillars connecting mainly indirectly through the soil-carbon and policy clusters. Thematic evolution runs from policy framing (2016–2019) to BECCS and neutrality themes (2020–2022) and to biochar and nature-based removal (2023–2025). Publication output is dominated by China and the United States, while the United Kingdom acts as the principal international broker. These findings indicate that the main integration deficit lies at the engineered-ecological interface, where targeted cross-disciplinary work would most directly strengthen the evidence base for net-zero pathways.
