本論文は、IPCC定義に沿った「炭素隔離」、すなわち植物による大気中CO2の実際の除去と土壌への保持に基づく算定手法を提案する。実 biomass 量・質、気温、降水量、粘土含量を入力とし、実圃場で検証した結果、既存の全球隔離予測モデルと概ね整合した。併せて既存モデルに欠けていた炭素隔離評価スケールを開発し、スロバキアの農業デジタル助言プラットフォームAgroAssistentへの実装を予定する。
English
The paper proposes a carbon sequestration calculation method grounded in the IPCC definition—actual CO2 removal by plants and its retention in soil—rather than conflating sequestration with carbon stocks or balance. Inputs include real biomass quantity/quality plus temperature, precipitation, and clay content; field-plot tests show results broadly consistent with global sequestration models. It also introduces a sequestration assessment scale absent from existing models, to be embedded in Slovakia's AgroAssistent advisory platform.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
土壌炭素はScope 3・農業由来排出の算定やSBTiのFLAG目標で重要性が増しており、炭素隔離と炭素ストックの混同を戒める本稿の指摘は、日本企業の農業・食品サプライチェーン算定の精度向上に示唆を与える。ただし国内制度への直接接続は限定的。
In the global GX context
Soil carbon is increasingly material to Scope 3 agriculture/food accounting and SBTi FLAG targets; the paper's warning against conflating sequestration with carbon stocks speaks to the rigor gap in corporate land-sector claims. It offers methodological discipline for GHG Protocol land-sector and removals accounting debates, though it is not tied to TCFD/ISSB disclosure requirements directly.

📄 Abstract（原文）
The concept of carbon sequestration is widely misunderstood, leading to misleading conclusions that are reflected in unrealistic climate change mitigation strategies. Most studies presented as carbon sequestration do not understand the term carbon sequestration in accordance with the IPCC definition. Most often, carbon sequestration is equated with carbon stocks or carbon balance. As a result, carbon sequestration models continue to be developed worldwide that have little in common with sequestration. Our methodology for calculating carbon sequestration is based on a definition grounded in the actual removal of CO2 from the atmosphere by plants and its retention in the soil. The input data include real values for the quantity and quality of incoming biomass in relation to the plant, as well as real data on the main factors determining the geographical distribution of carbon on Earth in relation to the soil, such as temperature, precipitation, and clay content. Testing of the methodology on real field plots in practice has shown that the results are compatible with global sequestration prediction models or closely approximate them. Simultaneously, a scale for assessing carbon sequestration was developed, which is still absent in existing models. The methodology will be part of the digital advisory platform AgroAssistent, which will serve common farming practice within Slovakia.
