本研究は、EUの農業土壌におけるバイオ炭施用の経済的便益を2020年から2050年まで動的最適化モデルで分析。バイオ炭は今後10年以内に経済的に viable となり、2050年までに最適炭素ストックはhaあたり0.6〜6.8トンに達する。炭素価格や生産コストが影響し、総正味現在価値は2120億ユーロ（うちバイオ炭360億ユーロ）と推定。

English

This study analyzes the economic benefits of biochar application in EU agricultural soils from 2020 to 2050 using a dynamic optimization model. Biochar becomes economically viable within a decade, with optimal carbon stocks reaching 0.6-6.8 t/ha by 2050. Net present value of sequestration is about €212 billion, including €36 billion from biochar, influenced by carbon pricing and production costs.

📄 Abstract（原文）

Biochar application on agricultural land is promoted for its high permanence as a carbon sink. This study examines the spatiotemporal dynamics and economic net benefits of biochar sequestration in EU agricultural soils from 2020 to 2050. A discrete time dynamic economic optimization model, spatially disaggregated across 26 EU member states, evaluates trade-offs between using agricultural residues for biochar, bioenergy, direct soil incorporation, and cover crops. Results show that biochar will become economically viable within the next decade, with optimal carbon stocks reaching 0.6–6.8 tonnes per hectare by 2050. Countries with abundant biomass benefit most due to economies of scale and lower transport costs. By 2050, optimal carbon sequestration yields a net present value of about 212 billion euro, including 36 billion from biochar. Sensitivity analysis underscores the influence of carbon pricing, production costs, and regional biomass supply. Biochar thus offers a cost-effective, regionally variable mitigation option for the EU.
