本研究は、EUの農業用有機土壌の回復による温室効果ガス削減の経済的可能性を評価。3つの回復措置（完全再湿潤、リハビリテーション、完全再湿潤＋パルディカルチャー）を分析し、炭素価格100ユーロ時に38.2～44.4 MtCO2e/年の削減が可能と示す。パルディカルチャー需要により追加的な気候政策なしでも200万haの回復が可能で、EU自然回復規則目標達成により現状排出量の23～29%削減に相当する。政策統合の重要性を強調。
English
This study assesses the cost-effectiveness of restoring drained organic soils in EU agriculture. Under a 100 EUR/tCO2e carbon price, 38.2-44.4 MtCO2e/yr could be mitigated by 2050. Paludiculture demand could enable 2 Mha restoration without additional climate incentives, delivering 17 MtCO2e/yr. Meeting EU Nature Restoration Regulation targets alone could mitigate 20-26 MtCO2e/yr, equivalent to 23-29% of current emissions. The findings highlight synergies between climate, bioeconomy, and nature restoration policies.

日本のGX文脈において
本論文はEUの政策文脈に特化しているが、日本の農業部門における有機土壌管理（例：北海道の泥炭地）やGHG削減策の費用対効果評価に示唆を与える。特に、炭素価格や自然再生目標との連携による複合便益の統合的設計は、日本の農林水産省や環境省の政策立案にも参考となる。
In the global GX context
This paper provides a rigorous economic assessment of a key land-use mitigation option in the EU, relevant for global climate policy design. It demonstrates how integrating climate, biodiversity, and bioeconomy goals can achieve cost-effective GHG reductions, offering lessons for other regions (e.g., under CSRD, TNFD) where organic soil restoration is a neglected opportunity.

📄 Abstract（原文）
Abstract Drained organic soils in agricultural use in the European Union (EU) contribute approximately 80% of Cropland and Grassland greenhouse gas (GHG) emissions released to the atmosphere, which makes their restoration highly relevant for achieving climate change mitigation targets in the EU. However, the cost-effectiveness of different restoration measures and their synergies with economic incentives remain poorly understood. Here, we provide an EU-wide assessment of the economic potential of restoring drained organic soils used for agriculture through 2050 using the economic land-use model GLOBIOM-EU. We investigate the climate benefits of three restoration measures—full rewetting, rehabilitation, and full rewetting with paludiculture—and evaluate their cost-effectiveness by developing marginal abatement cost curves (MACCs). Our results indicate that under a GHG price of 100 EUR tCO 2 e −1 , 38.2–44.4 MtCO 2 e yr −1 could be mitigated in 2050. Demand for paludiculture products would substantially improve the attractivity of full rewetting, enabling up to 2 Mha of drained organic soils to be restored even without additional climate policy incentives, delivering 17 MtCO 2 e yr −1 mitigation in 2050. In addition, meeting the 2050 targets of the EU Nature Restoration Regulation (NRR) alone could mitigate emissions by 20–26 MtCO 2 e yr −1 , equivalent to 23%–29% of current emissions from drained agricultural organic soils in the EU. These findings demonstrate that restoring drained organic soils represents a substantial mitigation opportunity for the EU agricultural sector, with synergies for bioeconomy development and nature restoration. An integrated approach to policy design is needed to ensure efficiency in delivering multiple co-benefits.
