泥炭地再湿潤はGHG排出削減とCO2除去(CDR)の両方に寄与する。本論文は持続的昇温ポテンシャル(GWP*)を用い、ドイツの排出係数に基づく最良・最悪シナリオを評価。パルディカルチャーによる長期的炭素貯蔵も考慮し、他のCDR技術との比較から生態系サービスとの相乗効果を示した。気候政策や炭素会計への統合に科学的根拠を提供。
English
This paper evaluates peatland rewetting for emission reduction and carbon dioxide removal (CDR) using radiative forcing modeling and the GWP* metric with German emission factors. It analyzes best- and worst-case scenarios, including CH4 pulses and CO2 sequestration, and quantifies additional CDR from paludiculture products. Compared to other CDR techniques, peatland rewetting offers synergies in ecosystem services and biodiversity. The findings support better integration into climate policies and carbon accounting frameworks.

日本のGX文脈において
日本では泥炭地が限られるが、炭素除去の計算法や政策統合の枠組みは、Jクレジットや森林吸収源評価に示唆を与える。GWP*の適用事例としても参考になる。
In the global GX context
This paper advances the global debate on integrating nature-based solutions into carbon accounting by clarifying the distinct roles of emission reductions and CDR. It provides a rigorous method for evaluating peatland rewetting under the GWP* metric, which can inform IPCC guidelines and national inventory improvements. The contrast with other CDR options highlights the unique co-benefits of peatland restoration for climate and biodiversity.

📄 Abstract（原文）
Peatland rewetting can reduce greenhouse gas (GHG) emissions (stopping the leak) and establish Carbon Dioxide Removals (CDR, rebuild the CO2 sink). Emission reductions and CDR are two distinct climate change mitigation strategies that require tailored accounting methodologies and regulatory designs to ensure environmental integrity.Here, we evaluate the potential, constraints and uncertainties of rewetting agriculturally drained peatlands as a strategy for emission reduction and CDR. Our analysis utilizes radiative forcing modeling and the sustained global warming potential (GWP*) metric, applied to emission factors from Germany’s national inventory reporting. Further, to account for the large variety of rewetting outcomes, we incorporate two emission trajectories in our evaluation: first, a worst-case scenario characterized by high initial CH4 pulses and delayed CO2 sequestration due to year-round flooding and, second, a best-case scenario, featuring low CH4 emissions and high initial CO2 sequestration associated with precise water table management and the rapid establishement of wetland vegetation. Furthermore, we quantify additional CDR gains derived from long-term carbon storage in products from paludiculture biomass and, finally, contrast peatland rewetting with alternative CDR techniques, highlighting its synergies in ecosystem services and biodiversity conservation.Our findings contribute to the scientific basis for better integrating peatland rewetting into climate policies and accounting schemes, ensuring that regulatory frameworks most accurately reflect the climate change mitigation potential of rewetting agriculturally drained peatlands.
