農業・林業残渣（AFR）を活用した統合型AFR-to-Energyシステム（IAES）を、全球変化分析モデルとライフサイクル評価を組み合わせて評価した研究。2060年までのSSP-RCPシナリオ下で、SDGsへの寄与が地域の残渣賦存量・技術構成・社会経済条件により大きく異なることを示す。カナダや東欧は高い持続可能性便益を示す一方、多くの低中所得地域や中国では限定的な見通しにとどまる。
English
Integrating the Global Change Analysis Model with life cycle assessment in an optimized AFR-to-Energy System framework, this study evaluates SDG-related contributions of global residue-based bioenergy deployment to 2060 across SSP-RCP scenarios. Benefits vary widely by region due to differences in residue availability, technology configuration, and socioeconomic conditions. Canada and Eastern Europe show strong gains, while many lower-income regions and China show limited prospects.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本はバイオマス発電のFIT依存と燃料輸入依存が課題であり、残渣調達・地域別便益の評価枠組みは国内のバイオエネルギー政策や企業の再エネ調達戦略に示唆を与える。SSBJ開示における再エネ・脱炭素投資の根拠づけにも資する。
In the global GX context
For global disclosure scholarship, this work links bioenergy deployment pathways to SDG outcomes under SSP-RCP scenarios, offering scenario-based evidence relevant to transition finance and corporate renewable procurement narratives under ISSB/CSRD. It highlights regional heterogeneity that complicates uniform sustainability claims.
👥 読者別の含意

📄 Abstract（原文）
Amid rising global demand for sustainable energy, agricultural and forestry residues (AFRs) emerge as a key yet underutilized resource in energy transition. Mechanisms of how optimizing multipath AFR utilization advances sustainability contributions in varied socioeconomic contexts remain underexplored. Integrating the Global Change Analysis Model and life cycle assessment within an optimized Integrated AFR-to-Energy System (IAES) framework, we evaluate the selected Sustainable Development Goals (SDGs)-related contributions of global IAES deployment across combined Shared Socioeconomic Pathways-Representative Concentration Pathways scenarios until 2060. Our results reveal that regional disparities in the contributions to SDGs are driven by variations in AFR availability, technology configurations, and socioeconomic conditions. Most lower-middle-to-low income regions struggle to achieve meaningful sustainability benefits. Canada, where energy output from IAES deployment could meet nearly 20% of its energy demand by 2060, leads the sustainability gains excelling in SDG7 and SDG13, followed by Eastern Europe that strides in SDG1, while China shows comparatively limited prospects. This study offers a comparative, scenario-based basis for informing bioenergy deployment strategies across regional contexts to advance energy transition and the SDGs. This study shows that deploying agricultural and forestry residue-based bioenergy globally could advance multiple Sustainable Development Goals, with benefits varying substantially by region and socioeconomic scenario.
