ブラジル法定アマゾンの760自治体を1990〜2023年にわたり分析し、純排出量ではなく総農業排出量に着目。PVARモデルで排出量・森林減少・森林被覆・人口の動的関係を検証した。総排出量は強い持続性と森林減少との双方向関係を示し、自治体間の緩和能力の不均等を浮き彫りにした。低炭素農業と森林保全を統合した地域別政策の必要性を示唆する。
English
Analyzing 760 municipalities in the Brazilian Legal Amazon (1990-2023), this study focuses on gross rather than net agricultural emissions using a PVAR model. Results show strong persistence in emissions, a robust bidirectional relationship with deforestation, and limited short-run effects of forest cover and population. Findings reveal unequal mitigation capacities across territories, underscoring the need for differentiated low-carbon agriculture and conservation policies.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本のGX文脈とは直接接続しないが、Scope 3上流の農業・土地利用排出や地域別緩和経路の設計、気候正義の観点は、サプライチェーン排出管理や自治体レベルの脱炭素計画を考える日本企業・自治体に示唆を与える。
In the global GX context
While focused on Brazil, this work contributes to global disclosure scholarship by demonstrating how gross emission accounting reveals structural drivers and spatial inequalities that net accounting obscures—relevant to Scope 3 land-use accounting and territory-differentiated transition planning under ISSB/CSRD frameworks.

📄 Abstract（原文）
ABSTRACT Climate mitigation policies in the Brazilian Legal Amazon have largely focused on aggregate or net emissions, providing limited evidence on how gross agricultural emissions reveal the intensity of productive emission sources independently of carbon removals. This gap constrains the development of territorially differentiated policies capable of advancing climate action, environmental conservation and social equity. This study analyses the dynamic relationships among gross agricultural emissions, deforestation, forest cover and population across 760 municipalities in the Brazilian Legal Amazon between 1990 and 2023, discussing implications for climate mitigation and climate justice. By focusing on gross rather than net emissions, the analysis isolates the productive component of greenhouse gas emissions and identifies municipalities where agricultural activities exert greater climate pressure regardless of carbon sequestration capacity. A Panel Vector Autoregression (PVAR) model is employed to examine dynamic interactions among the variables. Results indicate strong persistence in gross agricultural emissions, a robust bidirectional relationship between emissions and deforestation, and limited short‐run effects of forest cover and population. These findings show that agricultural production systems and land‐use change reinforce heterogeneous emission trajectories across municipalities, reflecting unequal mitigation capacities and territorial conditions. Although climate justice is not directly measured, the study provides empirical evidence of territorial asymmetries shaping mitigation pathways and highlights the need for differentiated policies integrating low‐carbon agriculture, forest conservation and governance. The study demonstrates that gross agricultural emissions complement net emissions by revealing structural drivers and spatial inequalities influencing climate mitigation in the Brazilian Legal Amazon.
