本研究は2つの経済モデルを用いて、ブラジルのサトウキビエタノール生産を2024/2025年収穫比で37%拡大した場合の影響を分析。その結果、食料安全保障にわずかに正の影響を与え、気候緩和シナリオ下では2030年までに食料消費が6%増加、一人当たりGDPが2～3.5%上昇すると示した。高いエネルギー収量と低炭素フットプリントが要因。
English
Using two independent economy-wide models, this study evaluates a 37% expansion of Brazilian sugarcane ethanol production. It finds slightly positive impacts on food security, and under climate mitigation scenarios, a 6% increase in food consumption and 2–3.5% rise in GDP per capita by 2030, due to the industry's high energy yield, low carbon footprint, and income effects.

日本のGX文脈において
日本はバイオ燃料の持続可能性基準を強化しており、本研究成果は食料安全保障とGHG削減の両立可能性を示す点で参考となる。ただしブラジル固有の条件に依存するため直接適用には注意が必要。
In the global GX context
This paper provides robust empirical evidence that bioenergy expansion can simultaneously support climate goals and food security, informing global debates on sustainable biofuel policies and their integration into NDCs.

📄 Abstract（原文）
ABSTRACT The growing global demand for biofuels has raised concern about compromising food security. This study uses two independent economy‐wide models to evaluate the impact of expanding the Brazilian sugarcane bioenergy system on economic growth, social outcomes and food security. Our analysis finds that increasing Brazilian sugarcane ethanol production by 37% over the 2024/2025 harvest has slightly positive impacts on food security, with marginal but variable effects on prices and household consumption across regions, depending on the model assumptions and analyzed scenario. Under future climate mitigation scenarios, expanding the sugarcane bioenergy system would result in a 6% increase in food consumption and between 2% and 3.5% rise in Brazil's gross domestic product per capita by 2030. These outcomes stem from the properties of the sugarcane ethanol industry, including its high energy yield, low carbon footprint, contribution to labor and income generation, and role in agricultural intensification. Our results demonstrate the importance of considering comprehensive economic linkages when evaluating bioenergy impacts, including income‐side effects, thereby moving beyond isolated price‐based analyses.
