本論文は、米国の3つのエネルギー・モデルを用いて、ネットゼロ移行が大気質と健康に与える影響を分析。2050年までの移行によりPM2.5濃度と関連死亡率が全国的に減少するが、便益の大きさはモデルや地域によって大きく異なることを示した。その差異は、二酸化炭素除去技術の利用など、部門間の緩和努力の配分に起因する。
English
This multi-model analysis for the U.S. shows that a net-zero transition robustly reduces PM2.5 concentrations and associated mortality nationwide by 2050, but health co-benefits vary substantially across models and regions. Differences arise from how mitigation is allocated across sectors, especially the use of carbon dioxide removal technologies which can relocate residual emissions and locally increase pollution.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でもネットゼロ目標達成に向けてエネルギー技術の選択が重要な政策課題となっており、本分析の方法論は日本のエネルギー・政策モデルに応用可能。特に、CO2除去技術の地域的影響評価は、日本のCCUS戦略や地域間格差の検討に示唆を与える。
In the global GX context
This study provides critical insights for global climate policy by quantifying the air quality and health co-benefits of net-zero transitions. It underscores that technology choices—especially reliance on carbon dioxide removal—can shift pollution burdens across regions, a key consideration for equitable transition planning under the Paris Agreement.

📄 Abstract（原文）
Transitioning to a net-zero emissions economy can provide air quality and health benefits. Yet it is still unclear how different low-carbon energy strategies influence the overall benefits and their distribution. Based on a multi-model analysis using three leading energy models for the U.S. (GCAM-USA, US-REGEN, and REPEAT), we demonstrate that a net-zero transition from now to 2050 yields robust nationwide reductions in ambient concentrations of fine particulate matter (PM2.5) and associated mortality. However, the health co-benefits achieved in the net-zero scenarios relative to business-as-usual baselines vary substantially across models and regions. These differences largely result from how mitigation efforts are allocated across sectors, especially the use of carbon dioxide removal technologies, which can relocate residual emissions across regions and, in some cases, increase local pollution levels. As pollution from non-energy activities such as wildfires continues to grow, minimizing energy-related emissions is critical to counteract potential increases in other sectors.
