本論文は、3つの米国エネルギーシステムモデルを用いて、ネットゼロ排出への移行が大気質と健康に与える影響を分析。結果、移行によりPM2.5濃度と関連死亡率が全国的に減少する一方、その恩恵はモデルや地域によって大きく異なることを示す。特に二酸化炭素除去技術の活用が排出の地域間再配分を引き起こし、局所的な汚染増加につながる可能性がある。
English
This multi-model analysis of U.S. net-zero transition finds robust nationwide reductions in PM2.5 and associated mortality, but benefits vary substantially across models and regions due to differences in sectoral mitigation allocation and use of carbon dioxide removal, which can relocate residual emissions and sometimes increase local pollution.

👥 読者別の含意
🔬研究者:Multi-model comparison reveals robust findings and uncertainties in health cobenefits of net-zero transitions, informing further research on sectoral strategies and CDR deployment.
🏢実務担当者:Corporate decarbonization planners can use these insights to anticipate how net-zero strategies may affect local air quality and stakeholder relations.
🏛政策担当者:Policymakers should consider that CDR and sectoral mitigation choices influence the distribution of air quality benefits, requiring careful policy design to avoid local pollution hotspots.
📄 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.
