本研究は、米国の異なる脱炭素経路において大気汚染削減がエネルギー負担の高い地域にどのように影響するかを調査。急速な炭素削減（1.5°C経路、2035年までの再生可能エネルギー100%）は、脆弱なコミュニティでのPM2.5曝露を早期に均一化する一方、緩やかなシナリオでは格差が残る。エネルギー移行政策における環境正義の重要性を示す。
English
This study investigates how air pollution reductions affect energy-burdened populations across different US decarbonization pathways. Rapid carbon reduction scenarios (1.5°C pathway, 100% renewable by 2035) achieve near parity in PM2.5 exposure before 2030, while less aggressive scenarios show persistent disparities. Results inform equitable energy transition policies.

📄 Abstract（原文）
Abstract This study investigates how air pollution reductions intersect with energy-burdened populations across different US decarbonization pathways. The urgent need for decarbonization arises from the imperative to mitigate climate change and reduce national air pollution levels. However, without deliberate planning for equitable outcomes, existing disparities in the US energy system may be exacerbated. This research addresses this concern by examining PM 2.5 air pollution concentration and associated mortality rates, while also exploring the correlation with household energy costs at the census tract level. We quantify air pollution impacts using PM 2.5 concentrations and report premature mortality as the resulting health outcome, calculated by applying established concentration–response relationships to the modeled changes in PM 2.5 concentrations. We find that rapid carbon reduction models, such as the 1.5 °C pathway and 100% renewable energy by 2035, demonstrate significant air pollution reductions in highly vulnerable communities, achieving near parity in PM 2.5 exposure across energy burden groups before 2030. Conversely, less aggressive scenarios, such as the “100% Renewable Energy by 2050” scenario, show marginal disparities in PM 2.5 levels between high- and low-energy-burdened groups. Additionally, a sensitivity analysis addresses modeling assumptions and the implications of dynamic energy costs across socioeconomic groups. By highlighting the role of decarbonization pathways in minimizing air pollution disparities among socioeconomic groups, this research informs future energy transition policies and makes evident the importance of achieving environmental justice and equitable outcomes for vulnerable populations.
