この研究は、運輸部門からのCO2と大気汚染物質の同時削減のコベネフィットを評価した。ランダムフォレストモデルでPM2.5濃度を予測し、GEMMで健康便益を算定。最良シナリオではCO2排出量が2032年にピークアウトし、2050年までに51.71%削減、17,297人の早死を回避可能。環境税や炭素取引価格を統合した経済評価も実施。
English
This study evaluates co-benefits of reducing CO2 and air pollutants from transport. A random forest model predicts PM2.5 concentrations and health benefits are estimated using GEMM. In the best scenario, CO2 emissions peak in 2032 with a 51.71% reduction, and 17,297 premature deaths prevented by 2050. Economic benefits from CO2 reduction reach 10.81 billion CNY by 2050.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
中国の運輸部門に焦点を当てており、日本の自動車産業や交通政策にも示唆を与える。特に、環境税と炭素取引の統合的活用は日本のGX政策（GXリーグ、炭素価格）の設計に参考となる。また、PM2.5削減による健康便益の定量化は、日本の大気環境政策推進の根拠になり得る。
In the global GX context
This paper provides empirical evidence on co-benefits of emission reductions, which is relevant for global climate and air quality policy integration. The use of random forest to model health impacts and the incorporation of carbon pricing can inform similar analyses in other countries. The findings support the concept of synergistic management as promoted by the UNEP and WHO.

📄 Abstract（原文）
The transport sector contributes significantly to greenhouse gases and airborne pollutants. This study focuses on the co-benefits related to decreases in air pollutants and CO2 emissions under various mitigation scenarios. The associated mitigations in PM2.5 concentrations are predicted by establishing a random forest (RF) model and the health benefits are evaluated with the global exposure mortality model (GEMM). Environmental tax values and carbon trading prices are integrated alongside traditional elasticity coefficients and coordinate-based approaches to transform reductions into economic advantages. The results indicate that in the most favorable scenario (ELC), CO2 emissions are expected to peak in 2032 with a reduction of 51.71%; this is supported by the marginal CO2 emission curve, which intersects the zero axis around that same year, while the air pollution equivalents (APeq) are projected to decline by 25.65% in 2050. The efficiency of synergistic reductions between air pollutants and CO2 ranks as SO2 > NOX > CO > HC > PM2.5 > PM10, and the elasticity coefficients for all pollutants are gradually aligning toward 1, suggesting that stricter mitigation efforts will enhance co-benefits. Furthermore, the economic benefits attributable to CO2 reduction are anticipated to be 10.81 billion CNY by 2050, and 17,297 premature deaths associated with PM2.5 exposure could be prevented. The findings in this study could provide essential insights for the co-management of CO2 and air pollutants from road mobile sources.
