中国広西地域の道路移動発生源を対象に、経済・人口要因を統合した非線形予測モデルを用いて、将来の活動量とCO2・大気汚染物質の排出を動的に評価。環境税と炭素取引価格を組み合わせ、排出削減の経済的便益を定量化した。最も楽観的なシナリオではCO2排出を47.86%削減可能だが、BAUシナリオではNOX排出が60.49%増加する。弾力性係数が1に収束し、厳格な緩和策が相乗効果を高めることを示した。
English
This study develops nonlinear prediction models integrating economic and demographic drivers to dynamically assess CO2 and air pollutant emissions from on-road mobile sources in Guangxi, China. Combining environmental tax rates and carbon trading prices, it quantifies the economic benefits of emission reductions. Under the most optimistic scenario, 47.86% of CO2 emissions could be mitigated, while NOX emissions may increase by 60.49% in the BAU scenario. Elasticity coefficients converging to 1 indicate that stricter mitigation enhances co-benefits, offering insights for co-managing CO2 and air pollutants along the Belt and Road regions.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では交通部門の脱炭素化が進むが、大気汚染との同時削減（コベネフィット）の定量評価は限定的。本研究成果は、日本の自治体や企業が運輸部門の排出削減策を評価する際の方法論として参考になる。また、中国の政策動向を理解する上でも有用。
In the global GX context
This study provides a quantitative framework for assessing co-benefits of CO2 and air pollutant reductions in the transport sector, relevant to global efforts under TCFD/ISSB disclosure and transition finance. The methodology combining environmental taxes and carbon pricing offers insights for policymakers and companies in emerging economies, particularly along the Belt and Road Initiative, to design integrated mitigation strategies.

📄 Abstract（原文）
The transport sector has emerged as a significant source of greenhouse gases and airborne pollutants. However, few studies have carried out a comprehensive assessment of the synergistic benefits between air pollutant and carbon emission reductions that account for the unique regional characteristics of individual provinces. In this study, we establish nonlinear prediction models for future activity levels of on-road mobile sources by integrating economic and demographic drivers. We then dynamically quantify the co-benefits of simultaneous air pollutant and CO2 abatement under diverse mitigation scenarios. Environmental tax rates and carbon trading prices are combined with conventional elasticity coefficients and coordinate-based methodologies to convert emission cuts into economic advantages. The results show that under the most optimistic scenario, 47.86% of the CO2 emissions could be mitigated, while emissions of NOX may increase by 60.49% in the absence of mitigation strategies (BAU scenario). Marginal CO2 emissions under the ELC scenario indicates a peak around 2027. Elasticity coefficients for all pollutants gradually converge toward 1, indicating that more stringent mitigation efforts enhance co-benefits. Findings in this study could provide essential insights for the co-management of CO2 and air pollutants from road mobile sources in Guangxi and other key regions along the Belt and Road Initiative.
