本研究はパキスタン運輸部門初の技術分解・高解像度・多汚染物質排出インベントリを作成し、GAINSモデルを用いてBAU、電動化(EVT)、排出基準強化(Euro-VI)、統合NDC+(NDC+)の4シナリオを評価。2024年の排出量はPM2.5約22kt、NOx 300kt超、CO2約39Mtと推定。2050年にはNDC+シナリオが最大の削減効果を示し、電動化と排出規制の統合が大気質改善と気候対策の相乗効果をもたらすことを実証した。
English
This study develops the first technology-resolved, high-resolution, multi-pollutant emission inventory for Pakistan's transport sector using the GAINS model. It projects emissions under BAU, EV transition (EVT), Euro-VI, and integrated NDC+ scenarios through 2050. The NDC+ scenario achieves the largest reductions, demonstrating that coordinated electrification and emission control strategies can simultaneously reduce air pollution and greenhouse gas emissions, providing evidence for Pakistan's NDC implementation and sustainable mobility planning.

日本のGX文脈において
パキスタン運輸部門の実証分析だが、日本にとってはアジア途上国での統合的対策の知見として参考になる。特に、電動化と排出基準の組み合わせがもたらす相乗効果の定量評価は、日本の国際協力や技術輸出の文脈で示唆に富む。
In the global GX context
This paper provides robust empirical evidence from a developing country context, demonstrating that integrated transport decarbonization strategies combining electrification and stringent standards yield significant co-benefits for climate and air quality. The findings are highly relevant for global climate policy, especially for countries updating their NDCs and pursuing sustainable mobility transitions, and offer transferable lessons for rapidly developing economies.

📄 Abstract（原文）
The transport sector is a major contributor to urban air pollution and greenhouse gas emissions in Pakistan, posing significant challenges to sustainable development and climate commitments. This study develops the first technology-resolved, high-resolution, multi-pollutant emission inventory and scenario analysis for Pakistan’s transport sector, addressing key gaps in previous studies that lacked integrated multi-pollutant assessments, comprehensive coverage of non-road sources, and long-term scenario comparisons. The analysis integrates road and non-road transport sources within the Greenhouse Gas–Air Pollution Interactions and Synergies (GAINS) modeling framework. Emissions are projected for 2024–2050 under a business-as-usual (BAU) scenario and three mitigation pathways: an Electric Vehicle Transition (EVT) emphasizing transport electrification, a Euro-VI scenario focusing on stringent fuel and vehicle emission standards, and an integrated nationally determined contribution strategy (NDC+) scenario combining electrification, regulatory improvements, and structural transport reforms. In 2024, transport-related emissions are estimated at approximately 22 kt of fine particulate matter (PM2.5), over 300 kt of nitrogen oxides (NOx), and nearly 39 Mt of carbon dioxide (CO2), alongside substantial emissions of other gaseous pollutants and short-lived climate forcers. By 2050, the NDC+ scenario achieves the largest reductions relative to business-as-usual, demonstrating that coordinated electrification and emission control strategies can simultaneously reduce air pollution and greenhouse gas emissions. The results demonstrate strong synergies between climate mitigation and air quality improvement, showing that integrated strategies combining electrification with stringent emission standards can simultaneously reduce greenhouse gas emissions and major air pollutants while advancing cleaner and more sustainable mobility. This analysis provides a consistent and policy-relevant evidence base derived from best-available data and modeling tools to support Pakistan’s NDC implementation, sustainable mobility planning, and integrated air quality and climate strategies, with lessons transferable to other rapidly developing economies.
