本研究は、LEAP-Beijing、限界削減費用（MAC）分析、WRF-Chem大気質モデルを結合した統合モデリングフレームワークを開発し、2030年から2050年の北京のエネルギー・排出経路をシミュレーションした。37の緩和技術を評価し、最適シナリオではCO2を59.29%、NOxを81.34%削減できることを示した。主要対策は電気トラック、建物外皮改修、太陽光発電であり、PM2.5とNO2濃度の低下が期待されるが、冬季オゾンは増加する。VOC対策の必要性も指摘している。

This study develops an integrated modeling framework combining LEAP-Beijing, Marginal Abatement Cost analysis, and WRF-Chem to simulate Beijing's energy-emission pathways from 2030 to 2050. It evaluates 37 mitigation technologies and identifies an optimal scenario achieving 59.29% CO2 and 81.34% NOx reductions. Key measures include battery-electric trucks, building retrofits, and photovoltaic expansion, leading to PM2.5 and NO2 reductions of 6% and 24%, though winter ozone increases by 10%. The findings emphasize the need for VOC control measures alongside carbon reduction.

📄 Abstract（原文）
Abstract As China’s capital, Beijing has significantly improved its air quality, yet the synergistic reduction of atmospheric pollutants and greenhouse gases remains a critical challenge. This study pioneers an integrated modeling framework that couples the Long-range Energy Alternatives Planning system (LEAP-Beijing), Marginal Abatement Cost (MAC) analysis, and the WRF-Chem air quality model. This approach simulates Beijing’s energy-emission pathways from 2030 to 2050, techno-economically evaluates 37 mitigation technologies, and quantifies their resultant air quality impacts. Our findings identify an enhanced energy mix scenario as optimal, achieving reductions of 59.29% in CO₂ and 81.34% in NOx. Key measures included battery-electric trucks (transportation), building envelope retrofits (buildings), and photovoltaic power expansion (electricity). The comprehensive implementation of selected technologies could lead to reductions in both PM2.5 and NO2 concentrations by 6% and 24%, respectively, although wintertime ozone levels would increase by 10%. The findings highlight the need to strengthen targeted end-of-pipe control measures for dust and volatile organic compounds (VOCs) alongside carbon reduction efforts, in order to maximize the co-benefits of climate change mitigation and air quality improvement.
