本研究は中国の自家用車のエネルギー需要と排出量を省別にモデル化し、異なるシナリオ下での脱炭素経路と電力部門への影響を評価した。車両電化による電力消費増加はV2Gによって相殺され、累積発電排出の半分以上をオフセットできることを示した。地域差も顕著で、東部で排出が高い。
English
This study establishes a provincial bottom-up model for China's private vehicles to calculate energy demand and carbon emissions, evaluating decarbonization paths and impacts on the power sector. It finds that vehicle electrification raises electricity consumption, but V2G can offset over half of cumulative power generation emissions. Significant regional disparities exist, with eastern China having higher emissions.

日本のGX文脈において
中国のEV普及とV2Gの効果を省別に実証した本論文は、日本でも進む電動化と電力系統の連携政策（例えばV2G実証）に示唆を与える。特に、2040年以降の自家用車保有台数減少や効率改善の影響は、日本の長期エネルギー需給見通しにも参考となる。
In the global GX context
This paper provides strong empirical evidence on the interaction between transport electrification and the power sector, highlighting V2G's role in mitigating carbon shifting. It contributes to global discussions on cross-sector coordinated emission reduction, relevant for TCFD/ISSB-aligned scenario analysis and transition planning.

📄 Abstract（原文）
China’s road transport, especially private vehicles, has experienced continuous growth in energy consumption and carbon emissions in recent years. Electrification-driven net-zero pathways and their impacts on the power sector have drawn broad concern. Current research insufficiently explores vehicle-to-grid (V2G) advantages and fails to update data and assumptions aligned with the latest policies. This study establishes a provincial bottom-up model to calculate the energy demand and carbon emissions of private vehicles and evaluates decarbonization paths and their impacts on the power sector across different scenarios. Private vehicle ownership will rise first and then fall, hitting around 453 million by 2060. Near-term improvements in energy efficiency combined with the long-term diffusion of new energy vehicles can drive private transport toward net-zero emissions after 2050. Vehicle electrification raises electricity consumption remarkably, whereas V2G effectively mitigates carbon shift and offsets over half of cumulative power generation emissions. Marked regional disparities prevail in vehicle usage and emissions, with eastern China presenting higher values compared with western regions. Decarbonization of road transport is more than just addressing carbon shifting, and V2G facilitates cross-sector coordinated emission reduction. Future research is needed to explore the technical, economic and institutional potential for deepening decarbonization.
