Outline
To evaluate the greenhouse gas (GHG) emissions and mitigation potential in the transportation sector of Henan Province, localized vehicle emission factors were calculated based on the COPERT model. A 3km × 3km gridded emission inventory was established using ArcGIS, and the spatiotemporal dynamics of vehicle-related GHG emissions were systematically analyzed. Vehicle ownership in Henan Province from 2025 to 2035 was forecast by combining the Gompertz function with the elasticity coefficient method, and emission trends under multiple policy scenarios were examined. The results showed that total vehicle GHG emissions increased from 140 million tonnes to 160 million tonnes during 2019 to 2023, with an average annual growth rate of 2.9%. Carbon dioxide (CO2) accounted for more than 98% of total emissions, while light-duty passenger cars and heavy-duty trucks were identified as the primary contributors. Urban road traffic was responsible for 78.8% of total emissions, and high-emission areas were concentrated in core cities such as Zhengzhou and Luoyang, presenting a spatial pattern of central clustering and peripheral diffusion. Under the baseline scenario, total GHG emissions were projected to reach 170 million tonnes by 2035. In contrast, when new energy vehicle promotion, green commuting, and accelerated retirement of aging vehicles were jointly implemented, total emissions were reduced to 70 million tonnes, representing a 58.1% decrease compared with the baseline. These findings provided quantitative evidence to support carbon management and the optimization of mitigation pathways in the transportation sector of Henan Province.
