In alignment with China's strategic dual-carbon goals; this paper aims to investigate the potential for energy saving and emission reduction in the road transportation system of coastal urban agglomerations. Taking the coastal urban agglomerations in Fujian Province as an example; a long-range energy alternatives planning system model (LEAP) has been constructed; three primary scenarios and four secondary sub-scenarios have been developed. The emission reduction potential and trend of regional road traffic were studied by adjusting the parameters of vehicle ownership and fuel economy. The study indicates that among all scenarios; the Modified Policy Scenario (MPS) demonstrates the most superior energy saving and emission reduction effects; with the greatest potential for energy conservation and emission reduction. Compared to the Business as Usual (BAU) scenario; the energy saving of the MPS is expected to be improved by 59.3%; by 2035. Under the MPS scenario; the trends in greenhouse gas and pollutant emissions both show a significant decline; with remarkable emission reduction effects. Looking specifically at the energy- saving and emission reduction potential of different vehicle types; under the MPS scenario; small- duty gasoline passenger vehicle (SGPV); heavy-duty diesel freight vehicle (HDFV); and light-duty gasoline freight vehicle (LGFV) have the greatest potential for energy conservation; carbon emissions from 8 types of vehicles can peak by 2025; and pollutant emissions can be effectively controlled; with the greatest potential for pollutant emission reduction found in HDFV. The research confirms that advancing the implementation of comprehensive policies; accelerating the phase-out of traditional fuel vehicles; and optimizing the structure of road vehicles will have a positive impact on the realization of the green and low-carbon goals. Through model simulation; it is anticipated that the road traffic system of the coastal urban agglomerations in Fujian Province will achieve significant energy-saving and emission-reduction effects before 2030. © 2024 Science Press.
