Abstract:
The global shift toward renewable energy and the wide adoption of electric vehicles (EVs) are expected to mitigate a series of global environmental concerns, while few studies have focused on their contribution to reducing PM2.5 concentrations. This study investigates the temporal evolution of secondary inorganic aerosols (SAIs, sulfate and nitrate) and their gaseous precursors (SO2 and NO2) in Guangdong from 2014 to 2024. By integrating multisource datasets, including air pollutant monitoring, aerosol chemical composition, energy use, and EV statistics, this study quantifies the contributions of coal consumption reduction and clean energy growth to SO2 mitigation, and further examines the association between transportation electrification and NO2 decline. Meanwhile, the changes in the sulfate-to-nitrate ratio and aerosol acidity are also analyzed, highlighting the role of evolving atmospheric chemistry in shaping PM2.5 composition and guiding future emission control strategies.
