Electric vehicles (EVs) signify a pivotal transition towards sustainable transportation, providing considerable environmental and economic advantages. Nonetheless, the substantial initial expenses and infrastructure obstacles persist in obstructing their extensive implementation. This study examines the impact of financial incentives in sustainable government policies on increasing electric vehicle use. The research highlights essential financial instruments—such as purchase subsidies, tax rebates, and fee exemptions—that effectively promote consumer adoption of electric mobility through a comparative review of global policy models. The research assesses the impact of design, accessibility, and consistency of these incentives on adoption rates in various socio-economic circumstances. The findings seek to assist policymakers in developing innovative, equitable, and effective financial measures to expedite the transition to sustainable transportation.
