The transportation sector is pivotal in global decarbonization efforts, given its significant contribution to greenhouse gas emissions. This paper examines the challenges hindering the widespread adoption of electric vehicles (EVs) and the policy responses to address these barriers. Despite advancements in EV technology and an increase in global EV sales, adoption rates in the U.S. remain low due to high upfront costs, range anxiety, and insufficient public charging infrastructure. The study analyzes various financial incentives, such as tax credits and rebates, and the impact of these policies on EV adoption. It also highlights the importance of expanding EV charging infrastructure, reviewing federal and state initiatives aimed at enhancing the availability and accessibility of charging stations. By comparing international policies and their effectiveness, the paper provides insights into potential strategies for overcoming obstacles and promoting sustainable transportation in the U.S.
