Promoting policies on eco-friendly cars is a major policy tool to reduce air pollution in cities. This study analyzed the consumer’s purchase intention on electric vehicles and how air quality problems such as particulate matters affect their purchase intention using ordered logit model from a survey with 918 drivers in Korea. The results show that major factors that significantly affect the purchase intention on electric vehicles are the interest in new technologies, the concerns on environmental problems issues, and the awareness of characteristics of electric vehicles. Especially regarding air quality issues, consumers who are more interested in climate change or environmental pollution are more likely to purchase electric vehicles as they recognize the importance of activating electric vehicles as a solution to particulate matter. In order to spread electric vehicles in the future, it is important to actively promote electric vehicles that can improve consumer awareness of eco-friendly electric vehicles and to make technical and policy efforts to improve the eco-friendly nature of electric vehicles such as expanding renewable energy.
