Does the Popularization of New Energy Vehicle Facilitates the Improvement of Air Quality? Taking China as Evidence

Automobile exhaust always makes up a significant portion of the causes of air pollution, and new energy vehicles (NEV) are being investigated as a potential solution to the problem of urban air pollution. Through a number of policy incentives and infrastructure improvements, the Chinese government encourages the quick development of the new energy automotive sector. National air quality has also improved dramatically in recent years. In this context, the primary goal of this study is to explore whether there is a significant positive correlation between the popularization of NEVs and air quality. This study looks for data on the penetration rate of NEVs in various provinces and cities across the country, as well as the data on the number of days with air quality, and makes a visual chart to show the change trend from 2013 to 2022. Finally, policy recommendations are given. The government should adapt to local conditions and continue to boost the infrastructure of NEVs. In addition, clean energy power generation, sustainable production and recycling should be actively promoted from the perspective of the whole life cycle of NEVs
