Abstract
The improvement of air quality not only promotes resident wellness but also decelerates climate change. The relationship between electric vehicle (EV) adoption and air quality is considered a useful indicator for the state government to evaluate the effectiveness of the EV Sales Tax Exemption Policy and further enact a package of benefits / restrictions for future environmental protection.
This study demonstrates current trends in EV adoption and air quality over time and over different geographic regions via analyzing the data of EV adoption rate and total vehicle amount (including EV and non-EV) from all counties in Washington State. The analysis presents that King County has a high EV adoption rate, but lower air quality compared to Garfield County, where fewer EVs exist, but air quality is much better. This suggests that more than simply increasing EV adoption may be required to improve air quality since high traffic volume still negatively impacts air quality.
