Abstract

Electric vehicles (EVs) have been an effective technology option for sustainable futures among many countries. Since 1994, the HKSAR government has been promoting electric vehicles and developing related infrastructure to encourage local people to purchase EVs, and until 2010, the number of EVs began to increase. However, it is questionable whether the large-scale use of electric vehicles that rely on the grid can help reduce greenhouse gas emission (GHG), because most parts of the world still rely on fossil fuels for power generation. The use of electric vehicles will increase the regional power supply and demand relationship, so it is necessary more fossil fuels are used to generate electricity than before. This article aims to explore the relationship between the promotion of electric vehicles in Hong Kong and Hong Kong’s greenhouse gas emission with reference to the development of electric vehicles in recent years, Hong Kong’s air quality and air pollution emissions. The results show that despite the increase in the number of vehicles and kilometres driven in recent years, there has been a significant improvement in air quality and a substantial reduction in air pollutant emissions due to the increase in the share of electric vehicles in Hong Kong.
