This results in serious congestion. In Central, the average car speed is only at 10km per hour, which is slightly faster than jogging. To make matters worse, Hong Kong's claustrophobic urban structure traps roadside emission, causing street canyon effects. Making the city unwalkable, thus further increasing the reliance on pollutant-emitting transportations.
Starting from 2011, air pollutants like sulphur dioxide, PM2.5 and nitrogen dioxides from vessels emissions is higher than that of power plants. Citizens who live along the coast-side such as Tsuen Wan, Kwai Chung and Kwai Chung are especially affected. According to study by Civic Exchange, 385 premature deaths are caused by ship emission alone annually in Hong Kong.
Especially in winter when the wind is blown easterly from China, pollutants are brought to Hong Kong. While Hong Kong is affected by air pollution from China, 53% of the time, the dominant sources of Hong Kong’s air pollution are local.
