Roadside Emission

Uncontrolled car growth is the main reason for severe roadside pollution.

Up till 2015, Hong Kong has over 820,000 cars.

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.
Ship Emission

Hong Kong is one of the world’s top busiest container ports.

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.
Regional pollution

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.
