The main causes of Hong Kong’s air pollution are oil- and coal-fired power stations and vehicle exhaust emissions.
Hong Kong’s air pollution is only getting worse as we consume more and more energy.
The government’s way of judging air pollution, its “Air Quality Objective” (AQO), has not been updated for 20 years and now lags far behind World Health Organization safety guidelines. That’s why the Hong Kong government’s Air Pollution Index, which they publish every day, does not give a true picture of the air quality and is endangering your health.
