Transboundary smoke haze from the land and forest fires in the region are also problems which affect Singapore’s air quality intermittently during the South West Monsoon period from August to October.
Integrated urban and industrial planning, as well as development control, has enabled the government to put in place preventive air pollution control measures during the planning stage. In addition, legislation, strict enforcement programmes and air quality monitoring have helped to ensure that air quality remains good despite our dense urban development and large industrial base.
As such, Singapore enjoys an air quality better than many cities in Asia and is comparable with the air quality of US and European cities. We have also been faring well, with the PSI in the ‘Good’ and 'Moderate' range 97% of the time in 2014.
Singapore's air quality targets, sulphur dioxide emission inventory, industrial and vehicle emission standards are detailed below.
