Environment Quality intensity substances is based on five
aspects: ground-level ozone,
particulate matter, carbon
monoxide, sulfur dioxide, and
nitrogen dioxide.

Singapore’s 2020 air quality targets are benchmarked against the World Health Organisation’s (WHO) Interim
Targets and Air Quality Guidelines. For SO2 and PM2.5, Singapore’s Sustainable Blueprint 2020 annual targets are

15μg/m and 12μg/m respectively.
Singapore adopts the Pollutant Standards Index (PSI). Pollutant Standards Index (PSI) is based on 6 air pollutants
(SO2, PM2.5,PM10, CO, Ozone and NO2). In 2015, air quality based on the PSI was within the “Good and Moderate”
range on 87.5% of the days and in the ”Unhealthy” or worse range on 12.5% of the days.
