Data from the NSW Government’s air quality monitoring network show that air quality in NSW during 2015 was good by international standards. The Air Quality Index was in the very good, good or fair category for at least 95 per cent of the time in the Sydney and Hunter regions and close to 100 per cent of the time in all other regions, demonstrating that air quality consistently meets relevant standards.
There were no exceedances of the nitrogen dioxide, sulfur dioxide and carbon monoxide standards, with levels remaining well below the relevant standards. Ozone and particle levels occasionally exceeded the national standards in some areas.
