About Melbourne’s air quality

Generally, air pollution levels vary from year to year because of weather changes. Since EPA began measuring Melbourne’s air quality in 1973, it’s continued to improve. Improvements and air quality can also vary from suburb to suburb due to local pollution sources.

Emissions controls on vehicles and industry have led to improved air quality in Melbourne. Removal of lead from petrol has meant reduced lead in the environment. Carbon monoxide and nitrogen dioxide levels in the air have also fallen over the past 30 years.
