Across New South Wales, air pollution stems from a variety of sources, including dust, bushfires, pollen, the fossil fuel industry, and motor vehicles. However, in Sydney, motor vehicles are the primary contributors, accounting for the largest share of emissions that adversely affect public health.

The health impacts of traffic pollution are both significant and far-reaching. It has been strongly linked to serious conditions such as cardiovascular and respiratory diseases, as well as various forms of cancer. Additionally, its effects extend to reproductive, urological, and neurological systems, highlighting the pressing need to reduce vehicle emissions and improve air quality for the well-being of all.

Vehicles contribute 14% of PM2.5, and 62% of nitrogen oxides to the NSW pollution level, but those built after 2013 emit 97% less oxides of nitrogen than those built in 1976.

In NSW in 1976, there were 2.2 million motor vehicles  and today we have 5.2 million.

Improving the emissions standards for each vehicle has not been enough to reduce pollution rates across NSW.  Vehicle numbers continue to rise, increasing by 2% increase between 2017 and 2018.

The local environment also contributes to how this pollution travels. Sydney’s location within a basin means the cool overnight air moves the pollution from vehicles and industry from the outer Western Suburbs towards the Eastern Suburbs on the sea.

Morning sea breezes then move the pollution back towards the Western Suburbs, creating smog. Without strong wind or rain, this pattern will continue and pollution will build up.  

The build up of pollution can be further exacerbated by heat not being able to escape as the average air temperature increases.

In highly urbanised environments, with little tree cover, this can increase the temperature by a few degrees.  In the City of Parramatta on a summer’s day, the CBD can be sitting at 40 degrees while Parramatta Park is at 30.   

"Air pollution has far-reaching consequences that impact the entire community," said General Manager of Public Affairs, Bastien Wallace. "By choosing to ride or walk short distances instead of driving, we can significantly reduce motor vehicle pollution and contribute to a healthier, more sustainable environment for everyone."

Bicycle NSW encourages people to switch to bike riding for car journeys under 10 minutes, or commutes to work under 10km.  

Your heart and wallet will thank you, you may get there quicker and you’ll help us all breath easier.
