Rethink transport choices. Walking or cycling are healthy options.
People are using more cars more often. Over the last 20 years Sydney's population has grown by 21 per cent, the number of car trips has increased by 41 per cent and the number of cars by 58 per cent. If we continue like this for the next 25 years, we stand to undo any gains we've made in air quality through controls on industry, business and household emissions.
In Sydney alone, motor vehicles create the following emissions:
- 71 per cent of NOx (oxides of nitrogen)
- 38 per cent of VOC (volatile organic compounds)
- 12 per cent of PM10 (particles <10µm in diameter)
- 18.5 per cent of PM2.5 (particles <10µm in diameter).
The direct cost of driving for households are large, with transport taking up almost as much of the household budget as food. It goes to show just how much we have come to rely on cars.
Sitting in cars instead of walking or cycling also stops us from being healthier.
By rethinking our transport choices and reducing the number of trips we make in the car, we can save money, improve our health and the environment.
