Fact:

Diesel versions are usually more fuel-efficient than petrol versions of the same car model. However, they emit greater air pollution rating — the one-star list is entirely made up of diesel vehicles, mainly large 4WDs. Why go green?

Driving Tips

Bundle Errands
When you start your car after it's been sitting for more than an hour, it pollutes up to five times more than when the engine is warm. That's why combining errands into one trip is more effective and reduces air pollution. If you go out to do your errands all at once, your engine will remain warm, emitting less than when starting it hours apart for separate errands. This means more time on your hands, less traffic congestion and less pollution - which all add up to cleaner air. So make a list, plan your route and bundle your errands. You'll be saving a lot more than just time.
Save Fuel by Slowing Down
Hard acceleration and braking can waste fuel and lower your kilmoetres travelled by 33% on the highway and 5% around town. To improve fuel economy and reduce greenhouse gas emissions, go easy on the brakes and accelerator, reduce time spent idling, and use cruise control on your car if you have those features. Hard acceleration and braking can also waste fuel and lower your mileage by 33% on the highway and 5% around town.
Get Rid of Unnecessary Weight
Avoid keeping unnecessary items in your vehicle, especially heavy ones. An extra 45kg in your vehicle could reduce the amount of kilometres you get out of a litre, by 2% or more for small cars. A roof rack or carrier provides additional cargo space and may allow you to meet your needs with a smaller car. However, a loaded roof rack can decrease your fuel economy by 5%. Reduce aerodynamic drag and improve your fuel economy by placing items inside the boot whenever possible.
 
Maintain Your Car Regularly
A well-maintained vehicle produces 20% less ozone-related emissions, saves money on fuel, and means less traffic congestion due to breakdowns. If all Australians kept their tyres properly inflated, fuel use nationwide would come down. AA car service could boost your kilometres per litre anywhere from 4 to 40%; a new air filter could get you 10% more kilometres per litre.
Choose an Efficient Vehicle
Road traffic is a major cause of air pollution in urban areas and is also responsible for about 13% of Australia's carbon dioxide and other greenhouse gas emissions. The amount of carbon dioxide a car produces is directly linked to the type of fuel it uses and its fuel consumption.
With fuel prices on the rise, a fuel-efficient model also means more money in your pocket: for every 10,000 km you drive, each L/100 km less fuel your car consumes than another models, saving you $130 (based on a fuel price of $1.30).
