Buyer’s Guide

Using the Buyer’s Guide

What the Buyer’s Guide shows
The Buyer’s Guide displays vehicles in the top 25% for greenhouse emissions  in each class, calculated from the range of rated greenhouse emissions from best to worst in that class. So if you select the class of vehicle that suits your needs, it will tell you which ones are the best from an environmental perspective.

LEV Green Tick
Vehicles in each class whose emissions ratings come within 25% of the best performer in that class are illustrated with an ‘LEV green tick’, as examples of the very best available.

Buying a New Vehicle?
The Buyer’s Guide will help you to select a suitable vehicle to meet your needs:
• size and type of vehicle (class)
• Usage (city or highway)

City v Highway Driving
The rating for assessing greenhouse emissions currently uses a laboratory test that assumes a set combination of city and country driving. In the near future, separate cycles for city and country will become available and enable vehicle assessment based more closely on individual usage.

City Driving
If you mainly drive in the city, then for the same type of vehicle and performance a hybrid-electric car may suit your needs.
Hybrids automatically shut off the engine when the vehicle stops, and starts it again seamlessly when needed.

Highway Driving
New generation turbo-diesel engines feature regularly amongst the most fuel-efficient in each class. For the same performance as a comparable petrol-fuelled vehicle, a modern diesel can deliver up to 30% better fuel efficiency. This translates into a 25% reduction in CO2 greenhouse emissions.

Emission and Fuel Consumption Ratings

Greenhouse Rating (in grams CO2 per km)
This is the rated CO2 emissions based on the fuel consumption test using mentioned below. Fuels vary in carbon content so the fuel consumption figure is multiplied by a conversion figure for each fuel.

Fuel Consumption (in L/100km)
The figures quoted are from a laboratory test intended to mirror real-world driving cycles. In practice it may be unrealistic to expect to achieve these figures, but they are valuable for comparison purposes. (NB: the Green Vehicle Guide replaces the Fuel Consumption Guide that previously provided this information.)

Air Pollution Rating
(Based primarily on regulated emission standards) — to help you compare a vehicle’s contribution to urban air pollution (and associated impact on the environment, human health and amenity).

Source of Data
All data on vehicle fuel consumption, air pollution and greenhouse ratings is drawn from the Australian Government Green Vehicle Guide

While the Green Vehicle Guide provides comprehensive ratings based on air pollution and greenhouse emissions for all vehicles available on the Australian market, only shows the best performers from a greenhouse point of view.

Vehicle not Shown?
If a vehicle you are interested in is not shown then it must not be in the top 25% greenhouse performers in that class. If you wish to find out about its emissions then you will need to look it up on the Green Vehicle Guide at

Why should I buy a Low Emission Vehicle?

Climate change represents the greatest challenge to human civilisation for the foreseeable future and is occurring as a result of man-made emissions of greenhouse gases at a rate far beyond what would occur naturally.

Transport is the second largest source of greenhouse gas emissions of all economic sectors in Australia, behind those from stationary energy (i.e. power stations). In addition to this, emissions from transport have the highest growth rate of all sectors. Because of the urgent need to reduce greenhouse gas emissions overall, it is imperative that emissions from transport not only be stabilised, but dramatically reduced.

The responsibility to reduce emissions from personal transport must be borne by us all. In choosing a Low Emission Vehicle, you are making an important contribution to the fight against man-made climate change.
