The algorithm used to perform this analysis is based on the average fuel consumption, the vehicle type, and the annual kilometres travelled.
With regard to the average fuel consumption, this varies according to the type of fuel and the size of the vehicle. We have researched the four common fuel types for vehicles – petrol, LPG, Diesel, and Natural Gas. The reason for the variance is due to the differences in carbon content, energy content and varying efficiency with which fuels are used, hence the variation in greenhouse gas emissions per fuel type.
The values for fuel consumption we have used are averages based on the vehicle size. You can find model-specific information at www.greenvehicleguide.gov.au. For comparison, the Australian Bureau of Statistics (ABS) vehicle survey for 2004-05 shows average passenger vehicle fuel consumption at 11.7 L/100 km and for motorbikes, 5.8 L/100km.
Using a greenhouse coefficient, we are able to calculate the greenhouse gas emissions for small to large motorbikes, scooters, hybrid cars, small/medium cars, 6 cylinder/V8 Cars, small/medium/large 4WD’s, and vans & light commercial vehicles.
It’s our objective to analyse the average fuel consumption figures on an ongoing basis to assure that our calculations are as accurate as they can be. We are informed that, in the near future, a new Australian Government study comparing Australian government test results to average fuel consumption will be released and, when available, it will be included in our methodology.
We are also committed to investigating other fuel sources including the popular ethanol option.
