AIR TRAVEL
Calculating air travel is not a simple as one may think. There are different times in a flight where the amount of fuel used varies.
Our air travel calculator takes into account fuel used taxiing the runway, on take-off, and while landing, as well as during level flight.
Simple Option
We have developed a number of easy options for you by investigating average distances for one-way flights.

Using the state level averages for energy use and state greenhouse factors for fuels, the formula to estimate your carbon emissions takes into consideration the stand-by and running emissions of your equipment, and the state variable carbon emission coefficient per person.
We have also included the carbon emission factor in regard to personal waste. The calculation is based on the average municipal solid waste figure for carbon emissions per person multiplied by the number of employees in your business.
This simple option is based on state averages, however we know that not every business is average! The detailed method allows you to customise the calculation to your business� consumption.
Detailed Option
The best and most accurate method to customise your calculations is based on your business usage of energy over the past year. By entering the figure that you consumed (eg. kWh for electricity, MJ for gas, L for LPG and tonnes for wood), the emission calculation will be more candid and accurate for you. This is on your energy bills, but if you can’t find them, ring your energy retailer: they should be able to give you this information.
We’ve used greenhouse coefficients from the Australian Greenhouse Office Factors and Methods Workbook 2006 to convert the energy use information into greenhouse gas emissions. We use these coefficients on a state-by-state basis so to help you make a more accurate calculation, for example Tasmania have a minimal carbon emission in comparison to mainland Australia with regard to electricity however have significant emissions in comparison with regard to wood and LPG.
With regard to wood, our calculations are based on the assumption that it is sourced sustainably and burnt efficiently in a wood heater.
In this option, if you are buying Green Power or Green Gas, we give you the option to tell us what proportion of your usage is from an accredited green source, because you won’t have to offset that part of your energy use – it’s already zero emission! If you’re unsure, check www.greenpower.gov.au or contact your energy retailer.
