This online calculator can be used to estimate most* annual direct and indirect greenhouse gas emissions. This calculator is not designed to replace a comprehensive Carbon Footprint Analysis but to give the user a good indication of the most common greenhouse gas emitting activities.
Gathering Information - You will be required to gather information from sources like electricity bills, vehicle log books and travel agent spreadsheets. If you have difficulty, averages are often available to make it easy.

*Contact us for our 'excel calculator' if you wish to calculate emissions not shown (for example freight, staff travel, office consumables other than paper, water, aviation fuel and fridge/chiller (fugitive) emissions).
Assumes an annual travel period
Assumes annual travel distance of 15,000 km
Includes Scope 1 (direct) and Scope 3 (indirect) emissions
The emission factor used is the weighted average for all Australian States.
Assumes weekly collection frequency
If your type of paper is unknown, select Virgin
The average A4 reem of 80gsm weighs 2.5kgs
'Short Haul' uses Melbourne to Brisbane
'Medium Haul' uses Sydney to Singapore
'Long Haul' uses Melbourne to London (via Doha)
An uplift factor of 9% is used to account for indirect routes and delays / circling of planes.
What is Radioactive Forcing Index (RFI)?: The IPCC (Intergovernmental Panel on Climate Change) has identified that aircraft emissions at altitude have a greater impact on the atmosphere due to other non-CO2 climate change effects from aviation (e.g. NOx, water vapour, contrails) and the RFI factors allows for these other impacts
Use 'Average Passenger Load' for off-peak travel
When calculating your event emissions, include other calculations such as travel, electricity, waste, and so on and add to a saved calculation to get the total emissions for an event.
Emission factors are updated regularly to industry standards. For details of the sources used in this calculator, please see About Our Calculator.
