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.

    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
