Carbon Dioxide Emissions Calculator

Carbon calculator usage instructions

• The calculator uses emissions factors which take account of all greenhouse gases (i.e. CO2, N2O, methane etc.) released by the activities, with the results presented in units of metric tonnes of CO2 equivalent (CO2e). In most cases that means the results will be slightly higher than if calculating CO2 only. The calculations of emissions from fuels are Scope 1, meaning the direct GHG emissions from the combustion of the fuels. The calculations do not include the Well to Tank (WTT) Scope 3 Emissions associated with extraction, refining, distribution, storage and retail of the fuels.
• For electricity usage, emissions factors provided for free include both Generation and Transmission and Distribution (T&D) losses. The calculations do not, however, include the Well to Tank (WTT) Emissions associated with extraction, refining, distribution, storage of the fuels used in the power stations.
• When calculation emissions for Wood in the calculators the emissions factors for Wood Pellets is used. The calculator also assumes domestic coal is used in both the Business and Household calculators.
• if you are calculating your car travel emissions then enter the total distance you have travelled over the past 12 months.
