Farming Enterprise Greenhouse Gas Emissions Calculator

Help and Information

The greenhouse gas calculator has been developed to provide an estimate of farm-based emissions in Queensland. Whilst based on best available information, it is not definitive and should be used for information only as there is an element of uncertainty associated with estimating greenhouse gas emissions from agricultural enterprises and ecosystems.



All emissions are represented in relation to carbon dioxide and its Global Warming Potential (GWP) and expressed as carbon dioxide equivalents (CO2-e). Carbon dioxide (CO2) is produced on combustion of fuels and during cultivation of soils. Methane (CH4) is a gas produced by animals and has a Global Warming Potential equivalent to 23 times CO2 molecules. Nitrous oxide (N2O) is emitted from nitrogen sources, including fertilisers, urine and dung and has a Global Warming Potential 296 times that of CO2. CO2-e = 1 * CO2 emitted + 23 * CH4 emitted + 296 * N2O emitted.
