Emissions of greenhouse gas are reported in ways which may be confusing. Internationally, emissions are reported on a carbon basis. If emissions are reported as carbon, multiply by 3.67 to get the equivalent in carbon dioxide emissions. Emissions also are reported on a carbon equivalent or carbon dioxide equivalent basis. This means that all greenhouse gases have been converted to the equivalent of either carbon or carbon dioxide based on the gases global warming potential. A tonne of methane equals 21 tonnes of carbon dioxide. A tonne of nitrous oxide equals 320 tonnes of carbon dioxide.
