The most common greenhouse gases are carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons and sulphur hexafluoride.
Emissions from these gases are reported under the Kyoto Protocol (an international treaty designed to limit global greenhouse emissions) and are aggregated into carbon dioxide equivalents (CO2 -e) using factors called global warming potentials (GWPS).
The Department of Climate Change and Energy Efficiency publishes a number of reports that together, constitute the Australian National Greenhouse Accounts.
