- Energy (including stationary energy, transport and fugitive emissions)
- Industrial processes
- Solvent and other product use
- Land use, land use change and forestry (LULUCF)
See how much Australia emits for information on Australia's emissions in each of these sectors, and descriptions of the sectors. Note that emissions for any particular industry may span more than one of these sectors. For example, emissions from aluminium smelting are accounted for in the industrial processes sector while the fuel combusted for energy in the production process is accounted for in the energy sector. Similarly, for the agricultural industry, emissions from fuel combustion are reported under energy, while emissions from agricultural processes (for example enteric fermentation) are recorded under agriculture.
Australia's greenhouse gas inventory
Australia’s greenhouse gas emissions are reported in the following publications:
- Australia reports emissions under the above sectors to the UNFCCC in its annually updated National inventory report.
- Under reporting provisions applicable to the Kyoto Protocol, Australia also publishes the National greenhouse gas inventory, which includes emissions from 'Solvent and other product use' in the 'Industrial processes' sector.
- Emissions grouped by economic sector are reported in the National inventory by economic sector.
- Emissions grouped by state or territory are reported in the State and territory greenhouse gas inventories.
Australia's greenhouse gas accounting methodologies
Australia has developed a national reporting system for greenhouse gas and energy accounting. The reporting data for businesses provided by this system will be essential for the operation of any eventual emissions trading scheme in Australia. The reporting framework is established by the following tools:
The Department of Climate Change has published the following guidelines to assist businesses in understanding their participation and reporting obligations under the NGER Act and how to apply the accounting calculations detailed in the NGER Determination:
Australia's carbon accounting methodologies follow international guidelines and are reviewed and updated annually. They are consistent with the 2006 IPCC Guidelines for National Greenhouse Gas Inventories.
