About the document

Australia’s National Greenhouse Accounts are made up of a series of comprehensive reports and databases that estimate, and account for, Australia’s greenhouse gas emissions. These publications fulfil Australia’s international and domestic reporting requirements.

The national inventory is prepared according to the framework of rules supporting the United Nations Framework Convention on Climate Change (UNFCCC) and the Kyoto Protocol. All parties to these agreements must use the UNFCCC Reporting Guidelines on Annual Inventories and the supplementary reporting requirements under the Kyoto Protocol to prepare their national inventories. These guidelines establish standardised reporting formats and require detailed information on all aspects of each party’s national inventory system, including measurement systems, data collection systems, estimation methodologies, reporting and data management.

The ‘Quarterly Update’ is a publication series that reports on the latest estimates of Australia’s national greenhouse gas inventory.

Annual emissions (excluding emissions from land use, land use change and forestry) for the year to September 2013 are estimated to be 542.1 Mt CO2-e, which represents a 0.3 per cent decline on emissions from the previous year.

NOTE:

The Quarterly Update of Australia's National Greenhouse Gas Inventory September 2013 refers to an increase in cement emissions of 6.4 per cent over the previous year. This finding derives from an ABS data source that has been superseded by a newer, more specific source that more accurately reflects domestic cement clinker production.

The Department acknowledges that if the newer ABS data source is used, emissions from domestic cement production are likely to be assessed as falling rather than increasing.

The net effect of the change is expected to be minor - a decline of 0.4 Mt CO2-e in emissions or less than 0.1 per cent in the national inventory total.
