The Emissions Audit tracks Australia’s emissions of greenhouse gases from the combustion of fossil fuels – this issue contains data up to the end of September 2017. The Emissions Audit will therefore give readers the most up to date possible advice on how Australia is tracking towards meeting its emissions reduction commitment under the Paris Agreement.

Fossil fuel combustion accounts for the majority of Australia’s emissions – 71% in Australia’s most recent National Greenhouse Gas Inventory, which was for the year 2014-15. Fossil fuel combustion emissions also account for most of the year on year change in Australia’s emissions. Over the last few years the change is an increase.

The National Energy Emissions Audit is published on a quarterly basis, in September, December, March and June each year, with data to the end of the preceding quarter. Each month the Electricity Update of the Emissions Audit is produced, reporting on changes to emissions from electricity generation in the National Electricity Market (NEM), and including commentary on other issues relating to the extraordinarily dramatic changes happening in Australia’s electricity supply system.

All emissions data are reported as annual moving averages. This approach removes the impact on the reported data of seasonal changes, which particularly influence electricity and gas consumption. Annualised data will show a month on month increase if the most recent monthly quantity is greater than the quantity in the corresponding month one year previously.

Most data are presented in the form of time series graphs, starting in June 2011, i.e. with the year ending June 2011.
