Emissions Revisions

Explainer

Australia’s reported greenhouse gas emissions are often revised in later reports. This page tracks every version of reported emissions in the quarterly inventory updates.

How to read these charts: The lines show Australia's reported emissions in million tonnes of Carbon Dioxide equivalent (Mt CO2-e). Each line represents the date they were reported. Click on the categories in the legend to deselect.

Acknowledgment: This topic was inspired by Ketan Joshi, an author and communications consultant who focuses on climate. The chart concepts below also come from him.

Revisions to Land Use

Explainer

This section highlights revisions to estimated emissions in Australia's Land Use sector.

Upshot: Recalculations in the Land Use sector have removed an extra 48.9 Mt CO2-e each year since June 2021. 

The calculator used to model Australia’s greenhouse gas emissions from the land sector is called the Full Carbon Accounting Model (FullCAM). DCCEEW has addressed these recalculations and changes in the FullCAM model in various reports.

Revisions to Other Sectors

Explainer

While the Land Use sector is the most contentious, all sectors in the Greenhouse Gas Inventory are subject to revisions. The following charts show revisions to estimated emissions for other sectors.

How to read these charts: The lines show Australia's reported emissions in percentage terms, where the percentage reflects current emissions compared with the baseline year (2005). This allows you to see how much each revision contributes to the big picture - that is, reducing Net Emissions by 43% by 2030.
