What is Mt CO₂-e? Emissions are a combination of gases. Most are Carbon Dioxide (CO₂). The other gases are measured as a Carbon Dioxide equivalent (CO₂-e) based on the amount of heat they trap in the atmosphere. They’re measured in Million Tonnes (Mt).

Australia has legislated targets for greenhouse gas emissions.

  • 2030 Target: 43% lower than 2005
  • 2050 Target: Net 0 Mt CO₂-e

This data helps you track progress to those targets. 

It shows Australia's yearly net emissions and how they compare with 2005.

Several factors affects transport emissions across Australia's states and territories, including population size, urban planning, geographic challenges, and transport policies.

Despite its lower population, WA has considerable transport emissions due to long travel distances and a strong dependence on road and air transport, especially in remote areas.

Transport is Australia's second-biggest greenhouse gas emitter, after electricity.

'Road' is the biggest category in transport emissions, by far. When we drill down into 'road' emissions, cars dominate. Just 2% of Australia's 21 million registered vehicles are electric.

That figure is growing. But something else has changed. There are more diesel vehicles on the roads too.
