Data confidence level:
This FACT indicates the carbon emissions - a form of greenhouse gas - in each state and territory in 2009. This data is represented in millions of tonnes per 100,000 people. The state with the highest number of carbon emissions is the Northern Territory at 14 million tonnes per 100,000 people. The state with the least is the Australian Capital Territory at 0.28 million tonnes: unsurprising given its small population and lack of mining or agricultural activity.
