Where do Australia’s greenhouse gases come from?
In 2008, the main sources of Australia’s greenhouse gas pollution were1:
- 72% from energy, including
- stationary energy (mainly electricity generation) 51%
- transport 14%
- fugitive emissions (emissions from fossil fuel mining, like oil and gas production) 7%
- 15.9% from agriculture, mostly from cattle and fertilisers
- 5.7% from industrial processes (for example, aluminum and cement production)
- 4.6% from land use, land-use change and forestry (LULUCF)
- 2.6% from waste.
Australia’s emissions, excluding LULUCF, have substantially increased from 418 Mt CO2-e in 1990 to 550 Mt CO2-e in 2008, which is an increase of 31.4%
(Mt Co2 e – megaton of carbon dioxide equivalent- the amount of greenhouse gas effect produced by all types of greenhouse gases as if they were the same “i.e. equivalent” to CO2)
The main reasons for the increase in Australia’s emissions are:
- Stationary energy – up by 52%;
- Transport emissions – up by 29%;
- Fugitive emissions – up by 24%; and
- Industrial processes emissions – up by 28%.
Australia’s emissions have increased 31.4% since 1990.
