Our Emissions

How we compare.

The facts about our contribution to global emissions.

Australia’s greenhouse gas emissions have increased by four per cent since 2005. But our net emissions — the emissions we produce less the amount we take out of the atmosphere — have fallen by 20 per cent since 2005, which is faster than every other major commodity-exporting nation of a similar size.

The largest amount of emissions come from electricity, gas, water and waste, but emissions from mining are growing fastest. Emissions from electricity and the land sector (e.g., agriculture and forestry) have been falling, which has offset increasing emissions from mining, transport, construction, and the residential sector.

WA is the fourth largest emitting state in Australia. Other states have reduced their net emissions since 2005, but WA’s have increased. Our performance relative to other States reflects the different industrial make-up of our economy. States like Victoria, whose economies rely less on ‘difficult to abate’ industries, have a much easier task reducing net emissions.

Several sectors have contributed to increasing emissions in WA. Due to rising global demand for WA’s resources, the mining sector has contributed significantly to this growth. However, over the long term it is expected to make a major contribution to global emissions reduction, including as a producer, exporter and user of green hydrogen; the critical minerals needed for clean energy technologies; and LNG.

WA’s mining sector is also integral to our prosperity and well-being. Its contribution to WA’s economy far outstrips the contribution of any other sector in any other State.
