Australian stationary energy emissions

Stationary energy is the largest contributor to energy sector emissions, which are themselves the largest contributor to how much Australia emits. Stationary energy includes emissions from fuel consumption for electricity generation, fuels consumed in the manufacturing, construction and commercial sectors, and other sources like domestic heating. The stationary energy sector makes up 53.9 per cent of Australia's emissions. Electricity generation is by far the largest source of emissions in this sector, contributing close to 50 per cent of all energy emissions. The remainder of emissions from stationary energy sector comes from direct combustion of fuels.

Emissions from stationary energy grew by 49.5 per cent between 1990 and 2007, which was largely due to combustion of brown coal. Key drivers of stationary energy emissions growth are the structure and growth of Australia's economy, the fuel mix used in electricity generation and energy efficiency improvements across the economy. These factors affect the demand for electricity and its emissions intensity, as well as the demand for fuel for direct combustion.
