Emissions have fallen steadily since 2005, but progress has plateaued in recent years. Stronger action is needed to meet the 2035 target such as expanding clean electricity, adopting cleaner fuels, and advancing new technologies.
Emissions have fallen from electricity generation, but transport, stationary energy, and industrial processes continue to rise, showing that sectors are decarbonising evenly. Stronger policies and faster electrification are needed to close the gap.
Carbon dioxide (CO2) still makes up most of Australia’s greenhouse gas emissions, but slower progress in cutting methane (CH4) and nitrous oxide (N20) shows difficulty in tackling pollution from farms, waste, and industrial processes.
Fossil fuels continue to dominate Australia’s energy mix, with coal, gas, and oil accounting for the majority of consumption. However, renewables have grown steadily, now contributing nearly 30% of electricity generation.
As seen earlier, transport is the biggest contributor to national emissions. Reducing this will require greater investment in public transport, faster electrification and a transition to cleaner fuels like hydrogen, biofuels, and renewable power.
