In 2023, the Australian government released the Aviation Green Paper, highlighting the challenges faced in decarbonising the aviation sector as the transition to clean energy accelerates. Australia's aviation emissions surpass those of the country's bus and truck emissions combined, making it a critical sector for emissions reduction. The Australian Renewable Energy Agency (ARENA) introduced the Sustainable Aviation Fuel (SAF) Funding Initiative in 2023 with a focus on decarbonising aviation, supporting domestic SAF industry development, and identifying projects to boost future supply. SAF, a drop-in fuel, plays a significant role in decarbonising the sector and can blend with conventional jet fuel. Various feedstocks like vegetable oil and waste oils are used to produce SAF through processes like the Hydroprocessed Esters and Fatty Acids (HEFA) pathway. ARENA is also exploring emerging technologies that use waste feedstock for SAF production. Strict testing standards ensure the safety and blending guidelines of SAF. Sustainability in SAF is crucial, with a focus on replenishable resources and lower carbon emissions. The CORSIA scheme by the International Civil Aviation Organization sets standards for sustainable SAF production. The first project funded under the SAF initiative, Jet Zero Australia, aims to explore the viability of commercial-scale low carbon liquid fuel production in Queensland. This project will significantly reduce CO2 emissions, secure a local supply of renewable diesel, and position Queensland as a leader in low-emissions biofuels.
