As the aviation industry strives to reduce its carbon footprint, sustainable aviation fuel (SAF) emerges as a key solution. SAF, produced from renewable sources like waste oil and non-food crops, has the potential to reduce aviation emissions by up to 65% by 2050. Despite slow growth, SAF production doubled in 2023, albeit currently only constituting 0.2% of aviation fuel used. The industry envisions a shift to 100% SAF usage by 2030, requiring scaling up through governmental support to achieve competitive pricing with traditional fuels. SAF is a critical component in the industry's strategy to achieve net-zero CO2 emissions by 2050, as it can reduce CO2 emissions by up to 80% compared to traditional fuels. However, challenges such as the limited availability of SAF and its higher cost remain. The transition to SAF will necessitate economies of scale and significant governmental backing. While SAF offers a promising avenue for emission reductions, concerns about feedstock sources like palm oil leading to deforestation have been raised. The development of SAF relies on a blend of technological advancements, government policies, and market competitiveness. The industry anticipates that SAF, alongside emerging technologies like electric and hydrogen aircraft, will play a pivotal role in achieving emission targets. With ongoing investments and advancements, SAF is poised to drive sustainable practices in the aviation sector and contribute significantly to combating climate change.
