Sustainable Aviation Fuel
Sustainable Aviation Fuel (SAF) represents a critical pathway towards making air travel more sustainable by reducing its environmental impact. As technologies advance and production scales up, SAF will play an increasingly important role in the future of aviation.
What is SAF?
SAF is a liquid fuel currently used in commercial aviation. It’s capable of reducing the aviation industry's CO2 emissions by up to 80%.
A variety of sources (feedstock) can be used to produce SAF, including, but not limited to vegetable and bean oils, waste oil and fats, green and municipal waste and non-food crops. It can also be produced synthetically via a process that captures carbon directly from the air.
Azure’s facilities will produce SAF primarily using canola and soybean oils, while having the capability to utilize other renewable feedstocks depending on market pricing and availability.
Why is SAF Sustainable?
SAF is sustainable because the raw feedstock does not compete with food crops or water supplies nor is it responsible for forest degradation. Whereas fossil fuels add to the overall level of CO2 by emitting carbon that had been previously locked away, SAF is produced from sustainable feedstocks closes the carbon cycle, resulting in significantly lower CO2 emissions compared to petroleum-based aviation fuel.
Reducing Carbon Emissions, Improving Air Quality, Creating Economic Opportunities
It is estimated that SAF will contribute up to 65% of the reduction in emissions needed by the aviation industry in order to reach net-zero by 2050. This will require a massive increase in production capabilities and infrastructure.
Significant acceleration is expected to happen in the 2030s as policy support for SAF becomes global, SAF competes with fossil kerosene, and credible offsets become scarcer.
SAF is considered a 'drop-in' fuel; it can be blended into traditional jet fuel, currently certified up to 50%.
