The development of SAF has facilitated the way for airlines around the world to reach net-zero emissions in the upcoming years. While it is certainly a much cleaner and less polluting alternative to conventional fuel, there are still some disadvantages of sustainable aviation fuel. Globally, SAF still makes up less than 0.1% of aviation fuel and it costs about four times as much than kerosene. Furthermore, some experts argue that investing in SAF is not the right strategy to decarbonise the engine technology and believe a much better way would be to invest in technologies like hydrogen and electric propulsion as these are the only long-term solutions to aviation emissions. Nonetheless, more and more companies are now investing in groundbreaking technologies to turn a variety of feedstocks into aviation fuel and an increasing number of airlines are betting on it, making some decisive steps in the right direction in the run to net-zero emissions.
