SUSTAINABLE AVIATION FUEL (SAF):

For turbine-powered aircraft currently using conventional jet fuel, the single-largest potential reduction in aviation’s GHG emissions — and a key to reaching goals for reducing them — will come about through the broad adoption of SAF. Burning SAF still emits CO2 in the same way as kerosene but the difference is that SAF product extracts this same amount of CO2 from the atmosphere when the feedstocks are grown.

                                                                                            What is a blended fuel?                            

An SAF blend is a mixture between conventional fuel and unconventionally synthesized mixing agents. SAF can come from various sources whose chemical constituents can be converted into the pure hydrocarbons that usually make up jet fuel. For now, SAF are used in mixtures with kerosene (blended up to 50% with conventional jet fuel) but they are expected to be used pure.
