A SAF (Sustainable Aviation Fuel) powered flight is a flight conducted by an aircraft using aviation fuel produced from sustainable and renewable sources. SAF is also known as aviation biofuel or biokerosene.

The purpose of using SAF in flights is to reduce the environmental impact of aviation, as conventional aviation fuel, known as Jet-A or Jet-A1, is derived from petroleum and contributes to greenhouse gas emissions and air pollution.

SAF is produced from renewable sources such as vegetable oils, animal fats, organic waste, or biomass, and can be blended with conventional fuel or used as a direct substitute. During combustion, SAF emits fewer carbon dioxide (CO2) and other pollutants compared to fossil fuel, making it a more environmentally sustainable solution for the aviation industry.

Airlines and the aviation industry are gradually adopting SAF as part of their efforts to reduce their carbon footprint and pursue greater environmental sustainability. The use of SAF in aviation is seen as a step towards achieving the industry’s goals of reducing greenhouse gas emissions and contributing to global efforts to combat climate change.

Ryanair, the low-cost airline, has recently expanded its partnership with Neste, a world-leading supplier of sustainable aviation fuel (SAF). As a result of this collaboration, Ryanair is now using a 40% blend of SAF to power its entire schedule of flights at Amsterdam Airport Schiphol (AMS) since April 1st.
