Even as they emit CO2 from burning fuel, planes also affect the concentration of other atmospheric gases and pollutants. They generate a short-term increase, but a long-term decrease in ozone and methane, and heightened emissions of water vapour, soot, sulphur aerosols, and water contrails. One of the most prominent trends in the aviation fuel segment today is the rise and adoption of Sustainable Aviation Fuel (SAF). Derived from renewable resources such as plant oils, waste oils, and agricultural residues, SAF is seen to significantly reduce greenhouse gas (GHG) emissions, compared to traditional jet fuel. What makes aviation fuel sustainable?
