How much CO2 emissions can SAF reduce?

When combusted, SAF and fossil-based jet fuel emit roughly the same amount of greenhouse gas (GHG) emissions. However, during the production process, SAF produces significantly less GHG emissions than jet fuel. When the whole life cycle of the fuel is considered, SAF can reduce up to 80% fossil emissions compared to conventional jet fuel. The exact reduction depends on the feedstock and production pathway used. Biofuels that comply with the EU regulation require at least 70% CO2 emissions reduction.
