The ReFuel EU Aviation proposal offers targets for sustainable aviation fuel (SAF) and synthetic aviation fuels from 2025 to 2050 The policy proposal safeguards competitiveness in the air transport industry while ensuring that CO2 emissions linked to fuel in the aviation sector may be reduced by circa 60-61% by 2050 compared to the baseline year The emergence of SAF on the market would lead to a dramatic decline in the reliance of aviation on fossil jet fuel, leading to a 65% reduction of the latter by 2050
