- SAF must make the biggest contribution to the 2050 net zero goal.
- Different SAFs have a different climate performance based on a full life cycle analysis of greenhouse gas reductions.
- Both incentives and regulation are needed to ramp up SAF production – but the first 10% will be the hardest and riskiest.
- Global governments must back net zero through ICAO.
SAF must make the biggest contribution to the 2050 net zero goal
New aircraft/engine technology is unlikely to deliver new sustainable propulsion methods (electric or hydrogen-powered) beyond short haul flights by 2050, and operational efficiency gains can only reduce the growth in emissions.
This means that SAF must make the biggest contribution towards net zero in 2050, with economic measures offsetting the remaining shortfall.
IATA expects SAF to contribute 65% of the reduction in emissions needed to achieve net zero in 2050, while European aviation’s ‘Destination 2050’ modelled SAF’s contribution at 34%.
