While the aviation sector will have to overcome huge challenges to achieve its goal of net zero carbon emissions by 2050, the industry has made great strides in its decarbonization journey. The uptake of sustainable aviation fuel (SAF) is growing, with global SAF capacity expected to be nearly 6 billion gallons by 2030 from 1.3 billion gallons in 2023.1 However, today it is severely constrained by the limited availability of alternative aviation fuels that are low in lifecycle carbon, cost-effective, safe, and high-performance.
