In September 2021, JetBlue announced plans to speed up its transition to SAF with an offtake agreement with SG Preston, contributing to its target to convert 10% of its fuel to SAF on a blended basis by 2030. Finally, the aviation industry contributes to 2.5% of global carbon emissions each year. In October 2021, the IATA announced a timeline for getting to net-zero emissions by 2050, and two-thirds of the roadmap relies on SAF. For SAF to scale, new or substantially improved technologies for processing and refining SAF will need to be introduced. The promotion of industry alliances, paired with tax credits, favorable loans, and other financial incentives will also be critical to increasing demand for SAF, while driving costs down. The high-cost, low-supply hurdle will have to be comprehensively addressed for the aviation industry to fully embrace SAF as a near-term or long-term solution for reducing aviation-related carbon emissions.
