1) While tax credits in the Inflation Reduction Act aim to increase sustainable aviation fuel production, the sustainable aviation fuel industry is still in early stages of development compared to industries like electric vehicles and solar. 2) Sustainable aviation fuel supply is limited while demand is growing, and building large-scale production facilities requires overcoming barriers like lack of suitable feedstocks and financing. 3) Targeted investments are needed to incentivize farmers to grow dedicated fuel crops and support construction of large sustainable aviation fuel refineries, not just short-term tax credits, in order to accelerate scaling up of sustainable aviation fuel supply.
