Europe's jet fuel shortage should fast-track sustainable aviation fuel, with Neste the cleanest, highest-conviction play. The IEA saw about six weeks of European jet fuel left in mid-April, with 75% of imports once routed via the Middle East, and the EU is using the crisis to push ReFuelEU blend mandates. Neste, the top SAF producer, is scaling European plants to 2.2 million tons a year by 2027 with deals at 100+ EU airports. TotalEnergies, Gevo and Aemetis are secondary plays. x.com
