The International Air Transport Association (IATA) has lowered its forecast for global sustainable aviation fuel (SAF) production for this year, stating that government mandates in the EU and the UK have pushed up prices, restricted supply and slowed the industry’s progress towards reducing emissions. IATA said new estimates show that SAF output is expected to reach 1.9-million tonnes, or about 2.4-billion litres, this year, which is nearly double the one-million tonnes produced in 2024 but below earlier expectations.
