EU targets aimed at increasing the use of so-called sustainable aviation fuel (SAF) by airlines in a bid to cut fossil fuel emissions are “not achievable,” the head of the IATA airline industry body said Thursday. Targets set by the European Union in 2023 call for SAF to constitute 20 per cent of airlines’ fuel use by 2035, up from around two per cent currently. “We’re not seeing progress in terms of the production of SAF,” IATA chief Willie Walsh told an industry event in Paris. Last month, the IATA estimated that global SAF production would reach 1.9 million tonnes in 2025, nearly double the amount produced the previous year. But production growth is expected to slow this year, reaching 2.4 million tonnes—which would represent just 0.8 per cent of a fuel mix still dominated by traditional jet fuel.
