The aviation sector fails to meet its self-imposed climate targets and uses 100 times less sustainable fuels than it had set. Furthermore, the targets have been increasingly watered down in recent years. This is the conclusion of a new study by the Institute for Policy Studies (IPS). As recently as 2007, the International Air Transport Association decided to aim for ten percent sustainable fuel consumption within a decade. However, in 2017, US airlines only covered 0.01 percent of their fuel consumption with sustainable fuels. By 2014, the target had been lowered to three percent, yet the proportion of sustainable fuels had only increased to 0.03 percent.
