> If commercial flights all used 50/50 renewable fuel that would cut greenhouse emissions in half.
Airline emissions aren't that bad compared with everything else, but they aren't being decarbonised at the same rate like everything else, and on top of that they are growing dramatically.
In 2019 there were 4.5b passengers globally. In 2006 there were 2.25 passengers globally, so doubled in 13 years. Planes are slightly more efficient now, but there's a long tail of less efficient planes.
Moving to 50:50 biofuel may save a decade of growth, but it's not a silver bullet.
