In a guest editorial in Flight's Airline Business magazine, Greenpeace chief scientist Doug Parr argues that biofuels are simply not going to work as an acceptable substitute for kerosene.
Parr makes three broad points: there's not enough arable land to grow the required crops; opening up virgin land to fix that has unacceptable knock-on efects; the knock-on effects of using biofuels are anyway unpredictable and it is quite likely that their use will in fact increase greenhouse gas emissions.
I would say it wouldn't I, but I'm pleased to see Airline Business hosting this kind of piece, and I'm just as pleased to see Greenpeace making good use of it.
