The problem with being a grassroots organisation is that you are honour-bound to tell the truth - even when popular consensus has decided to disagree with you. So sadly it falls to me to break it to you that biofuels are not going to solve the thorny issue of aviation emissions.
Don't tell Richard Branson that though - he's hellbent on greenwashing his expanding empire by running his planes on biofuel "around the start of the next decade" - and one 747 by the end of 2008.
