Yes, I believe there is some debate as to effectiveness given they’re still a carbon based consumable producing of CO2. If for example it takes 10 times (number plucked firmly from my backside) the energy to produce one barrel of biofuels as is contained in said fuel then it may only be addressing supply rather than environmental concerns. It would also be addressing it in a very inefficient way potentially contributing further to the problem.
Of course, the absorption of CO2 in the production of biofuels means their is a direct cycle but I’ll be honest and recognise I’m talking above my pay grade here. Perhaps someone else can shed some light.
My broader point is that the challenges posed to the aviation industry are almost unique in their complexity but that doesn’t dismiss the problems caused by the increasing demand for everyone to fly everywhere with no end in sight for a reduction let alone permanent end to aviation emissions.
