Ok, so this particular biofuel is not sustainable. The point I think, is that it demonstrated that it is feasible to look at biofuels as replacements for petroleum based fuels... The aircraft ran 1 engine on "refined coconut oil" to put it simply.
But, the "green people" don't like it. There is evidently no satisfying these people. We can't drill for more oil because it harms the environment and we can't grow green crops for biofuels because that will harm the environment too... Digging for selenium for solar power screws up the land and wind turbines spoil the view of nature. Sheesh...

Increased use of biofuels could also prompt food shortages, campaigners warn, as greater areas of farmland are turned over to biofuel production.

The 'greens' complain that there are too many airports, seaports, shopping malls, etc... So, if you have fewer people, wouldn't you need fewer structures?
I do believe that if the "greens" have it their way, we'd all be on foot. Of course, that would necessatate eating more to sustain human energy levels.
Then they'd complain about the farts...
