The CO2 myth is junk 'science' st its worst. Not a great deal different than a modern day Salem witch trial with a tux.
Sure...
The correlation between the rise in CO2 levels and the global temperature rise is widely acknowledged by an overwhelming majority of the scientific community.
Now, you can entrench yourself behind the disagreement that some have over the magnitude and consequences of said warming, or the exaggerations of those who tell fifth hand accounts of scientific reports for the advancement of their own agendas, but if you cut through the crap from both sides of the argument and listen to what basically all of those who follow scientific reasoning and who have spent a significant proportion of their career studying the subject have to say, then the only debate is what to do about it...
On your side, those of the 'Trump' cult who'd rather disregard every fact that doesn't suit them and keep doing what we do since it keeps snowing in January anyway so how bad can it be?..
On the other extreme, there's the eco-freaks who say we should go back and live as cavemen so as to stop any further harm to mother Gaia.
And in the middle, there's all the rational people who are trying to debate how to best deal with it and find compromises between reducing the pace of the warming, weathering its effects and still accommodating global population and economic growth amid the already evident signs of increased weather-related macroeconomic and humanitarian hardship.
But it's easier to just stick your head in the sand, right?
Now, I don't believe for a second that CX or any other airline are dipping their toes in the alternative fuel pool for the sake of the planet. They couldn't give a damn about that.
They're after a source of sustainable fuel in a time when oil is falling out of favor and, more importantly, one which is not dependent on wild market fluctuations. CX have shown us how inept they are at dealing with that.
It's not the stupidest thing they've done (which isn't saying much) but don't believe for a second that they're any sort of pioneers in the field. This is pure
PR.
CX, as usual, will only properly venture into using bio fuels when every other airline has cleared the way and proven it to be a viable solution, and then they'll still find a way to mess it up.
