No easy solution to slash aircraft carbon footprint
An ongoing study by the Royal Institute of Technology (KTH) claims it would take a major change to reduce the carbon footprint of flights.
Jonas Åkerman, one of the researchers, says “biofuel is only one part of the solution, not the whole solution.”
Zero emissions could be achieved if hydrogen gas produced with fossil-free energy could be used, and flying 8000 metres lower, but this is some time away from happening.
“The problem is reducing the level of existing carbon emissions from the latest decades,’ says Jonas Åkerman, “and then a new airplane would have to be designed and whole fleets replaced, which could take 40 to 60 years.”
However, the recent trend towards vegetarian and vegan food could mean more possibilities of producing biofuel in the future.
