True, air travel accounts for quite a small share of overall carbon emissions (in the region of 23% currently), but nevertheless its high profile and visibility make it an obvious target for climate campaigners.


The good news: there is an ever growing number of initiatives from within and outside the aerospace industry that aim to tackle this issue, with electric propulsion for aircraft getting most of the attention.


The bad news: electric may not be the most promising technology when it comes to moving towards a greener aviation industry.


Our guest today, aeronautic engineer and former fighter pilot Bjorn Fehrm, has studied thoroughly a number of different technologies that attempt to get green airliners up in the air.


Bjorn has crunched the numbers and has drawn some conclusions about what the thinks are the most realistic perspectives in the field of green flying. He’s summed it up in a series of 20 blog posts full of detailed information and analysis about environmentallyfriendly propulsion technologies.


The title of the series “Why e in ePlane shall stand for environment, not electric” already gives you some clues about where this is going.


Ready to listen what these are and the implications for the future of air travel?
