This is a huuuge load of crap. Nowhere does this clearly say that CO2 emissions are cut by 80%, just "ultrafine black carbon" which is a pollutant more than a greenhouse gas. Aviations worst impact is by far the greenhouse gases.
The "sustainable fuel" that is so mysteriously alluded to, turns out to be made from "renewable biomass". Plant-basid fuels have been around for a while, usually as a greenwashing stunt by industries that consume a lot of fossil fuels. The amount of farmland needed to produce even a small fraction of what's needed in aviation is astronomical. Approaching 9 billion eaters, we can't afford to make food vs fuel a debate (again).
This whole article reads like it was written by the aviation company that paid for the research in the first place. This isn't science, it's propaganda.
The whole aviation industry is coping imo.
There is no way it will be an energy efficient or remotely green mean of transportation in the near future so a lot of people in this industry are quite worried they will be the next target for people attempting to fight climate change.
A good example is this video of a large YouTube channel on aviation:

It's a whole lithany of bullshit excuse while pointing the finger at these silly french people trying to reduce completely unnecessary emissions (short flights with an high speed train underneath their paths).
It's like the coal industry, they feel it's the end of an era for the aviation industry and they don't like it.
I say that acknowledging that some planes are absolutely necessary but nowhere near as much as we currently have.
It's part of the reason why we are far too late to change course. So many industries will fight progress tooth and nail, some violently I imagine.
