It may not scale, but it's not greenwashing - for it to be green washing, you'd need either claims of lower co2 to be false, or pretend that this solves the issue completely.

Lufthansa, at least - when I checked - made no such claim. I reviewed their compensaid site thoroughly (afraid it's just greenwashing), and their communication seems very honest.

"Net zero by 2050" sounds like greenwashing to me.

My dictionary defines greenwashing as "misleading or deceptive publicity disseminated by an organization so as to present an environmentally responsible public image".

This is exactly what this industry is doing.

Exactly. Biofuels can be very useful, but only by also drastically reducing overall energy consumption. Flying uses a lot more energy than trains.

Is that if we wanted to produce all of our aeroplane fuel here though? Presumably we don't do that at the moment.
