I’ve pointed this out before, but here is a quote from a Bloomberg article:
Over the next few years, European airlines must start to comply with stricter decarbonization rules, which will spell the end of the cheap-fare era, writes Lara Williams. Reaching net zero by 2050 looks like a nearly impossible climb, and the costs of doing so will make ticket prices a lot less palatable for passengers (who, by the way, are showing only growing hunger for flights, whatever the costs).

More specifically, the EU wants to see, apparently, a 55% reduction in emissions by 2030. With no existing tech to achieve that, that means in six years, airlines might have to cut their flights in half, leading to super high prices for tickets. The goal, as the speaker of the British parliament previously said, is to leverage the willingness for Covid lockdowns into climate lockdowns.
Net Zero will be as successful as Zero Covid – which is to say, a failure that causes enormous harms to individuals and society itself without adding any benefits.
