With their hydrogen-electric engine taking its first flight, ZeroAvia have made history in Gloucestershire! As I told #wef23 - we have the innovation & creativity to build the world-beating industries of the future. And we are one step closer to guilt-free flying ✈

@ZeroAvia In the same way as that cake is not zero calories, flying is not zero carbon, and won't be for a long time (if ever). It's not about guilt, it's about understanding that avoiding climate breakdown means changing *everything* about the way we live, including A LOT less flying.

@ZeroAvia Why are you insisting on doing these cringe videos? You aren’t liked, won’t ever be liked and we cannot wait for you to disappear to pyramid scheme heaven.

@ZeroAvia We love innovation, but we've heard this before. Green flights are always just around the corner. The reality is that clean technology won't be here in time to meet our climate goals. There's no way around it. The people who fly most have to fly less.

@ZeroAvia While we’re waiting for that, how about a nice big tax on aviation?

@ZeroAvia Oh it's about removing the guilt is it ? Not about preserving a precious environment that in last 100 years humans have wrecked and in the next 100 years could make large swathes uninhabitable. I suppose you SHOULD feel guilty for that.

@nadhimzahawi Talking of flying Grant… you never did answer the questions as to why you took your private aircraft off the British register and put it on the FAA register..nothing to do with getting round problems caused by Brexit.. (which you supported) of course… ahem.

@ZeroAvia Might want to start closer to home Sebastian

@ZeroAvia Only in Weetminster do they think like this. I don't feel guilty about flying to go on holiday.

@ZeroAvia Sorry Who is giving the go-ahead for these very cheesy annoying patronising videos

@ZeroAvia Actually, I was thinking, do you lot ever do the jobs you're paid for or do you all just make mini movies all day? #toriesout #ToriesUnfitToGovern
