Yes, the comment I replied to is technically right in that there are some tiny countries out there. Or they would be, if the rocket in question would've been a vastly larger rocket that burned a carbon containing fuel. The New Shepard tourist joyride is tiny for a rocket and its exhaust is water vapour.

Where did they get all the hydrogen? How did they make the rocket. While it may not emit much carbon on launch day, it will have taken a shit load to produce it.

I was talking about the direct emissions of launching a rocket. The indirect emissions are obviously vastly larger and might as well include everything in the wider economy that enables stuff like this. Just maintaining the necessary industrial capacity is already a huge strain on the planet. That's what I'm after with these comments. The rich fucker joyride is a largely inconsequential yet overtly visible result of a bloated system hiding in plain sight. The aerospace sector as a whole is just the tip of the iceberg of a global industrial society in ecological overshoot.

Hydrogen is usually produced from natural gas with all the carbon being released as CO². So just the direct cost of making the fuel is already terrible.

Starship doesn't use Hydrogen. It used methane and liquid oxygen.

So hydrogen creation is carbon neutral, didn't know that! /s

Although I doubt it, hydrogen can be produced using renewables.

It's still going to be significantly "greener" than using methane as a propellant, though.
