I agree, Blue Origin at least was thoughtful enough to use fuel that doesn't emit CO2.

Branson is more likable but does seem like he's just trying to defend his title of being the eccentric billionaire, rather than thinking too hard about the future.

I thought that too, but apparently the BE-4 engine uses LNG :/

They could always electrolyze seawater. We need to deter large-scale greenhouse gas venting, not energy uses of all kinds.

[soperj]

they could, but that's not where it comes from.
