Which carbon registry and third party verifiers confirmed the removal? This marketing piece doesn't actually point to any project details / offset protocols / verifiers etc.

FWIW believe in carbon offsets but have deep skepticism about geologic storage (go see Aliso canyon as an example of geologic storage gone awry).

I've always wondered if we could find a way to shoot it into space.

Shooting the rocket would probably generate more CO2 then you are sending to space...

depends on the rocket fuel. hydrogen or hydrazine doesn't produce co2 on combustion.

If we get to a world with hydrogen-fueled rockets, we'll probably have much bigger dreams than just carbon sequestration.

The Delta IV Heavy is already fueled purely with hydrogen:

Well I’ll be a buttered biscuit

Still, you could burn that fuel in a power plant instead of e.g. natural gas, and that would offset much more CO2 than what you can shoot into space. It's just not an efficient use of energy, and any large quantities energy saved or not generated has a pretty direct impact on the CO2 that we could not produce.
