How many of those companies actually put atmospheric carbon back in the ground, sequestered in a form that it stable for at least a couple of generations? As far as I'm aware you either pay for some trees not being cut down (for how long?) or you pay for measures that prevent carbon emissions by e.g. subsidizing more efficient cooking stoves. Both methods are not completely useless (which I why I said "mostly"), but they're not really unburning the fossil fuels I used. They also don't scale very well.
I'm actually looking for ways to offset my emissions, so I'd really appreciate some pointers if you're familiar with the space.

There's a handful but to be honest most of them are still developing their technology so they could be vaporware in the end.
One of the most mature ones, though, is Climeworks [1], and you can buy offsets from them already.
