Getting fossil fuel sourced carbon permanently out of the atmospheric carbon cycle with currently available tech (i.e. planting trees doesn't work because they burn and decompose) is an absurdity.
Perhaps the best you can do is mitigate warming factors, like investing in burning previously vented methane, but that might be risking triggering a Cobra Effect, https://en.wikipedia.org/wiki/Perverse_incentive#The_origina...
There's no realistic tech on the horizon that can actually reverse novel carbon emissions. Even if we had that kind of carbon capture tech, we would likely need to devote at least as much energy as we got in aggregate from all our fossil fuel burning human civilization captured over the past century to the project. We're several orders of magnitude in renewable and nuclear generation fleets away from that possibility.
The adults in the room aren't talking about reversing carbon pollution on human timescales anymore. They're talking about planetary heat engineering to adapt to a more densely insulated Earth. That means adapting to a changing environment on the ground, as well as possibly limiting the amount of solar energy entering the system in the first place.
Humanity is entering childhood's end. We can't depend on our mother to do all the work of providing a safe cradle for us anymore. We either grow up and take ownership by proactively managing our environment, or we die. The teenage years are usually painful.
