I have no doubt that any project that gets scaled will be closely monitored for CO2 and effects locally - governments will want to know they getting something for their money. First to prove it works well enough, that they're not being defrauded by convincing snake oil, and also any unintended consequences no one mentioned.
It took years of the gigatons from burning oil, and the gigatons coming from burning forest and other plant material not being replaced by new growth that got us into this mess. We might be remediating for decades or centuries. Any and all are going to take years to ramp up to required scale - of mining, building, logistics, finance. We should get ample warning.
So long as contracts are written such they can stop when no longer needed... (I believe they'll probably always be needed until the oil is literally finished, but that's entirely different conversation!)
