One of the problems I see with CO2 sequestration is that it will be a nice way for companies to suck at the teat of taxpayers the world over.
I'm sure Halliburton-like companies have a 3 step plan to be right at the front of the money firehose when governments are forced to reduce CO2 or face even bigger costs (both financially and politically) in the coming decades.
This assumes that the only way a project like this could be pulled off would be for the state to open a "money firehose" and spray it onto buckets held by private corporations. Is there any reason it couldn't, in theory, be a state controlled venture? Especially for something as seemingly basic as "planting trees", I don't see where the corporate expertise comes in that the state could never replicate.
"The state will handle this" is not only a legitimate structure in totalitarian dictatorships, it's used across the developed western world for most public services.
