Sequestration should not be part of a market for CO2 certificates. Sure, you could earn money by sequestering CO2 and selling certificates generated by the process. But you will have to buy them back when the CO2 leaks. And it should diffuse out of the atirahe over time, albeit slowly. So you might eventually have to buy back the certificates instead of earning the money required to maintain the filled up CO2 storage for, well, virtually forever.
