    My understanding of the science is a bit shaky, but that seems a little unlikely.

    When there’s a high concentration of methane, they usually use flare towers to burn it, which turns it into CO2. (Excess from chemical processing, or landfills.) This process is for lower concentrations that won’t catch fire.

    But that still makes sense, because methane is a much more potent greenhouse gas than CO2. However, the end product from this process may not have a high enough concentration of CO2 to make sequestration feasible, or may pose technical hurdles to the sequestration methods if the gas is a lower CO2 concentration than technologies allow for. (And that’s the part where my knowledge gets shaky - I don’t know if sequestration is just pumping carbon-rich air into the ground, or if they do stuff like pressurize it until it forms liquid or solid CO2, or try to store it in such a way that it forms hydrates underground.)
