Many landfills in the US capture carbon emissions. My local landfill sells their methane to the local gas utility.

Many US landfills capture methane, since they can then profitably sell/burn it. I haven't seen anything about them capturing all the CO2 emitted, which would be much trickier.

And then people burn the methane in their stove, thus producing CO2.
