Another really good idea.
Trees soak up carbon dioxide while they're growning.
But you have to chop them down once they've grown and store them somewhere where the CO2 which is releaced when they decompose isn't released back into the atmosphere.
For instance, the rain forrest, so called lungs of the world, actually has a net CO2 absorbsion of about 0. That is, it produces through decomposition about as much as it absorbs. Now if we could prevent the re-release of the CO2 we'd have a fantastic CO2 sink.
Build roads. May sound daft, but they absorbe CO2 for a considerable amount of time.
Remember the biosphere 2 experiment? They abandoned it because they couldn't figure out where the oxygen was going?
It was going into the concrete of the structure.
They'd messed up their soil cultures a bit, having too much bacteria, producing too much CO2 and taking in loads of oxygen in the process. Some of this CO2 was absorbed by the concrete, so the net oxygen levels dropped.
Course you should cycle on the road once you've built it
