Its True! Trees do remove CO2 from the air! The problem starts, and this is where there is much misunderstanding, with what happens to the carbon in the long term. A tree will absorb a large amount of CO2 during its lifetime, but when after its lifetime, that carbon is released again as the tree decays, or is burned as fuel, etc. The point of CCS is to place the captured carbon in a state that it can be stored for the long term (1000's of years). The problem isn't so much that we are performing processes that release CO2 into the atmosphere, but that the CO2 we are releasing is "new", as in it used to be sequestered underground in a stable form, and now it is being added to our atmosphere. That is why bio-diesel, even if it wasn't less harmful than oil-based diesel, is still an advantage because the CO2 it releases was taken from our atmosphere to begin with, making it close to carbon-neutral. The point is to stop ADDING CO2 to our atmosphere, and start removing and storing it for the long term.
