I believe the trees continue to grow over the intervening near-decade between harvests, sequestering CO2 not only in the part of the bark that is harvested (which sounds like it is potentially only a meter or two off the ground) but also as new growth along the rest of the tree. I suppose that that statement implies that, on average, they harvest 1/73rd of the growth that a tree has had since the previous harvest. (Note I am not attempting to state whether that claim is true or not, merely offering one potential explanation of how the trees might sequester 73 tonnes CO2 for every tonne of cork harvested)
