Apparently the average car produces 4.36 tonnes of CO2 in one year.
Different species of trees absorb different levels of CO2 not only when
planted, but also as they grow on to reach full maturity e.g. mature Oak
apparently locks up approx 3 tonnes of C02. Therefore numbers of trees
required to offset the average cars annual emissions depends up species
proposed to be planted, size at time of planting and potentially, the
anticipated life of the tree itself. Further, don't forget the leaf-fall
re-releases CO2 annually, so that may have to be factored in also.
I think that when you begin to tot all of the tree numbers up, and they are
vast, you may find that there just isn't enough land in the UK to make such
schemes viable for our levels of traffic.
