Now, that, admittedly, does come with some issues around planting trees as a means of offset. I think the good Simon Upton, the Parliamentary Commissioner for the Environment, made a very good point in his report some years ago, which pointed out that, actually, the best way we could avoid that problem would be to only allow forestry sequestration for farmers to offset their methane emissions, because they have a similar life cycle to the life cycle of the pine tree, in terms of emissions.
