Mr. Tim Gould:

It depends also on the extent to which one is turning over one's stock, in a sense. Countries that are growing fast also have the opportunity more readily than some advanced economies to build new infrastructure, so in a sense it also relates to how much one is looking to meet additional demand in one's country as opposed to replacing retiring infrastructure. That puts something of a constraint. When one is looking at a least-cost way of managing that, typically, when one has the opportunity to build something new and one can build zero emissions infrastructure, then that also has an impact on the way that the emissions reductions are shared across the different countries in the world.
