I am not in a position to answer your question. We did not examine it with a view to drawing a comparison. We used the two examples that you have just mentioned to show that this type of system was in place and, as you said, could be successful. We used the European example to show that there were risks, such as the fluctuating cost of a tonne of carbon on the European market. Apart from that, we do not have enough comparative analyses of the various types of approaches used for emissions trading. That is why it would be very difficult for us to address that.
For the time being, it is important to know that we have absolutely no idea how the Canadian system will operate. In the report, we stated that there was relatively limited expertise available for developing this system. Bear in mind that when the government was advocating this approach, we were supposed to be in a position to use it to cut greenhouse gases by 50 per cent. If the approach is not retained, we will know, because it is purely mathematical, that most of the reductions will not be achieved. It was a tool that was favoured to substantially reduce greenhouse gas emissions.
