Well, sir, the problem is that under the Kyoto Protocol there is a mechanism called the “clean development mechanism” that establishes the process that has to be gone through for certifying international credits as compliant with the Kyoto regime, and the architecture of that process is very cumbersome. Despite efforts to fine tune it that have been made in recent years, it continues to take a long time. There's a long lead time in getting projects approved through that mechanism that are eligible as Kyoto-compliant international credits.
It's not like a free market where the market has the ability to respond. It's a cumbersome and bureaucratic process, and that's one of the aspects of the Kyoto Protocol that Canada needs to work on improving for future periods. I think you will get pretty widespread agreement from experts in the field that it's unlikely that there will be sufficient numbers of good international credits available by the year 2012.
