The Kyoto Protocol is like a practice for the actual game. In actual fact, it isn't a final agreement. As Prof. Boyd said, to combat climate change, we have to achieve global objectives in the order of 25 billion tonnes, and Canada in all that only constitutes a very small part. Are there any other options besides the Kyoto Protocol? I'll use a simple analogy. If, in 2005, I promised that I'd weigh 30 kilos less by Easter 2007 and I weigh 60 more today, it's not very likely that people would believe me, especially if I haven't yet started an exercise program. Canada absolutely has to prove its will by putting in place the tools that will enable it to catch up, if it ever can catch up. For Canada, the issue of achieving a specific target isn't so much related to the target as to the process.
