Thank you very much.
Thank you, witnesses. This has been very helpful.
It's a bit ironic, because on Tuesday our session was supposed to be about mechanisms, modelling, and target setting, and a lot of it turned out to be about adaptation. Such is life. It is true that today we're talking about international matters, but in fact you're filling in some gaps from Tuesday.
I want to begin my questioning with John Drexhage, who has a great deal of experience in this field. I want to understand in terms of the Kyoto model, first of all, the balance that was envisaged and is now evolving between domestic action, the so-called made-in-Canada plan, and international activities such as carbon emission trading. How has that idea evolved over time, and why have other nations said they're not going to try to do it all internally? I'm thinking of countries like Holland. What's the idea behind that? And in your view, is that a sound idea?
