And this is a good journey that we're on, a good process that we're on under the Kyoto process, under the UNFCC.
Can I go to your call for a climate change investment fund. Because today is all about fiscal tools, I'm trying to understand better how this climate change investment fund might work. Your brief doesn't go into too much detail on fiscal issues. You talk a bit about the accelerated capital cost allowance and the oil sands, you talk about the need to use other fiscal issues, but you don't actually put forward to us here at committee more detailed measures. Could you help us understand how this investment fund would operate in practice?
