Sure. There are many avenues. This is consistent with working through initiatives within the international community. What I was speaking about with the credit enhancement is a little bit different from the Kyoto Protocol clean development mechanism in that this isn't about Canada donating and paying the whole shot, it's just about us lending our balance sheet so that countries can get a lower cost of capital, and in return for that, we could get some of the business.
Where it also gets interesting is that there are some products out there now with things called “carbon kickers”. The way it works is we could do the deal with, say, Mexico, which has a $5 billion infrastructure plan to reduce carbon that involves subways and trains, and we could do a deal where we would help to backstop their bond issue for $5 billion to do it, and our companies would get some of the contracts and then we would also get some of the carbon credits that might accrue, because it's been approved under the UNFCCC framework. So it could be a kicker.
Presently, financial markets don't put any value on carbon credits, so it would have to be a kicker. I'm not suggesting that we should do this as a substitute for engaging internationally, but it's entirely consistent and complementary to that kind of approach.
