As we put a price on carbon, I don't think there's any doubt that in the end energy prices will go up. How much will they go up? That's a matter of speculation.
I'll refer specifically to the fuel that most of you are familiar with, and that's gasoline. It's impossible to predict what the pump price of gasoline will do. The variety of factors and variables at play, and ultimately the competitive markets, determine what the price at the pump is.
But what I can say is that when you combust a litre of gasoline, you emit two and a half kilograms of carbon dioxide, so when we look at the prices of carbon in terms of the input cost to the process--not the price at the pump, but the input price to the cost of the process. I mean, it's two and a half kilograms per litre.... Whether the carbon price is $30 a tonne, $50 a tonne, $100 a tonne, or $300 a tonne, you can do the math as well as I can in terms of what the potential input cost to the production process may or may not be.
