I mean the carbon market, whether it's domestic, whether it's North American, wherever. This is a question of competitiveness and economics for individual companies. It's too easy to say that if we met the Kyoto targets it would cost us $36 billion if we had to go get them in the carbon market.
Well, Alcan is some days, questionably, in terms of its intent—But we're not stupid. We would not go into a carbon market unless it was competitively advantageous for us and it allowed for the transfer of value and the reduction of greenhouse gas at a facility level, and this is what we're after.
So nobody is saying that government should invest. I would not want the Canadian government to buy Russian hot air. I wouldn't buy Russian hot air. So if you look at carbon markets, I think the only recommendation I can make to you is that you need to better understand how the market works, because the alternative to the market is a carbon tax.
