Thank you for your question, Mr. Bigras. I'd like to answer you in French, but I hesitate to do so. So I'll answer you in English.
Regarding the efficiency of the EU emission trading system, the emission trading system is the cornerstone--and I'm responding on behalf of Mr. Delbeke here almost. We clearly see it as a successful experiment at this point. It is not an experiment without its issues. Mr. Delbeke and I have agreed and have disagreed over the years. But it is certainly a market that is working, and the working and the market has been started in record time. There's absolutely no doubt about it. And it is making companies pursue reductions, and changing the mindset of the corporate boardrooms of Europe. On the RWE board and the Shell board and the BP board and the Endesa board, people know what the price of carbon is every day, and they make decisions based on that.
So is it an efficient way to drive change? Yes, it is a very efficient way to drive change.
