Sorry to interrupt, Ms. Grondin, but we have very little time. That is why I am rushing you a bit.
If I understand correctly, you are currently not subject to the carbon market, but what do you think about that idea in general? I see that you are making tremendous efforts. You have reduced your intensity by 28% in one year. That was last year, so from 2013 to 2014. You are making efforts. How interested is your company in participating in the carbon market? Why would that be a good idea for you?
