Mr. Harvey, we did not do those calculations. Those calculations cannot be done sitting at the end of a table. However, I will correct what you said about the price of a tonne of CO2. We have absolutely no idea what the average cost of a tonne of CO2 is. We have no other reference than the European market. Over a year, the prices have gone up and down. We had a graph that showed that. The price can fluctuate from one month to the next, going from $15 to $30, dropping to $10, and going back up to $25. So there is no number that can be used as a reference. This is a stock market, so there are fluctuations.
