Again, this is not something we undertook for the 2006 report, but as the commissioner pointed out, we have recently received a petition on this subject. The petitioner basically asked for justification on the Canadian government's policy on ethanol related to the environment and to energy consumption. The petitioner also inquired about whether a detailed life-cycle analysis had been done in terms of the anticipated reduction of greenhouse gas emissions from the production and the use of ethanol.
What we do sometimes is wait for the ministers involved, who are obligated to respond within 120 days. From time to time we'll take a look at the statements and commitments made in those responses, and we will follow up. So it is possible in the future that we would do some further work on that area.
