Mr. Speaker, I can confirm for the hon. member that we have, since the beginning of the development of the tar sands, had ongoing analysis of environmental issues including, of course, emission of greenhouse gases.
I would remind the hon. member though that the Prime Minister has made no commitment with respect to any particular energy source. It may be that Canada will be providing low emission Canadian gas which might in the United States substitute for high emission American coal, which would be very beneficial for climate change purposes.
