Again, if you look at the International Energy Agency's low carbon scenario, oil prices are higher than what probably any oil sands company is using today to justify their projects, even in their 2°C scenario. It really does come down to what you believe the relationship is between global carbon emissions and that global oil price.
In response to the chair's question, I think the question is how at risk are these benefits. It really does boil down to whether you believe a low carbon scenario is also a low future oil price scenario as far as the revenue the producers receive is concerned. There are forecasts that will give you either side of that story. There's no universal consensus on high versus low oil prices tied to low carbon emission scenarios.
