The 2020 target is a requirement for what Canada's total emissions will be in 2020 relative to that 2006 baseline. So that's an absolute emissions target that we need to attain.
As we develop our policies for how to attain that, we need to factor in the growth that we're expecting in different sectors. For example, the expected growth in oil sands is one of the factors that we take into account.
I need to point out that the oil sands is currently not the largest source of emissions; it's actually not nearly the largest source of emissions. The electricity-generating sector accounts for about 17% of Canada's total greenhouse gas emissions, and the transportation sector accounts for about 25%.
The issue is that oil sands are growing, and therefore we need to factor into our plan the projected growth in the economy and the jobs that represents, balanced with the emissions that will be coming from it.
