It's because we already have an established supply of canola for this use. We are exporting a lot of it for the production of clean fuels. We want to use that production in Canada. We're also going to use crop waste more efficiently. We're going to use forestry waste more efficiently.
To your second point, absolutely we will not be able to obtain all waste efficiently. That's why, again, we come back to the importance of life-cycle analysis. The tools we are using and are developing will account for the full emissions associated with producing, acquiring, processing, and then using those fuels. There will be a scale of fuels that are ranging from virtually zero to very high emissions—
