On the tar sands and the role of carbon capture and storage, I don't see that anybody is seeing a future in which we can actually meet deep reduction targets without some significant investment in carbon capture and storage. As the panel that just reported has pointed out, we do have some of the geological formations that allow that. We have capacity to build infrastructure, etc. It's not that this is impossible; it just has not been done.
Then the question becomes, who's going to pay? Who's going to be responsible? In what framework does this reside?
If we put in place an appropriate, aggressive greenhouse gas reduction target that constrains carbon, which creates a price signal, we will see deployment of that technology, because it is one of the ways that industry can really reduce emissions. We have to do that, and it is being done. There are projects in the United Arab Emirates. There are projects starting up as pilots in Europe. There is a project in Australia. This is happening around the world. It's a collaborative exercise, and really, it's only a matter of working out the framework and the arrangements for that. So it certainly should go forward.
What does that mean for the Alberta tar sands? Well, I don't think I'm the first person to be saying that it's an overheated situation and that we should have a more appropriate pace and scale of development at the very least. We need limits. There are no limits right now, and in the absence of that, it's an absolute free-for-all, using the global atmosphere as a commons to pollute. The implications for the boreal forest and for water are immediate and pressing. We have so many reasons to do this.
