I can jump in there.
This discussion is surreal. Regardless of the targets—you've got two deep targets—you're talking significant reductions from what we're going to do anyway. That requires a response. If one announces these are the targets, one needs a response to hit the targets. What folks are saying, including me, is that if you're serious about this, these are the types of things you need to do, and, yes, there will be costs. There will be public costs, there will be private costs, there will be hits on exporters and importers, but there will also be benefits, and that benefit story is missing.
Regardless of the target you take, when you're talking about reductions of the kind that are being floated around and contemplated in this room, you're talking about significant deployment of technology, significant change in behaviour. The five megatonnes that were just announced for carbon capture and storage, looking for $2 billion from Parliament, is going to reduce five megatonnes. We need 50 megatonnes under either scenario, either target you're looking at.
