I think you've answered it, but people I talk to always have two questions. One is whether there is evidence that having a price on carbon will reduce GHG emissions. I think you've answered that, but I'd like you to speak to it again.
Second, as the price goes up.... I'll use a simple model. If somebody is paying $100 now because of the carbon tax and they're getting $110 back, if they ended up paying $200, do they potentially get a rebate that is the equivalent, so that they might get $220 back? Is there some sort of a magic number on the price of carbon, such that it starts to negatively impact even those 80% of families along the way?
Those are the two questions.
