I guess I would just point out that I wouldn't talk of carbon pricing as a discrete thing, like a yes or no. It's not like a light switch. If it is a light switch, it's like a dimmer. There are lot of different levels of carbon pricing. You could have a very strong carbon price that would get us to our target, or a smaller carbon price that wouldn't get us to our target.
