I would offer to the government the suggestion of a rising carbon price or regulations of the kind, if you look through my testimony, that I've been talking about. They dominate in California. Eighty-five per cent of their policies involve the kind of regulations I was talking about.
I'm indifferent. You can do regulations that are about as efficient as carbon pricing. It's fine to be indifferent to that, but you do need to regulate or have a rising price. Otherwise, fossil fuels are wonderful. They'll destroy the planet but they provide fairly high-quality energy. Also, their price is going to fall as we switch away from them. They're going to get even cheaper, so you have to have the regulations in pricing.
