What we've set up here is a system which says there will be a pricing mechanism from 2025 and the sector will design that—obviously, in partnership with Government. But the intention is to say that if they don't come up with that, then it will become part of the emissions trading scheme via the processes, which is the least-best outcome, right, because of how the sectors work. But that creates a deadline that says, actually, the incentive then flips on its head, and the incentive is to get that work done as fast as possible rather than to defer it, which has been the experience both in New Zealand and overseas.
