But already, since the announcement of the Supplementary Order Paper and the regulations that go with this bill, carbon price has moved up. So it was at about $25, or a little bit under, for most of the last 12 months or so, but, today, it sits at $31.40. Already, that's having an impact. So at the committee of the whole House stage, the Minister conceded that at $25 a tonne currently that works out for a litre of petrol at the pump, New Zealanders are paying about 4c a litre into the emissions trading scheme contribution. But at $35, the Minister conceded that that moves up to 9c a litre. Now, that might not be a lot to many people. It may not be a lot to many people. And I suspect, actually, that's not enough to probably change driving behaviour. But all it does is add to the cost of living of New Zealanders at a time when we can least afford it. It's not of itself going to be sufficient to change behaviour. Indeed, the Minister has indicated that the price needs to go up vastly higher than the $35 that is currently mooted.
