Perhaps. You have said numerous times that making the calculations on the true cost of carbon pricing is challenging. You've challenged some of the assumptions with Trevor Tombe and others who have tried to calculate the cost along the supply chain in the agri-food system. You yourself have not been able to calculate that to prove those assumptions false, although you say that they're somewhat shallow. Is that right? You've said that here today, and that's fine. I don't want to disagree with that.
Even if it's 40ยข on a $100 grocery bill, 300 economists at least have said that they agree. Even the Parliamentary Budget Officer, I've had meetings with him, and he says he's a fan of carbon pricing. Carbon pricing is the most cost-effective way to address climate change. You're agreeing that climate change is the biggest driver of food price volatility, or commodity price volatility, which has an effect on food prices. You're agreeing, in a way, that we have to address climate change if we're going to address food price inflation. Do you not agree with that?
