Because international vessels are mostly compliant, it's our local ones that haven't been. Part of the reason that they haven't been is, of course, cost. I've heard other speakers this evening indicate that one of the reasons is that the lower - sulphur oxide diesel is more expensive because the refinery up at Marsden Point doesn't produce it and it has to be imported, and therefore there is a knock-on cost effect. So if we have our coastal shipping having to buy bunker fuel at a higher price, then we actually all end up paying for that one way or another, because of the cost of the goods that are shipped around the coast of New Zealand—eventually, sooner or later, we as consumers all pay for that. But I would argue that in matters such as this where we are taking cognisance of our place as a global citizen and a good world citizen, we should be prepared and willing—if necessary—to pay the price for a better environment outcome, even if, in terms of global impact, the changes here in New Zealand will be actually very small. Those changes send a significant message to the world that we are taking our responsibilities seriously, albeit late.
