Around 10 percent of the world's fleet remains stuck with low-sulphur fuels. A large proportion of them operate in countries that are still not signatories. There are 99 signatories out of all the world's countries. So New Zealand is actually blessed that many of the ships and shipping companies already coming to New Zealand comply with these rules, but they're not getting their fuel in New Zealand. They're coming here bunkered up; they're not buying fuel in New Zealand. So the issue really affects most severely our own coastal shipping fleet. And it's for that reason, when we look at the submissions, the majority of submitters recognised the need to address climate change risk. They agree that meeting the conditions of the treaty will benefit New Zealand's international reputation. However, they are extremely concerned about the time frames and the cost of getting hold of this fuel and what kind of port facilities will be required to receive waste residues from the low-sulphur fuel management systems that might be required on ships, as well as the ballast waters.
