Also, as previously noted by Greg O'Connor, and Michael Woodhouse asked for the reference to this—it came from Dr Gerda Kuschel who, quoted in a Stuff article in 2019, said that a rough calculation is that "emissions from a single cruise ship visiting here is the equivalent of 200,000 cars a day." That is the entire Wellington light-vehicle fleet per day in terms of the output of those ships. And, of course, there's not a lot of those cruise ships arriving at the moment, but for over half of the year, there are—or there have been, you know, when we had travel, those ships there and they were constantly running their engines whilst in port, not just in between ports but actually using them to power themselves whilst in port as well. And you can just see the air pollution in our harbours here in Wellington, in Auckland, and in Tauranga.
