So my view is we absolutely need to support this. Obviously, it will make a huge difference to air quality because shipping emissions, particularly when they're docked in the harbour, increase nitrous oxides. There's particulates in the air; air quality monitors in downtown Auckland have shown significant increases in air pollutants over recent years which come from the ships docked in Auckland harbour, and so on. We're talking about fuels here that have been described as Marmite-like; thick, black, viscous, basically the lowest grade fuels available to humankind.
