Since 1990, emissions from our vehicle fleet have increased by 90 percent, and that is far and away the biggest increase of any sector—a bigger increase than agriculture, a bigger increase than energy, a bigger increase than industry, bigger than any other sector. One of the reasons for that is because there has been a total lack of legislative or regulatory leadership in this area. New Zealand, up until today, is one of only three countries in the OECD, alongside Australia and Russia, that don't have a vehicle emissions standard. And that is one of the reasons why we have one of the dirtiest vehicle fleets in the world. It is one of the reasons why we have those increasing emissions. It's one of the reasons why we have such terrible air quality in our cities. It's one of the reasons why our vehicles cost more for Kiwi motorists to run, because of their sheer inefficiency. It's very, very clear that, as the rest of the world continues to increase its level of ambition, as the rest of the world moves to bring cleaner cars into their fleet, if we don't take action here in New Zealand, we will become, even more than we are now, the dumping ground for the dirtiest vehicles in the world.
