Hon MICHAEL WOOD: New Zealand sits at the end of a long supply chain and risks becoming a dumping ground for the world's highest-emitting vehicles without these policies. The clean car scheme is helping to expedite the transition of our vehicle fleet, and doing so is putting a massive dent in our vehicle emissions, which make up 43 percent of New Zealand's carbon dioxide emissions. Over the life of a car, clean cars are proven to have lower costs in the long run once maintenance and fuel costs are taken into account, meaning they save Kiwis money as well.
