Hon MICHAEL WOOD (Minister of Transport): I thank the member for his excellent and timely question. The Clean Car Discount scheme alone is expected to prevent up to 9.2 million tonnes of carbon dioxide emissions by 2050. The expected marginal abatement costs for the Clean Car Discount and Clean Car Standard combined is estimated at minus $160 to minus $200 per tonne of carbon emissions prevented. The estimates are negative, meaning that they represent a net benefit to the New Zealand economy, due to large fuel savings for New Zealanders. In short, the policy will reduce emissions, clean up air quality, save Kiwis money, and reduce our reliance on volatile international fuel supply chains. No doubt the ACT Party opposes it.
