The research shows that the benefits massively outweigh the costs, and the benefits are literally to the owners of the vehicles. So any additional cost—and, frankly, there's no evidence there will be additional cost—is offset by massive savings throughout the economy because New Zealand businesses and households are spending less money on imported oil to make the very same trips. And so that helps our current account balance and it just saves people a lot of money. So that is why, if you were looking at one of the most cost effective or beneficial economic ways to reduce emissions, these two policies are it, because normally you look at a marginal abatement cost and you'd say, "We want a lower cost way of reducing emissions." The marginal abatement cost for the "feebate" scheme alone is estimated at between negative $71 and negative $332 per tonne of CO2. Now, what that means is that it doesn't cost us money to reduce carbon emissions through this policy. We get savings. So we're reducing emissions and we're saving money, and that money is money in people's pockets that they can then spend in the New Zealand economy.
